A. The composition of the castings-36/">precision casting process costs
The silica sol precision casting process can be divided into the wax mold making, shell, melting and pouring, and after four stages of the imputation inspection services for the four processes, equipment maintenance costs for auxiliary production costs. The four production process, the wax mold making, shell, melting and pouring the costs incurred by the three stages of the process yield is closely related to the accounting of the cost of casting weight than more accurate casting weight accounting. For example, if the wax mold casting weight accounting manufacturing cost, small pieces of the large cost relationship is obviously not realistic. Therefore more reasonable approach is to wax mold making, shell, melting and casting process costs (in this article called the front-end costs) according to the pouring of molten steel weight (called the casting weight) accounting, and then processing and auxiliary production costs (in this article called casting weight back cost) accounting. Pouring molten steel weight casting weight estimates manufacturing costs constitute in Table 1, the distribution of the mix of Figure 1 and Figure 2. Thus, the cost of the system shell and melting stage the proportion of total process costs more than 60%.
Two. The main factors affecting the differences in the cost of precision castings
Strictly speaking, different casting in the manufacturing costs of each process is not identical, but some aspects of differences is very small in accordance with the average level of accounting, we will be focusing on those casting cost factors. The main factors lead to cost differences in the casting process in the following areas:
(1). Process yield
Process yield, also known as yield, percentage of the actual casting weight accounted for pouring weight for concrete casting process yield is equal to the total weight of the castings on the same tree to account for a tree heavy percentage, and the casting structure and group tree program, which may vary within the range of 30-60%, and more generally in the range of 40-50%. Front-end cost and process yield the relationship
Per kilogram, the cost of casting the preceding =
Casting weight front-end cost of process yield per kilogram
Per kg of castings of the preceding costs and process yield is inversely proportional to the process yield, the lower per unit weight of castings preceding the higher the cost, and process yield, the lower the degree of impact is more significant. Pouring per kilogram of molten steel in the preceding costs 6 yuan per kilogram castings front-end cost of $ 13.33, when the process produced 45%; process produced castings when the rate of 30% front-end cost is 20 yuan / kg, higher than average process costs increased by 37.6% to 6.7 yuan, the total cost of 304 stainless steel castings rate about 17%; when casting the preceding process produced 60% cost is 10 yuan / kg, lower than the average level of 3.3 yuan, making the process cost reduction of 18.5%, and 304 stainless steel castings, equivalent to about 7% reduction in total cost;
Derivative of the cost of casting the preceding process yield can be drawn: the front-end costs of the process yield per kilogram castings impact process yield is inversely proportional to the square, when the process produced 45%, reduced by one percentage kg casting the preceding cost increase of 0.3 yuan, when the process produced 30%, increased by about $ 0.67 each to reduce the cost of casting of the preceding one percentage point per kilogram
This shows that the process yield on the cost impact is very significant. Like electrical engineering, power factor, reducing the process yield is equivalent to an increase of reactive power consumption. Course, the process yield is not as high as possible is not want another job got high, too high process yield will reduce the feeding ability of the gating system, resulting in feeding resulting from shrinkage or shrinkage defects; Some casting is irregularly shaped thin-walled castings by casting structure and group tree programs limit process yield is difficult to improve in the approved castings prices should take into account this important factor.
(2). System shell, the number of
Casting shape and structure of the different number of system shell vary. For example, the elongated hole or slot of the casting needs to be done twice or even three times the surface layer; general casting done enough for two backing layer, and relatively large castings may need to do three or more layers. The per kilogram cost of the casting system shell is about 5.9 yuan, which accounted for 67.8% of the cost of materials, fuel and power accounted for 23.9%, wages accounted for 13.3%. Consumption of zircon sand zirconium powder in a 4 yuan / kg of shell material costs account for about 63 percent, accounting for 42.7% of the cost of the entire system shell, silica sol costs account for about 12.2% of the cost of the system shell. Zircon sand zirconium powder is used in the surface layer.

The cutting characteristics of cast iron
In general, the higher the hardness and strength of cast iron, metal cutting, the lower, from the blade and tool life can be expected lower. The production of cast iron for metal cutting most types of metal cutting its generally very good. And structure of metal cutting, hard machining pearlitic cast iron its greater difficulty. Flake graphite cast iron and malleable cast iron has excellent cutting properties, but ductile iron is poor.
Encountered when machining cast iron main types of wear: abrasion, adhesion and diffusion wear. Mainly by the carbide abrasive, sand casting parameters and hard skin debris generated. BUE bond with wear at low cutting temperature and cutting speed conditions occur. Ferritic cast iron some of the most easily welded to the blade, but this can increase the cutting speed and temperature to overcome.
On the other hand, diffusion wear and temperature, generated at high cutting speed, especially when using high-strength cast iron grades. These grades have a high resistance to deformation capacity, resulting in a high temperature. This cast iron and tool wear and the role of the between, which makes some of the iron required ceramic or CBN (CBN) cutting tools in high speed machining, in order to get a good tool life and surface quality.
Generally required for the processing of a typical cast iron tool attributes are: high fever hardness and chemical stability, but also with the process, the workpiece and cutting conditions; requires cutting edge toughness, thermal fatigue, wear and edge strength. Satisfaction depends on cutting cast iron wear how to develop cutting edge: rapid thermal blunt means leaving the cutting edge cracks and gaps in premature fracture, broken parts, surface quality is poor, excessive waviness, etc. Normal flank wear, balance and sharp cutting edge is generally required to do.
Anti-carburizing low-carbon steel casting surface coating research and application..
Abstract: A new anti-carburizing low-carbon steel casting surface coating composition, production technology, performance characteristics and application examples. New anti-
carburizing paint can not only effectively reduce or eliminate low-carbon steel casting
surface by carbon, but also so that the coating is easy to peel, get no sticky sand, non-
porous, smooth surface of the casting.
Key words: low carbon steel; cementite; zircon powder; coating
CLC number: TG156 Document code: A Article ID :1000 -8365 (2010) 12-1551-04
Adopt resin sand process to produce low-carbon steel casting
s, steel castings prone to surface carburization shortcomings.
Carbon steel castings will reduce the cross-section shrinkage, elongation, deterioration of ductility and toughness. Low carbon steel casting
surface can lead to increased
hardness increases, machining difficulties, welding performance and other issues. Carbon-carbon stainless steel casting surface will increase its corrosion resistance decreased.
Anti-carburizing low-carbon steel castings is a research hotspot in recent years.
Low carbon steel casting surface by the main causes are: liquid steel casting and solidification process, the resin sand mold (core) work surface and paint resins and other
organic matter in the thermal decomposition products as CO, CO2, CH4, and a small amount of H2, there is a certain amount of pyrolytic carbon; these carbon by pyrolysis of
sand (core) / casting interface diffusion and penetration to the casting surface, leading to the casting surface by carbon.
Inferred: the sand (core) work surface coating layer can be formed at high temperatures a certain thickness of the dense sintered vitreous coating, for the prevention of low-
carbon steel surface by carbon should be a simple and effective method. To this end, we carried out anti-carburizing low-carbon steel castings for the development and
application of paint.
A low-carbon steel casting anti-carburizing paint composition design
New low-carbon steel castings mainly by anti-carburizing refractory coating binder, binder, solvent, dispersant and other additives SC (sintering additives, defoamers, wetting
agents, water-reducing agent, curing agent, leveling etc.) form.
1.1 fire-resistant powder
Low-carbon steel castings requires not only anti-carburizing paint coating sintering and sand requires a good anti-sticking effect. Accordance with the “anti-sticking coating
sintered strip of sand,” the theory, powder refractoriness not too high, the main consideration should be given its own or with fire-resistant powder coating and sand and between
the other components of the reaction between the substrate sintering at this time point close to the requirements of the sintering temperature of pouring alloy casting, the casting
process can generate a new phase or produce mild sintering, or completely molten, state or ceramic coating layer was the high viscosity of the glassy state, can resist the
penetration of liquid metal, and cooling easy to peel and after casting, get smooth surface of the casting, this is called sintering stripping paint coatings. Sintered refractory powder
coating stripping is generally complex, that is, from a variety of liquid metal casting in sintering temperature of each powder composition in a powder can be added on the basis
of the corresponding flux (or oxidant) to produce moderate to powder sintering and melting.
Accordance with the “anti-carburizing sintering coating” theory, sintering can paint just as the sand (core) layer of the working surface of the shield to block from the sand mold
(core) and C react with the liquid metal, or by gas or solid phase diffusion into the liquid metal, thus avoiding the steel castings produced by C and other defects.
Obtained at a high temperature high density, good shielding coating methods are:
(1) the use of sintering temperature lower than the metal pouring temperature 50 ~ 100 ℃, can be mild sintering of the refractory to form a dense coating.
(2) coating with refractory aggregate into some of the flux composition, moderate temperatures in the pouring melted to form a seamless layer of dense vitreous.
(3) use of fire-resistant fine-grained powder. General requirements powder 325 mesh particle size can all be over (40μm), in which
20% is appropriate.
Based on the above analysis, in order to simultaneously ensure low-carbon steel sand casting anti-carburizing and anti-sticking double effect, we use zircon powder as the
coating of fire-resistant binder.
The melting point of zircon powder with different impurities contained in the 2190 ~ 2430 ℃ fluctuated, but when in 1540 ℃ thermal decomposition of ZrO2 and SiO2, and
began to sinter (SiO2 of low melting point), has a certain self-sintering. Therefore, the sintering temperature of zircon sand and melting temperature between a wide temperature
range, which is conducive to it resulting in a sintered metal stripping liquid pouring, the casting surface is easy to clean. Zircon powder has been almost no infiltration of molten
metal or metal oxide, will help prevent the intrusion of liquid metal casting porosity, sand sticking to reduce mechanical defects. In addition, zircon powder under high
temperature performance is neutral to slightly acidic, and basic slag reaction is slow, chemical stability, high thermal, chemical sticky sand to prevent defects.
Zircon powder should have a reasonable size distribution. Particle size is too coarse, rough coating layer, and the suspension and the permeability is not good; too small, the
coating crack resistance is poor. The particle size distribution should be in the appropriate size range was greater dispersion in order to take full advantage of the thickness of the
particle interaction mosaic effect, be a dense coating of liquid metal to improve its anti-permeability and anti-carburizing capabilities. We use 325 mesh zircon powder as the
coating of the refractory base material,
Which the fine particles less than 10μm diameter greater than 15%. According to the structure of the casting conditions (weight, thickness, etc.) and production conditions
(material, pouring temperature, etc.) to adjust the sintering temperature of zircon sand range, plus also the coating amount of a flux. The flux after more than 1000 ℃ thermal
decomposition, resulting in a high-temperature stability, good chemical reducing gas. This reducing gas to avoid sand (core) / carbon interface material and casting liquid steel
contacts, to prevent the liquid interface layer absorption of carbon steel, which effectively reduce or eliminate the casting surface carburization.
1.2 binder
Cast coating is necessary to have a certain temperature strength, but also has good high temperature strength. According to this requirement, the binder should be used to heat the
organic binder and inorganic binder low-temperature composite application technology. However, the organic binder is generally carbon, the carbon bound to high-temperature
pyrolysis. Therefore, to ensure a certain temperature strength of the coating under the premise of the coating should minimize the amount of added organic binder, multi-use high-
temperature inorganic binder.
1.3 Solvent
Alcohol-based paint solvents commonly used ethanol, but ethanol combustion of common industrial poor in the winter, the coating does not burn completely. In order to
improve combustion performance, reduce production costs, can be added to methanol as an auxiliary solvent, but because of the human optic nerve there is a strong irritant, and
should not be more. Water-based paint solvents with ordinary tap water.
1.4 dispersed suspension stabilizer
We use a special aluminum silicate clay-based materials, the application of colloid chemistry of electrostatic steric dispersion stability theory, and in special composite
polymer electrolytes as dispersant and auxiliary has a variety of comprehensive reform of its appendages of treatment, develop new water-based and alcohol-based composite
dispersed suspension [1] (which was in 1998 obtained the national invention patent), respectively, for the production of water-based and alcohol-based coatings, has achieved
remarkable results. SC has the following characteristics of the new decentralized.
(1) use alcohol-based composite dispersed suspension without xylene lead to higher carbon content, can be activated only water, but the expansion in ethanol bentonite
considerable value.
(2) refractoriness up to 1650 ~ 1670 ℃, 300 ℃ higher than the bentonite above, fire resistance of the coating without adverse effects.
(3) 0 ~ 1200 ℃ shrinkage rate of 12.1%, only bentonite 0 ~ 1200 ℃ Shrinkage of 2 / 3, so that the coating will not crack defects.
(4) refractoriness and significantly improved crack resistance, to the maximum allowable in paint in the added amount can be as high as 12% (accounting for refractory powder
weight), adding the amount of range.
(5) play the role of the main components of dispersant coating also has the role of high-temperature binder; play the role of SC is also a major component of low-temperature or
high temperature adhesives, all have multiple roles.
After dozens of recipes for performance testing test paint and pouring comparison test, a new type of preferred anti-carburizing low-carbon steel casting surface water based
zircon powder and alcohol-based coating the best ratio range as shown in Table 1.
2 low-carbon steel casting anti-carburizing paint production technology and equipment
Currently there are paint processing equipment mixers, rolling machine and ball three. Mixers and fire-resistant powder paint rolling machine refinement of the role of weak,
poor mixing, processing time of up to several hours or even 10 hours, mixing paint and other suspension and brushing process performance is poor. Refinement of the powder ball
better, but not continuous production, and processing time is still for many hours, production efficiency is low, not suitable for mass production.
Supplemented by pre-mixing of the colloid mill mixer processing technology, is far more satisfactory paint production process. Stir the paint after the initial gear pump into the
colloid mill, due to the colloid transfer between the teeth and fixed teeth (the gap between 60μm or less) relative to high-speed rotation (speed up to 3000r/min), paint by the
strong suction , shear, friction and the role of high-frequency vibration (gear pumps also have these effects), can be effectively mixing, homogenization, dispersion and refinement,
and to generate new active surface of the powder (activated), to obtain excellent suspension, brushing, permeability and adhesion strength process performance.
With this mixer – Gear pump – the preparation of coating colloidal system, you can relax on the refractory raw material powder fineness requirements, but also mechanized
continuous production, and mixing short cycle, high efficiency (over traditional rolling machine equipment to improve several times ten times).
3 anti-carburizing low-carbon steel castings the main properties of coatings
Under the conditions of industrial production in the preparation of new low carbon steel casting surface carburization zircon powder against water-based and the main
properties of alcohol-based coatings are shown in Table 2.
New anti-carburizing water-based paint in almost no precipitation within 5h, 8 ~ 24h suspension of up to 98% ~ 99%, 1000 ℃ when the gas evolution is 16mL / g or less. New
anti-carburizing when the alcohol-based coating suspension at 8h to reach 95%, 1000 ℃ when the gas evolution is 19mL / g or less. Two kinds of coating and rapid heating at
1200 ℃ for 2min, when not crack, brushing and thixotropic index have a higher rate.
Paint brush index, is paint in the low shear rate (6r/min) and the apparent viscosity under high shear rate (60r/min) under the apparent viscosity ratio. It is characterized by a
coating of shear-thinning (or thickening) of, which is thixotropic structure. Brushing the higher the index, the better that paint brushing (brushing and effort, and good resistance to
flow, easy coating thickness).
Thixotropic coating rate, is the apparent viscosity η with mixing paint time rate of change, that time thixotropy. The calculation of (η0.5-η10) / η0.5 × 100, respectively, which
η0.5 and η10 paint stirring speed in 6r/min rotation 0.5min and 10min, the apparent viscosity. Thixotropic rate is higher, the better leveling coating, the greater the dilution range,
brushing of the better also.
4 Low carbon steel casting application effect of anti-carburizing paint
New low-carbon steel casting surface anti-carburizing zircon powder and alcohol-water-based paints, Wenzhou, in Zhejiang with a valve manufacturing company from furan
resin sand process to produce hard carbon steel parts to achieve a satisfactory result in the plant-volume applications more than a year.
The casting plant for the high-pressure check valve casting, made of type 304 and 316L stainless steel (U.S. ASTMV743 standard), single-piece weight 600kg, minimum wall
thickness of 50mm, maximum thickness 92mm. Modeling system using alkaline phenolic resin sand core; paint brush 3 times, respectively, alcohol, alcohol-and water-based,
alcohol-based paint before brushing twice ignited immediately after drying, the first three times backward brushing water-based paint bake oven dry for several hours; total
coating thickness of about 0.8 ~ 1.5mm.
Type 304 stainless steel high pressure valve 4.1 application results
304 (0Cr19Ni9) stainless steel high pressure valve of the original carbon content of molten steel is 0.06% ~ 0.08%, after pouring the casting surface layer requires control of
carbon content of 0.08 percent.
New low-carbon steel casting surface anti-carburizing zircon powder coating production and application results show that the permeability of the new coating, flow resistance
and crack resistance are well-coated, high strength, gas evolution is small; casting box to play when coated Most can be stripped into the film layer, smooth casting surface, sticky
sand and almost no pores, substantially increased the casting clearing efficiency, saving energy, reducing the labor intensity.
Table 3 lists the alkaline phenolic resin at the surface of the sand core, using the paint and coatings company in Shanghai production of zircon powder coating high-pressure
check valve type 304 stainless steel castings, in different locations of the chemical composition of spectral analysis results. From the table, when using this coating, the surface
layer of castings in carbon content of 0.074% controlled about 11% of the maximum rate of increase of carbon, carbon layer thickness ≤ 0.7mm, anti-carburizing effect is
remarkable; the use of a company in Shanghai zirconium British powder coating, casting surface up to 0.112% carbon, does not meet the production requirements, the highest
growth rate of 70% carbon, about seven times the paint, carbon layer thickness> 1.0mm; two kinds of paint on the casting of other composition had no effect.

Blow mold cooling and material selection
Most molds are designed to be blowing several independent cooling zones. Neck and bottom discharge most of its energy needs and cooling account for blowing mold design challenging and very important. Drilling cooling pipes installed in areas most in need of cooling. For better production control. Therefore asked the most effective cooling.
So the cavity is usually cutting machine. Copper alloy blow mold was also high heat resistance and good corrosion resistance. However, the information necessary to make blowing mold with high thermal conductivity and sufficient strength of the blade cut blank. Most of the current production of aluminum 7075 Blow Mold advanced alloys. As the metal machining performance. Its high cost, expensive, and three times its weight of aluminum, may be forming on the mechanical wear and tear is more serious. Blow molds are easy to use steel alloy welding repair method or the Mosaic law.
Because the strength and hardness of cast aluminum cutting blade blank mouth can not meet the requirements. Blow mold cast aluminum thermal conductivity than aluminum blow mold cutting badly. Cavity of the cut blank usually broken copper alloy or stainless steel inlay.
Operation with holes and shoulder area to be copper alloy or stainless steel inlays. The bottom and neck are inlaid with these two metals. Blow mold casting can also be cast copper alloy production. Cast steel chamber is relatively easy, Kirk alloy (zinc) steel castings can be produced on the master mold. Pouring into the mold cavity and to determine the size of the floor. As the intensity of the lack of alloy Kirk to cut the plastic. Because it is relying on pressure or gravity casting. Many of these cavity modes by the parent or steel production of fine ceramic blow mold parts.

Chilled cast iron and the characteristics of wear-resistant alloy cast iron
Chilled cast iron and cast iron wear-resistant alloy is commonly used in the production of wear-resistant materials. Chilled cast iron, also known as cold shock, it is placed in cold cast iron, in order to speed up the cooling rate of castings obtained. The typical chemical composition of chilled cast iron as: C content of 3% ~ 3.5%, Si content of 0.5% ~ 0.7%, Mn content of 0.5% ~ 0.7%, P content <0.4%, S content <0.07%. Chilled cast iron is characterized by occurrence of white part of the surface hardness and wear resistance greatly improved, remained within the gray tissue, to prevent the overall embrittlement. Chilling the surface hardness of HRC60 or so, calendar roll is an example.
Chilled nickel-chromium cast iron is also in this case. Nickel-chromium cast iron Chilled Ni content of 4%, Cr content of 1.1%, Ni refine the pearlite and graphite, increase strength and wear resistance of cast iron. Added strength of Ni can improve the heat. Quench hardness of nickel-chromium cast iron up to HRC60, used to make rolls.
High-temperature wear-resistant high chromium cast iron is cast iron, the typical composition of: Cr content of 22% ~ 25%, Si content of 1.2%, Mn content of 0.3% to 0.75%. Cr is added to improve the wear resistance of cast iron, because the Cr in casting a dense protective film formed on the surface Cr2O3. Cr is also generated by adding carbon to improve the hardness and strength of cast iron. High chromium cast iron used to make the work under high temperature above 800 ℃ wear pieces.
Used in drilling mud, is wear-resistant alloy cast iron Crl5Mo3 manufacturing, and its hardness up to HRC62, is the most difficult machining of metal materials.
