Q:What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?: Corundum sand: the main mineral composition is corundum alpha -Al2O3, used for investment casting, ceramic mold casting shell materials. The olivine sand: the main mineral composition of olivine (MgFe) 2SiO4, used in cast iron, non-ferrous alloy castings and high manganese steel casting molding sand and the core sand. Silica resources in nature resources, but suitable for casting with high SiO2 content of natural silica sand is not too much. Since 1951, China has carried out a general survey of the casting sand resources in the territory, but mainly limited to the main traffic lines and major industrial cities. Survey results show that Chinese can be used for natural silica sand casting is very rich in resources, a wide range of distribution. Inner Mongolia Zhelimumeng, natural silica sand reserves amounted to hundreds of millions of tons, the particle shape close to the circular, the content of SiO2 is about 90%. Fujian, Jinjiang Dongshan sea sand, the content of SiO2 is 94 to 98%, with a low volume of mud, are good natural silica sand. Are Duchang, Yongxiu Jiangxi County Xingzi, a large number of Quaternary lacustrine deposition of silica sand, the content of SiO2 is about 90%, low iron content, alkaline oxide less, uniform size, is a good lake sand. Guangzhou, Hunan and other places have abundant easily broken weathered sandstone, processing artificial silica sand, the content of SiO2 in more than 96%, can be used for the production of steel castings. Jiangsu Nanjing red sand, sandy mud pure, moderate, strong permeability, good viscosity, high silica content, less water, fine particles, pulls out the casting is smooth, stable quality, can be made of cast iron and non-ferrous metal parts of the sand and core sand

Q:Explain the heat treatment effect of casting parts, forging parts and welding parts: 2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.

Q:Why do cheap cars like stamping parts instead of casting parts?: Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute. The purpose of forming processes is to allow the sheet to undergo plastic deformation without breaking the billet and to make the desired shape and size. In actual production, a variety of processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning, and straightening are the main types of stamping machines.

Q:ZGMn13 casting parts processing, with what knife head good?: The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger, its surface wear resistance is high; the two is with the gradual wear of surface hardening, the hardening layer is continuously formed new if you have suggestions, processing, plasma cutting or flame cutting try

Q:What is the difference between forging parts and casting parts?: The casting parts are low in cost and short in production period. Because the molten iron has good flow properties, complex shapes can be formed. But because there may be sand holes, pores, shrinkage holes and other defects, the quality is unstable, easy to produce many defects, mechanical properties are not forged well, thus affecting the service life.

Q:For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified: According to the grade of the parts, according to the relevant standards, the regular drawings will be noted in the technical requirements of the parts.

Q:our factory now produces steel castings in the use of polishing directly after spraying processing, but the powder sprayed 15But the spray powder touched off what is the reason we are not very strict requirements not only need to peel off bubbles can also, because our products are steel castings so we use steam hole sludge put on. Do not know if this spray treatment has no effect to thank friends with us!: Usually after rusting,Did you peel it?If it isNeed to do film processingIf notPlease look for the coating factoryBetter paint (such as epoxy ester, etc.)

Q:How to cast iron and wrought iron collocation: So we can only watch and ear distinction: 1, see: Iron fracture is rough, showing a bead (for the sake of coarse grain iron), and wrought iron fracture is generally more smooth; if this is a new fracture, but also to see the dark and shiny born iron wrought iron pig iron is bright; the fracture is generally irregular, because it is very brittle, mostly is interrupted, (which is processed, it is very flat and wrought iron) must not be interrupted, mostly by certain way processed separately, so the fracture is generally neat; if the fracture is that is cutting, wrought iron, iron is not cutting; iron surface will not have pores, familiar iron porosity; if a piece of iron is a significant deformation (bending) that is wrought iron because of poor plasticity It doesn't have to be so deformed, it's really bent, or it's broken, or it's obviously cracked, and it doesn't bend very much. There are some details that can not be made clear. It is necessary to have some experience.

Q:Is 316 casting better than 304 casting?: The degree of difficulty in the process of casting depends mainly on the structure, precision requirements, and hardness of the casting. It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing

Q:The cause of fracture and why there is no toughness: This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
