- Q: What's the effect of casting copper?
- In general cast iron, the mass fraction of copper below 3% - 3.5% can increase the hardness; but when the cast iron has a tendency to chill, or when there is a hard point of free carbides, the addition of copper decreases the hardness.Copper can be used to improve the wear resistance, abrasion resistance, and shock absorption of cast iron, so it is often used in the manufacture of sliding friction iron castings, such as drilling machine spindle, automobile and tractor, valve tappet, etc.. But in white cast iron or chilled cast iron, adding copper does not make any improvement in its abrasion resistance.Copper for certain heat resistant cast iron and austenitic cast iron can increase the heat resistance and corrosion resistance, copper - chromium composite alloy to prevent oxidation under high temperature in the atmosphere from the skin effect is particularly effective, heat resistance and corrosion resistance of austenitic cast iron containing many mass fraction of 4% ~ 7% copper.
- Q: Explain the heat treatment effect of casting parts, forging parts and welding parts
- The three methods of metal processing have one thing in common. They are hot working, which are different in temperature and range of processing. Ductile cast iron is widely used because of its brittleness and poor impact. Heat treatment of cast iron usually adopts the annealing process, reduce the casting effect: 1 because of the internal stress caused by the thermal expansion and contraction, reduce the deformation after machining, decrease surface hardness, improve machining conditions;
- 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: Casting parts have poor surface finish. What sand is used to make them?
- Manual coal dust, clay sand is a little worse. Mechanical styling is not bad either.
- Q: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
- Hot galvanizingGenerally 0.06 mm or more
- Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
- Our country has a national standard for casting tolerance levels. This national standard applies to you in malleable iron, grey cast iron, and ductile iron.
- Q: How to solve casting defect casting?
- Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
- Q: What's the cause of the choking of the casting?,
- Causes of choking fire:1., casting material in the pouring of gas;
- 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: How can the casting be free of trachoma?
- Measures for the prevention of trachoma in castings:1, sand compaction to high, paint two times;
