Key points of foundry technology of coated sand (1)
/in Castings, Producing grinding ball process /by Sara WuResin coated sand casting has a long history in the field of casting, and the output of casting is quite large, but there are many problems when using resin coated sand casting to produce precision steel castings, such as sand burn, cold shut, and air hole. How to solve these problems remains to be explored. […]
Characteristics and application of high chrome wear resistant cast iron
/in Castings /by Sara WuHigh chrome cast iron containing 12.30% chrome and 2.4-3.6% carbon can be highly alloyed and heat treated to obtain martensite or austenite or mixed matrix and special carbides of chrome. This particular carbide is a hexagonal system of Me7C3 with hardness as high as HVL200. 1600, much higher than the cementite type of carbides and common mineral […]
Reasonable carburizing agent was selected to improve the casting tensile strength
/in Castings /by Sara WuThe microstructure and properties of cast iron depend on the microstructure and quality of raw materials to a great extent. The use of recarburizer is very important, especially for cylinder block and head castings with high densification requirements.
