In recent years, steel casting foundries have made some thin-wall castings, and when they began mass production, the rejection rate was very high because of the shrinkage hole problem. Later, according to the experience of unsuccessful casting in the past, for thin-walled castings, steel casting fou......
Read MoreThe carbon content of gray cast iron is relatively high, and it can be regarded as a carbon steel matrix with flake graphite. According to the different matrix structure, gray cast iron can be divided into three categories:1. Ferritic matrix gray cast iron;2, pearlitic ferritic matrix gray cast iron......
Read MorePickling is an indispensable step in the production of precision casting, which is a process in which the precision casting parts are immersed in an acidic solution and a variety of oxidizing substances and rusts on the surface of the steel are removed by chemical reaction. So, how is the precision ......
