The mechanical properties of cast iron are related to the structure of the matrix and the morphology of graphite, and the matrix structure has a certain influence on the mechanical properties of gray cast iron. For cast iron foundries, gray iron castings have many benefits such as good casting perf......
Read MoreThe shrinkage rate of stainless steel is much larger than that of cast iron, so in order to prevent the defects of shrinkage and shrinkage of stainless steel castings, the foundries have adopted riser and cold iron and subsidies and other measures in the casting process. So what are the difficultie......
Read MoreIn 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......
