72 ferrosilicon block for casting
is an iron-silicon alloy with a silicon content of about 75%. Its chemical composition varies depending on the production process and use. The content of silicon element in ferrosilicon has an important influence on the casting performance. At the same time, other trace elements such as aluminum and calcium also play an important role. Through inoculation treatment, the pores and cracks inside the casting can be reduced and its density and integrity can be improved.
