Heredity of the Structure and Properties of Grey Cast Iron Melted on a Basis of Steel Scrap

Abstract:

In this paper are presented the results of researches, obtained during cast iron melting on basis of steel scrap and a carburizer (without pig iron in solid charge). In the process of carburization, there were used the carburizers such as anthracite, natural and synthetic graphite, petroleum and cupola coke, as well as charcoal. The grey cast iron was produced, for which quantitative analysis of graphite precipitations was performed. It was noticed that in case of using anthracite as carburizer, the smaller graphite precipitations were obtained. In authors’ opinion they are consequences of anthracite structure, consisted of fine graphite flakes and phenomenon of charge materials features’ transfer into melted alloys (structure heredity).
