| Abstract: | Production of compound cast iron with scrap steel recarburization in place of conventional pig iron can improve the quality of castings and reduce the cost of production. This paper introduces the selection and properties of recarburizers, analyzes the influence of melting speed and temperature, chemical composition of molten iron, stirring of molten iron, addition of recarburizer and the adding process on the absorptivity of recarburizer, and studies the trend of structures and properties of compound iron with the application of scrap steel recarburizing process. |
