Abstract

The slag inclusion and gas hole defects were generated easily in EPC steel castings. The source

shape distribution and position where slag inclusion easily occur were analyzed. According to the filling behavior of molten steel

influence of the turbulent flow and wall attachment effects of filling molten steel on formation of slag inclusion were approached. Based on the thermodynamics and kinetics

the forming and floating mechanism of the slag inclusion in EPC steel castings were described. The approaches and ways of eliminating slag inclusion in EPC steel castings were presented.
