Abstract

PURPOSE: To produce low phosphorus steel, with omission of intermediate discharge of slag, by making self-fluxing dephosphorizing agent of specific composition containing CaO as a main component, and by adding the agent in an amount that the basicity of slag after blowing may be more than 5, the dephosphorizing agent being used for refining cast iron or steel.
