Abstract

Abstract

The reasonableness of direct alloying with chrome ores is discussed with thermodynamical analysis as well as the influencing factors, such as the burden of chrome ores, basicity of slag and reductants. The results of experiments have shown that the basicity of slag should be around 1.5 and the chrome ore burden was limited up to 30% of Cr₂O₃ in slag. Carbon was used as reductant first and then silicon to continue for better metallurgical effect.
