Abstract

CaO-CaF₂ system was examined with respect to dephosphorization of steels with high chromium content. The emphasis was on the effect of chromium oxide on slags phosphate capacity.
Phosphorus distribution between stainless steel and CaO-CaF₂ flux was investigated under different oxidizing potential and temperature. It was found that chromium oxide formed in the oxidizing dephosphorization process, decreases phosphate capacity of slag and significantly affects steel dephosphorization.
