Zusammenfassung:CaO-CaF sub 2 system was examined with respect to dephosphorization of steels with high Cr content. The emphasis was on the effect of chromium oxide on slags phosphate capacity. Phosphorus distribution between stainless steel and CaO-CaF sub 2 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.
