摘要：

The solubility of chromium oxide in the CaO-CaF2 system has been determined at 1773K by equilibrating the flux with a CaO.Cr2O3 pellet at the oxygen partial pressure of 2.28 x 10(-7) Pa. The solubility of Cr2O3 varies from 0.80 to 1.28 mass% in the flux with increasing the CaO content from 15.6 to 20.6 mass%. In case of the dephosphorization of Fe-Cr-C melts with CaO bearing fluxes, the prevailing oxygen partial pressure of the system is controlled by the reaction between CaO and Cr2O3 forming CaO.Cr2O3. The phosphorus distribution ratio between Fe-Cr-C-satd. alloys and CaO-SiO2-CaF2 fluxes saturated with CaO.Cr2O3, CaO and 3CaO.SiO2 has been measured at 1573K. The phosphorus and chromium distribution ratios decrease with increasing chromium content of the metal from 1 to 13 mass%.
