摘要

The phosphorus partition (L_P) and phosphate capacity (C_(PO_4~(3-)) were measured for slags in the CaO-SiO_2-MgO-Fe_1O-(MnO-Al_2O_3-TiO_2-P_2O_5) system over temperatures representative of basic oxygen steelmaking. The measured L_P values were found to be in good agreement with those predicted from the model of Assis ef al. The oxygen potential of the slag-metal systems studied was also evaluated and used in combination with the measured L_P to calculate the C_(PO_4~(3-)) of the slags. Capacity values in the range of 7.77 × 10~(16) to 4.27×10~(19) for temperatures 1 550℃ to 1 700℃ were obtained. Correlations of C_(PO_4~(3-)) with common measures of slag basicity (v-ratio and optical basicity) were sought and reported. Consistent with other researchers it was found that the L_P and C_(PO_4~(3-)) increased with increasing slag basicity and decreasing temperature.
