The phosphorus partition between the unkilled liquid crude steel and the high basicity (CaO/SiO₂ = 4.2), basic oxygen furnace (BOF) slags with varying compositions of Al₂O₃, TiO₂, and MnO is studied at temperatures 1600 and 1650 °C. The tests are conducted in both “slag-to-metal” and “metal-to-slag” directions and for durations of 30 and 60 min. The measured results are compared with the values reported in literature and found to be in good agreement with some of them. It is found in the investigation of high-basicity BOF slags, that Al₂O₃, MnO, and TiO₂ lower the phosphorus partition. The phosphorus partition increases with increasing optical basicity. The phosphorus partition shows a maximum when the FeO content is in range of 25–30 mass%. The MgO content slightly increases the phosphorus partition.

液态粗钢与高碱度氧炉渣的磷分配

所述取消封杀液体粗钢和高碱度之间的磷分区（的CaO /二氧化硅₂  = 4.2），碱性氧气炉（BOF）的Al的不同组成的炉渣₂ ö ₃，的TiO ₂和MnO，研究在温度1600和1650 ℃。测试在“渣对金属”和“金属对渣”两个方向进行，持续时间为 30 和 60 分钟。将测量结果与文献报道的值进行比较，发现与其中一些值非常吻合。在高碱度转炉渣的研究中发现，Al ₂ O ₃、MnO和TiO ₂降低磷分配。磷分配随着光碱度的增加而增加。当 FeO 含量在 25-30 质量％范围内时，磷分配显示出最大值。MgO 含量略微增加了磷分配。
