摘　　要：对渣-钢脱磷反应影响因素进行了理论分析和试验研究。结果表明:磷在炉渣和钢水中的分配比随炉渣氧化性的增加而增加;在一定炉渣碱度范围内随着炉渣碱度的增加而增加,当碱度高到一定程度后,则随碱度的升高而下降;在一定的温度范围内随着温度的增加而增加,当温度高到一定程度后,则随温度的升高而下降。Theoretical analysis and experimental research on factors affecting dephosphorization between molten steel and slag are described in this paper. The results show that the phosphorus partition ratio of the slag-steel increases with the increase of oxidability, basicity of slag. In the condition of higher basicity of slag, the ratio decreases with the increase of slag basicity. As regard to the influence of temperature on the ratio, the ratio increases with the increase of temperature to some extent. In the condition of higher temperature, the ratio decreases the increase of temperature.
