Calculation and analysis of sulphide capacity and sulphur partition ratio

摘要: 介绍了硫容量的理论背景、KTH模型计算硫容量方法以及硫平衡分配比的计算方法,分析了影响硫平衡分配比的因素。结果表明：硫平衡分配比随钢液中%C,%Al的增加而增加,随钢液温度的增加而降低；硫容量随钢液温度增加而增加,随渣中(%Al₂O₃)/(%CaO)比值的增加而降低。

Abstract: The theoretical background of calculating sulphide capacity by the KTH model and the method of calculating sulphur partition ratio were introduced. Some parameters that affect the sulphur partition ratio were studied. The result showed that (1) the sulphur partition ratio increased with the increase of %C, %Al and decreased with the increase in temperature; and (2) the sulphide capacity increased with the increase in temperature and decreased with the increase of % Al₂O₃/% CaO in the slag.
