摘要: 介紹了硫容量的理論背景、KTH模型計算硫容量方法以及硫平衡分配比的計算方法,分析了影響硫平衡分配比的因素。結果表明：硫平衡分配比隨鋼液中%C,%Al的增加而增加,隨鋼液溫度的增加而降低；硫容量隨鋼液溫度增加而增加,隨渣中(%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.
