高炉型渣脫硫的离子理論
, PP. 127-141
Abstract:
根据新提出的碱度指标,对低碱度高炉型渣的离子结构作了假定。利用前文提出的、适用于各种碱性炼钢型渣的硫分配比公式(％S)/[％S]=32L_Sf_S/γ_(Fe~(2+))γ_(S~(2-))·(∑n+∑n-)/n_(FeO)对Hatch和Chipman,Taylor和Stobo以及等的饱和碳铁液和高炉型渣平衡实验数据进行处理分析,得出Igγ_(Fe~(2+))γ_(S~(2-))=-53.5N_(O~(2-))+2.12。进一步计算证明了该硫分配比公式也适用于一般的低碱度渣。对碱性炼钢型渣适用的、关于FeO含量对脱硫作用的规律证明了也适用于低碱度渣。将f_S与(％S)/[％S]合并考虑,则(％S)/α_S基本上不受温度和铁液成分的影响。
