【摘要】 通过对不同熔剂、不同处理方法的热力学计算比较得出最佳铁水预处理顺序为:预处理脱硫→预处理脱硅、脱磷。对不同处理容器、不同处理方法的动力学条件比较得出预处理容器应选定:铁水包KR脱硫,专用转炉脱硅、脱磷。对铁水预处理的操作成本进行比较分析得出:脱硅、脱磷应选择专用转炉同时进行,脱硫应选择KR(CaO作脱硫剂)法。新建钢厂最佳铁水预处理模式确定为:高炉铁水→铁水包KR(CaO作脱硫剂)法脱硫→专用转炉脱硅、脱磷。更多还原

【Abstract】 The optimal order of the hot metal pretreatment achieved by thermodynamic calculation and comparison of different flux and pretreatment methods is hot metal desulphurization-desiliconizaton and dephosphorization.The pretreatment containers determined by comparison of the thermodynamic conditions for different flux and different pretreatment methods are as follows: ladle for desulphurization by KR and converter for desiliconization and dephosphorization exclusively.It’s concluded by comparison analysis of the operation cost for hot metal pretreatment that special converter be selected to carry out dssiliconization and dephosphorization simultaneously and for the purpose of desulphurization KR method(CaO used as the desulphurizer) be adopted.The optimal hot metal pretreatment mode for the newly built steel-making plant is determined to be hot metal desulphurization in ladle by KR method(CaO as desulphurizer) and desiliconization and dephosphorization in converter.更多还原
