摘　　要：从热力学角度对CO_(2)用于不锈钢冶炼可行性进行了分析,通过热力学计算研究,发现在C含量不低于0.25%时,将CO_(2)用于不锈钢冶炼是可行的。建立了喷吹CO_(2)冶炼410S不锈钢工艺模型,该模型能够较好拟合实际应用CO_(2)冶炼过程。并通过70 t TSR炉工业试验结果进行验证。试验结果表明:CO_(2)用于不锈钢冶炼具有强化脱碳及减少铬烧损的效果,与原工艺相比,同期C含量降低0.011%,Cr含量提高0.144%。The feasibility of CO_(2) used in stainless steel smelting is analyzed from the view of thermodynamics.It is found that CO_(2) used in stainless steel smelting is feasible when the C content is not less than 0.25%.A material and energy model for 410 S stainless steel smelting by CO_(2) injection is established.The model can fit the practical CO_(2) smelting process well.The test results of 70 t TSR furnace in TaiShan stainless steel plant show that CO_(2) used in stainless steel smelting has the effect of decarburization and chromium preservation.Compared with the original process,the content of C decreases by 0.011%and the content of Cr increases by 0.144%.
