摘　　要：分析了转炉钢水终点残锰量的影响因素,针对达钢80t转炉生产实际数据,研究表明终点残锰量与铁水Si、Mn含量和钢水终点C含量成正相关,并建立了达钢80t转炉钢水终点残锰量的数学模型。将该模型用于现场检验,其预估值与分析值的偏差值≤0.01%的准确率达到88%,可以把预估残锰值用于配加含锰合金计算,达到减少合金加入量,降低成本的目的。This paper analyzes the influence factors of residual manganese content in molten steel by steel converter.According to the 80 tconverter actual production data of dagang,research shows that residual manganese is positively related to the amount of Si,Mn content in molten iron and C content in molten steel.A mathematical model of molten steel residual manganese content in dagang＇s 80 tsteel converter was set up.Using the model for on-site testing,the accuracy rate of deviation value≤0.01% between estimate value and analytical value has reached up to88%.The estimate residual manganese value can be used to calculate the amount of manganesecontent alloy to add to the steel,achieving the purpose of reducing the alloy addition amount and costs.
