摘　　要：在100 t顶底复吹转炉上使用锰矿自还原压块进行直接合金化工业试验中,并对冶炼过程中钢水和炉渣进行取样分析。研究表明:在采用锰矿自还原压块进行转炉直接合金化时,金属锰的收得率平均为65.17%,但有较大波动;提高转炉终点[C],减少转炉渣量,降低炉渣氧化性可有效提高金属Mn的收得率;当按15 kg/t配入团块,转炉终点温度平均降低18℃,未对转炉的正常冶炼造成影响。The industrial experiment of direct alloying by manganite self-reducing briquettes was carried out in 100t top botton combined converter,and the steel and slag were sampled and analyzed during smelting.The results show that the average yield of manganese is 65.17%,but it fluctuates greatly when the manganite ore self-reducing briquettes was added in the converter.Improving the end point of [C ],reducing the amount of slag and reducing the oxidation of slag can effectively improve the yield of manganese.When the adding amount of the briquettes was 15kg/t,the average temperature drop 18℃,and that will not affect the normal smelting of the converter.
