| 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。

| Abstract: | The industrial experiment of direct alloying by manganite self-reducing briquettes was carried out in 100 t 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 15 kg/t, the average temperature drop 18 ℃. ,and that will not affect the normal smelting of the converter. |
