摘　　要：介绍了马钢120 t转炉炼钢应用生白云石代替部分石灰和镁球进行少渣冶炼的工艺,分析了少渣冶炼对转炉吹炼过程、脱磷效果以及终点温度控制的影响。研究结果表明,在少渣冶炼工艺条件下,可以降低渣量,能够满足转炉脱磷效果和温度要求。转炉总渣料用量减少22.88 kg/t(钢),由此节约成本12.25元/t(钢);同时还可以降低金属料损失3.76kgt(钢),具有较好的经济效益。The less slag smelting process of using raw dolomite replacing parts of the lime and magnesium ball was intro- duced in 120 t converter of Ma steel. The influence of less slag smelting process on the effect of dephosphorization and the temperature control was analyzed. The results show that the less slag smelting process can reduce the quantity of slag and be able to meet the requirements of dephosphorization and the temperature control. The total dosage of slag charge can re- duce 22.88 kg/t（steel）, and the corresponding cost can save 12.25 RMB/t（steel）. At the same time, the metal material losses can be reduced 3.76 kg/t（steel）. So, it has good economic benefit.
