摘　　要：针对电炉炼钢的成本、电耗、钢水洁净度及可浇性的控制问题,对三种工艺路线进行了对比。分析认为：不经过LF和RH的工艺路线的生产成本最低,吨钢冶炼工艺成本约为70~75元,电耗为50~55 kWh,但钢水洁净度控制较差,钢中w（T.O）为35×10-6~45×10-6,夹杂物等级为B类不大于2.0级,Ds类不大于1.5级;含RH的工艺路线的生产成本相对偏高,吨钢冶炼工艺成本约为90~100元,电耗55~65 kWh,但钢水洁净度控制较高,钢中w（T.O）为20×10-6~30×10-6,夹杂物等级为B类不大于1.0或1.5级,Ds类不大于1.0级。Focused on controlling of cost,power consumption,cleanliness and pourability of steelmaking in electric furnace,three process routes to produce low-carbon Si-Al killed steel are compared in this paper.The first process route without LF and RH has the lowest cost（about 70～75 Yuan per ton of steel）,its power consumption is about 50~55 KWh,but the cleanliness of steel is poor,w（T.O）35×10-6 ~ 45×10-6,inclusion ≤ 2.0 and ≤1.5 in Class B and Class Ds,respectively.The third process route with RH has the high cost（about 90~100 Yuan per ton of steel）,power consumption is about 55~65 KWh,but the cleanliness of steel is better,w（T.O）20×10-6~30×10-6,inclusion ≤1.5 and ≤1.0 in Class B and Class Ds,respectively.
