| 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;...

| Abstract: | 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. |
