摘要
Abstract
Based on the analysis of converter slagging and limestone slagging, the key point of smelting control and the operation strategies during the entire limestone steelmaking process were proposed in this paper, combined with the research of the double-slag-ging process by lime. According to the production practice in Shijiazhuang Iron and Steel Company, the entire limestone steelmaking of special steel was conducted. In the results, the average C content of the molten steel after converter tapping is 0. 16%, and the aver-age P content is 0. 011%, which meet the requirements of special steel production. Compared with the entire lime steelmaking, the cost of entire limestone steelmaking is reduced by ¥2. 32 per ton molten steel. The results of the industrial experiment show that the entire limestone steelmaking can make good economic benefits, and has some promotional values.关键词
