青钢高炉渣中适宜镁铝比的探讨与实践 1,222 张宏星,安秀伟,王东 12 (北京科技大学;青岛特殊钢铁有限公司) 摘要: 通过理论分析结合青钢新老厂区多年现场实际生产情况,对高炉渣中合理镁铝 比进行了探讨,结果显示高炉适宜的镁铝比很大程度上取定于高炉的原燃料条件和操作 33 500m0.651800m 环境。青钢原燃料条件下,老区高于适宜的镁铝为左右,新区高炉 0.50 适宜的镁铝比为左右,后期随冶炼条件的改善,可继续降低。 关键词 高炉渣物理热镁铝比粘度 Exploration and investigation to Suitable for MgO-AlO 23 Ratio of Blast Furnace Slag of Qingsteel 1,222 ZHANG Hongxing AN Xiuwei Wang Dong (1.University of Science and Technology Beijing2.Qingdao Special Steel Co., Ltd) ; Abstract Theoretical analysis combined with the years of actual production condition in the new district and the old district of Qingsteel, showed that the suitable for MgO-AlO ratio of blast furnace slag much depended on the current conditions of 23 raw material, fuel and the blast furnace operation. At the conditions of Qingsteel, the suitable for MgO-AlO ratio of blast furnace slag is about 0.65 for the blast furnace 23 33 of 500 min the old district, and is about 0.50 for the blast furnace of 1800 min the new district, which can be continued to reduce, with the improvement of operating condition.
