基于对宝钢2号高炉炉缸死料柱焦炭、渣铁等物相的取样分析结果,建立了表征死料柱透液性和炉缸活性的指数L。L与2号高炉炉底温度变化具有很好的对应关系,可用于高炉生产过程中对炉缸活性状态进行判断、监视和管理,并提出了改善炉缸活性、控制炉缸侧壁侵蚀的技术途径和措施。
Based on the sampling and analysis of the coke, slag iron and other phases of the blast furnace column of Baosteel No.2 blast furnace, the index L for characterizing the liquid permeability of the dead column and the hearth activity was established. L has a good correspondence with the furnace bottom temperature of No. 2 blast furnace, and can be used to judge, monitor and manage the activity state of the hearth in the production process of the blast furnace. Techniques for improving the activity of the hearth and controlling the side wall erosion of the hearth Ways and measures.
