从2005年11月,安钢1#2000m3高炉开始喷吹煤粉,高炉各项技术经济指标得到优化。但随着原燃料条件、高炉冶炼强度和操作技术水平的全面提高,原有的喷煤工艺和技术已不能满足高炉生产的需要,对喷煤及其控制系统进行技术改造势成必然。
From November 2005, Angang 1 # 2000m3 blast furnace started pulverized coal injection, blast furnace technical and economic indicators have been optimized. However, with the improvement of raw fuel conditions, blast furnace smelting strength and operation technology level, the existing coal injection process and technology can not meet the needs of blast furnace production. It is inevitable to carry out technical reform on coal injection and its control system.
