摘要
经过1997年1～3月的工业试验,1997年4月至1998年4月,在喷煤系统没有改进的情况下,包钢炼铁厂通过严格控制煤粉挥发分、扩大煤粉粒度、严格管理,成功地把烟煤配比由1996年的9.06％提高到了22.08％,使高炉各项技术经济指标得到改善。
Through the industrial test during January-March of 1997,the bituminous coal rate was raised from 9.06% in 1996 to 22.08% during April of 1997 to April of 1998 by strictly controlling the volatile content of mixed coal,enlarging coal size,and improving management at Baotou Iron & Steel Co.. The blast furnace production indexes were raised .
