摘要
高炉喷吹煤粉可以使炼铁生产节焦降耗，改善高炉冶炼过程，而混合喷吹及大喷吹量是进一步发展高炉喷煤的主要方向。昆钢炼铁厂在原来混合喷吹的基础上，逐步提高喷吹煤烟煤配比，球磨机出力增加。高炉的技术经济指标得到了改善。
Pulverized coal injection technology is used in the blast furnace process,this technology can reduce the consumption of metallurgical coke,pig iron reduces the cost, smelting process is improved. In future,mixed and intensive coal injection technology will become the development direction.Based on mixed injection production practice of Kungang iron- coal injection was improved s production indexes were impro tep by step, output of ball ved. making plant, soft coal mill was increased, BF proportion of pulverized technical and economic
