摘要
介绍了宣钢一炼铁厂对比使喷煤工艺进行的改造。增加了配加烟煤的配煤系统，实现了混合喷吹３０％烟煤，达到了降低焦比使煤焦置换比提高０．１的效果。
Coal injection process in No. 1 Iron Works of Xuanhua Iron and Steel Company has been improved with a new coal--burdening system built to add bituminite into anthracite. A good result has been gotten that the ratio of bituminite in mixing coal injection can reach to 30% and coal--coke replacing ratio can be increased by 0. 1.
