1998年炼铁厂加大“远学邯钢,近学炼钢”力度,通过对比分析,找差距,找原因,达到挖掘增产节约潜力。1月至9月两座高炉平均煤比达53kg/t,与去年同期相比,吨铁煤比提高26kg/t,喷煤总量30042t,煤焦置换比按0.7计算,创经济效益288万元;随着喷煤量的增加,改善了高炉冶炼行程,入炉焦比明显降低;1998年1至9月高炉平均入炉焦比为549kg/t,比去年同期降低了88kg/t。为了实现公司扭亏目标,公司将高炉喷煤比指标作为重点考核内容,分别列入炼铁
In 1998, the ironworks stepped up its efforts to “make great efforts in Handan Iron and Steel, and steelmaking in recent years.” Through comparative analysis, finding the gaps and finding the reasons, the potential for increasing production and saving was reached. January to September average blast furnace coal ratio of 53kg / t, compared with the same period last year, iron and coal increased by 26kg / t, total coal injection 30042t, coal replacement ratio calculated by 0.7, the economic benefit of 2880000 Yuan; with the increase of coal injection, improved blast furnace smelting schedule, into the furnace significantly reduced the coke ratio; January to September 1998 average blast furnace into the coke ratio of 549kg / t, down 88kg / t over the same period last year. In order to achieve the company’s goal of turning losses, the company will blast coal injection than the index as a key assessment content, were included in the iron and steel
