2005年,邯钢通过技术进步和加强管理,促进了运行方式的系统优化,着力改善了影响综合效益的主要技术经济指标。炼铁入炉焦比由上年的399.9kg/t 降到378.9 kg/t,喷煤比由上年的124kg/t 提高到133.1kg/t,返矿率由上年的12.74%降到9.57%;轧钢综合合格率和综合成材率分别由上年的99.53%、97%提高到99.56%和97.06%。在同机型指标对比中,300m 3高炉入炉焦比、2000m 3高炉利用系
In 2005, through technological progress and strengthening management, Handan Iron and Steel accelerated the systematic optimization of operation mode and focused on improving the major technical and economic indicators that affect the overall efficiency. The ratio of ironmaking into the furnace dropped from 399.9kg / t in the previous year to 378.9kg / t, the coal-spraying ratio increased to 133.1kg / t from 124kg / t in the previous year, and the rate of return to ore fell from 12.74% in the previous year to 9.57 %; The comprehensive qualified rate of rolled steel and the comprehensive finished product rate increased from 99.53% and 97% of the previous year to 99.56% and 97.06% respectively. In contrast with the same type of indicators, 300m 3 blast furnace into the furnace coke ratio, 2000m 3 blast furnace utilization
