对邯钢5号高炉“经济炉料”条件下的生产实践进行了总结。针对高炉原燃料条件变差和处于炉役后期的实际情况,通过对原燃料的改善和合理利用、操作制度的适当调整,以及管理制度的逐步完善,生产指标依然达到了开炉以来的最好水平,2014年12月5号高炉利用系数2.622,焦比322.9 kg/t,燃料比502.5 kg/t,一级品率99.8%,吨铁原燃料成本扣除原燃料价格影响较2014年降低30元/t。
The production practice of Handan Iron and Steel No. 5 blast furnace “economic charge” conditions were summarized. In view of the fact that the condition of the raw fuel in the blast furnace is getting worse and in the later stage of the furnace service, the production index still reaches the best since the furnace was started by improving and rationalizing the utilization of raw fuel, proper adjustment of the operation system and gradual improvement of the management system December 5, 2014 Blast furnace utilization factor 2.622, coke ratio 322.9 kg / t, the fuel ratio 502.5 kg / t, the first grade product rate 99.8%, the cost of tonne iron raw material deducting the impact of raw fuel prices lower than 2014 30 yuan / t.
