炼铁厂今年开展技术攻关36项,到6月底止完成或达标的有17项,主要有:2号炉护炉强化生产,系数达1.836t/m ~3·d;炉料结构优化,操作优化;提高喷煤量已达76kg/tEe;减少熔剂消耗到16kg/tEe;焦炭整粒;2号炉槽下过筛及除尘;2号高炉上料系统改进;3号高炉炉喉灌浆等。通过技术攻关,与去年相比,降低了焦比 Iron and steel to carry out technical breakthroughs this year 36, until the end of June to complete or achieve the standard of 17, are: 2 furnace fortified production, coefficient of 1.836t / m ~ 3 · d; charge structure optimization, operation optimization ; Improve the amount of coal injection has reached 76kg / tEe; to reduce flux consumption to 16kg / tEe; coke whole; soot and dust removal furnace No. 2; No. 2 blast furnace feeding system improvement; No. 3 blast furnace throat grouting. Through technical research, compared with last year, reducing the coke ratio
