经实际验证的计算表明,在炼铁时使用一吨转炉渣能节约300～480公斤铁矿石,530～620公斤石灰石,110～120公斤白云石,140～180公斤锰矿石和80～120公斤焦炭。为了降低焦比和提高生产率,要求加入烧结料和高炉炉料中的转炉渣粒级范围要小,加入烧结料的应为0～10毫米,加入高炉炉料的应为10～40毫米。这就要求在有氧气转炉炼钢厂的企业建立破碎分选系统。在高炉炉料中用转炉渣取代生石灰石是保证节省焦炭的主要因素。在这种情况下,高炉渣量可能增加10～30公斤/吨(视转炉
The verified calculation shows that using one ton of converter slag during ironmaking can save 300-480 kg of iron ore, 530-620 kg of limestone, 110-120 kg of dolomite, 140-180 kg of manganese ore and 80-120 kg of coke . In order to reduce the coke ratio and increase the productivity, it is required to add the sintering slag and blast furnace charge converter slag particle size range is small, adding sintering material should be 0 to 10 mm, adding blast furnace charge should be 10 to 40 mm. This requires the establishment of crushing and sorting systems in enterprises with oxygen converter steel mills. Replacing raw limestone with converter slag in the blast furnace charge is a major factor in saving coke. In this case, blast furnace slag may increase 10 ~ 30 kg / ton (depending on the converter
