一、高碱度烧结矿生产燃耗增加原因为了改变我厂高炉熟料比低(30%～40%)焦比高(800公斤/吨铁)、产量低的落后状况,从一九七八年四月起,我厂两台24平方米烧结机开始生产高碱度烧结矿(R=2.5～3.0)。几年来高炉使用效果表明:高炉配加35%～40%高碱度烧结矿,可 First, the increase in the production of high-basicity sinter burn reason In order to change my factory blast furnace clinker ratio (30% ~ 40%) high coke ratio (800 kg / ton of iron), low output of backward conditions, from 1978 In April of each year, two 24-square-meters sintering machines of our factory begin to produce high alkalinity sinter (R = 2.5-3.0). Blast furnace over the years the use of results show that: blast furnace with 35% to 40% of high alkalinity sinter can be
