炉料结构是否合理将直接影响高炉焦比及其它技术经济指标。目前,高炉炉料结构有四种:烧结矿配生矿、100%烧结矿、100%生矿、碱性烧结矿配酸性球团矿。我厂3~#高炉(300m~3,1000m~3/min电动风机供风)自1985年11月份投产到今年3月份,炉料结构基本上是70～75%烧结矿,配30～25%生矿。高炉生产水平:利用系数低,焦比高,而且不稳定,最长稳定周期不到一个月;有的月份产量高,但是焦比也比 Burden structure is reasonable or not will directly affect the blast furnace coke ratio and other technical and economic indicators. At present, there are four kinds of blast furnace charge structure: sinter with ore, 100% sinter, 100% raw ore, alkaline sinter with acidic pellets. I plant 3 ~ # blast furnace (300m ~ 3,1000 m ~ 3 / min electric fan for the wind) from November 1985 put into operation in March this year, the charge structure is basically 70 to 75% sinter, with 30 to 25% of Health mine. Blast furnace production level: low utilization factor, high coke ratio, and unstable, the longest stable period of less than a month; some high yield, but the coke ratio than
