包钢高炉冶炼含碱金属(K_2O+Na_2O)相当高的白云鄂博矿石,入炉碱负荷逐年升高.1981年以来,碱负荷高达10～13公斤/吨铁,给高炉冶炼带来一系列困难.本文应用数理统计方法,查明渣铁中某些成分与炉渣含碱量之间的相关关系,从中引出规律,以便从高炉操作制度入手,有效地控制碱害,防止高炉结瘤.作者对包钢2~#高炉1981年8月至1982年8月(1981年12月～1982年3月除外)共九个月的242组正常生产数据进行数理统计,找出了炉渣含碱量与渣铁某些成分之间的相关关系,据此适当调整,可以保证高炉正常冶炼,生产合格生铁.
Baotou blast furnace smelting of Bayan Obo ore containing alkali metal (K 2 O + Na 2 O) is relatively high, the load into the furnace increased year by year since 1981, the alkali load of up to 10 ~ 13 kg / t iron, blast furnace smelting brings a series of difficulties In this paper, mathematical statistics were used to find the correlation between some components of slag iron and alkali content of slag, leading to the law from blast furnace operating system to effectively control alkali damage and prevent the nodules from blast furnace. 242 sets of normal production data of Baoshan Iron and Steel 2 ~ # blast furnace from August 1981 to August 1982 (except December 1981 ~ March 1982) for a total of nine months were analyzed by mathematical statistics to find out the slag alkali content and slag The correlation between certain components of iron, accordingly adjust accordingly, can guarantee the normal smelting blast furnace, the production of qualified pig iron.
