西钢1号高炉有效容积为100m~3,于1996年8月上旬炉况频繁悬料、崩料,先后采取倒装加净焦洗炉,效果一般;至9月中旬高炉严重结瘤,采取炸瘤的方式,炉瘤才被彻底地清除。前后经历一个半月之久,多耗焦炭500t,影响产量1000t左右,经济损失严重。 1.高炉结瘤概况进入8月份雨季以来,由于土球矿含粉量大(约25%),导致高炉料柱透气性变差,8月3日烧结矿碱度波动大,波动范围在1.60～2.12倍之间。由于烧结扩碱度(考核碱度为1.70±0.10倍)中下限很少上限居多,导致土球团矿(考核碱度为≤0.30倍)小料批配量由350kg/批提高到500kg/批,但仍持
The effective volume of blast furnace No. 1 in XISCO is 100m ~ 3. In the early August, 1996, the furnace condition frequently hangs and collapses. Blast the way, the stove was completely removed. Before and after going through a month and a half, more consumption of 500t coke, affecting the output of about 1000t, serious economic losses. 1. Known nodulation of blast furnace Since entering the rainy season in August, due to the large amount of dust (about 25%) in the earth mines, the gas permeability of the blast furnace column becomes worse. On August 3, the basicity of the sinter fluctuated greatly and the fluctuation range was 1.60 ~ 2.12 times between. As the sintering degree of alkalinity (test alkalinity of 1.70 ± 0.10 times) the upper and lower limits of the upper limit is not large, resulting in soil pellets (test alkalinity ≤ 0.30 times) small batch batch dosage from 350kg / batch to 500kg / batch , But still hold
