重钢三号高炉从1960年投产迄今,发生过三次结瘤.第一次于1967年2月在高渣口方位的炉身上部结成局部瘤,因部位高,采用炸瘤处理.第二次于1972年在炉身中下部和炉腰炉腹结了环形瘤,采取化瘤处理.第三次于1982年2月,在支梁式水箱下部直到炉腰炉腹又结了环形瘤,但较1972年结的深而厚,处理更难. 一、瘤的形成经过我厂原料较差,矿种多,成分复杂,波动很大.据结瘤前统计,入厂矿石含铁量,高的达59.45%,低的仅44.9%,虽经中和,波动仍为含铁高的56.9%,低的49.9%;
The No.3 blast furnace has been in operation for three times so far since it was put into operation in 1960. For the first time, a local tumor was formed in the upper part of the shaft at the high slag mouth in February 1967, Second in 1972, in the lower part of the furnace body and hearth furnace abdominal tumor abdominal tumor, to take the tumor treatment.The third time in February 1982, in the lower part of the beam tank until the stovepipe and bovine ring tumor, But deeper than the knot in 1972 and thicker, more difficult to deal with .Tumor formation through the plant raw materials are poor, more minerals, complex composition, great fluctuations.According to the pre-nodular statistics, iron content into the ore, High up to 59.45%, low of only 44.9%, although neutralized, the volatility is still high iron 56.9%, low 49.9%;
