高炉结瘤严重地破坏炉料的顺行和煤气流正常分布,导致产量降低和焦比升高,甚至迫使高炉无法继续生产,只好休风进行处理.近年来3~#4~#(255米~3)高炉均发生结瘤.从1978年以来,3~#高炉每年都要结瘤(见表1),本文对结瘤原因及予防措施进行分析研究. Blast furnace nodules seriously destroy the normal distribution of charge and coal gas flow, resulting in reduced output and coke ratio, and even forced the blast furnace can not continue to produce, had to deal with the wind alone. In recent years 3 ~ # 4 ~ # (255 m ~ 3) All nodules have occurred in the blast furnace, nodules have been formed in the blast furnaces 3 ~ # year after year (Table 1). The reasons for the nodulation and preventive measures are analyzed in this paper.
