通过分析高炉结瘤与高炉恶性管道的形成机理,结合炉料、渣铁、煤气在炉内的运动规律,以及炸瘤时观察到的现象,得出高炉结瘤与恶性管道都是因为软熔带以下的液态渣铁在与煤气流的相对流动时发生矛盾,已熔化的渣铁被煤气重新吹至低温区域凝固而成。提出了预防高炉结瘤应以改善气、液态相对流动条件为主。高炉结瘤后应及时炸除。 By analyzing the formation mechanism of blast furnace nodules and blast furnace ductile pipes, combined with the movement of charge, slag iron and gas in the furnace, and the observed phenomena during blasting, it is concluded that the nodular and malignant ducts of blast furnace are all due to the melting zone The following liquid slag iron and gas flow in the relative flow of contradictions have been molten iron slag was re-blown gas to the low temperature region from the coagulation. Proposed to prevent nodules in blast furnace should be to improve gas and liquid relative flow conditions. Blast nodules should be promptly removed.
