一、引言日本高炉解体的实践证明:把实际正在生产着的高炉,保持生产状态的原样而停炉,急速冷却,进行炉内状况调查,这是深刻地最直接了解炉内状况的有效方法。联邦德国曼内斯曼的杜依斯堡一霍金根冶金工厂,计划用N_2冷却一座高炉,计划的要点是:结合对高炉炉内外的实际测试,考查高炉用 N_2冷却后,炉料质量指标与炉料在炉内实际状态和炉料结构与透 I. Introduction The collapse of the Japanese blast furnace has proved that it is an effective and profound way to know the condition of the furnace in a deep and direct way by shutting down the furnace and rapidly cooling the blast furnace that is actually being produced while keeping the state of production. Federal Republic of Germany, Duisburg Huijingen Metallurgical Plant, plans to use N_2 cooling a blast furnace, the plan points are: combined with the actual test inside and outside the blast furnace to test the blast furnace with N_2 cooling, the charge quality indicators and charge The actual state in the furnace and charge structure and through
