鞍钢在鲅鱼圈建设2座有效容积为4 038m3高炉,年生产能力650万t,高炉工序特点如下。1)高炉炉体结构。在总结国内外高炉长寿经验的基础上,结合鞍钢的原燃料条件和高炉富氧大喷煤后的内型发展趋势,为改善高炉透气性和充分利用煤气化学能,适当加大了高炉下部容积和降低炉身高度,适当降低高炉的高径比(2.12)、炉腹角79°58′44″,提高炉缸高度、增加死铁层深度(3.0m)。在容
Anshan Iron and construction in the Bayuquan 2 effective volume of 4 038m3 blast furnace, annual production capacity of 6.5 million t, blast furnace process are as follows. 1) blast furnace body structure. On the basis of summarizing the experience of longevity at home and abroad, combined with the raw material conditions of Ansteel and the internal development trend after blast furnace oxygen-rich and big PCI, in order to improve the gas permeability of the blast furnace and make full use of the chemical energy of the gas, the lower part of the blast furnace And reduce the height of the furnace body, properly reduce the blast furnace height to diameter ratio (2.12), the furnace angle of 79 ° 58’44 ", raise the hearth height, increase the depth of the dead iron layer (3.0m)
