前言高炉富氧鼓风是强化冶炼,降低燃料消耗的有效措施。首钢、鞍钢、上钢、本钢及马钢等企业利用炼钢余氧,在高炉冶炼生铁时采用富氧鼓风,取得较好效果。我国现有19座锰铁高炉,其产量占全国铁合金总产量的30%以上,由于各种原因锰铁高炉未能应用富氧鼓风。新余钢铁厂第一炼铁分厂曾于1982年和1983年在容积为255m~3的1~#、2~#锰铁高炉上断续进行富氧鼓风,取得了比冶炼生铁好得多的效果,为我国锰铁高炉改造、采用新
Introduction Blast furnace oxygen-enriched blasting is an effective measure to strengthen smelting and reduce fuel consumption. Enterprises such as Shougang Group, Anshan Iron and Steel Group, Shanghai Steel Group Co., Ltd., Benxi Steel Group Co., Ltd., and Masteel Group Co., Ltd. made use of oxy-fuel for steelmaking and used oxygen-enriched blast air to smelt pig iron in the blast furnace, achieving good results. China’s existing 19 ferromanganese blast furnace, its output accounted for more than 30% of the total output of ferroalloy, due to various reasons ferromanganese blast furnace failed to apply oxygen-enriched blast. Xinyu Iron and Steel Plant, the first ironmaking plant in 1982 and 1983 in the volume of 255m ~ 3 1 ~ #, 2 ~ # ferromanganese blast furnace intermittent oxygen-rich blast furnace, made much better than smelting pig iron The effect of China’s ferromanganese blast furnace renovation, the new
