日本水岛铁合金有限公司的一座398m~3高炉于1986年5～9月进行矿焦完全混装入炉试验冶炼高碳锰铁合金,取得焦比降低101kg/t铁,锰收得率提高达到93.5%的显著成果。日本高炉操作稳定与低燃料比(近几年以低成本为主)的效果,主要在于改善炉料性质与炉料分布的控制,特别是最近十分关注对炉壁热负荷与软熔带高度的控制。为了扩大高炉界限操作范围,防止炉况不安定现象,考虑矿石与焦炭完全混合装料,以期得
Japan Mizushima Ferroalloy Co., Ltd. a 398m ~ 3 blast furnace from May to September 1986 carried out fully mixed into the furnace coke furnace smelting high-carbon ferromanganese alloy, coke ratio was reduced by 101kg / t iron, manganese yield increased to 93.5 % Of the significant results. The effect of the stable operation of the blast furnace in Japan and the low fuel ratio (mainly low cost in recent years) is mainly to improve the control of the nature of the charge and the charge distribution. In particular, the heat load on the furnace wall and the control of the height of the fusible link are very much concerned recently. In order to expand the operating range of blast furnace boundaries, to prevent instability furnace phenomenon, consider the complete mixing of ore and coke charging, in order to obtain
