为了降低柳钢炼钢冶炼成本,建议转炉炼钢厂、电炉炼钢厂采用焦作王封铁合金厂用矿热法生产的硅铝铁。矿热法冶炼硅铝铁的特点,是利用低品位铝土矿直接冶炼硅铝铁合金。而重熔法生产的硅铝铁合金是将铝块再行熔化到硅铁中去的冶炼法。与重熔法比较,矿热法有以下的好处:(1)矿热法是采用低品位铝土矿为主要
In order to reduce the cost of smelting steelmaking in Liuzhou Iron and Steel Co., Ltd., it is suggested that converter steel mills and electric steelmaking mills should use the silicon-aluminum-iron produced by the pyrocondensation method at Jiaozuo Wangfang Iron Alloy Works. Mineral heat smelting smelting iron is characterized by the use of low-grade bauxite direct smelting silicon aluminum-iron alloy. The remelting production of silicon aluminum ferroalloy aluminum is remelted into the ferrosilicon to the smelting method. Compared with the remelting method, the heat recovery method has the following advantages: (1) The heat recovery method is to use low grade bauxite as the main
