湘潭锰矿冶炼富锰渣的副产品——高磷高锰生铁,年产近2万吨,过去一直作为废铁远销外地。为了开展综合利用,该矿试验小组在水口山矿务局机修厂的协助下,以高磷高锰生铁为主,配入适量的铸造生铁及焦炭、石灰石、萤石进行熔炼。根据锰、磷的合理含量加入75#硅铁调整铁水的含硅量,并加4#稀土镁合金孕育处理,用金属模具及铸件的高温开箱,可控制复合磷共晶析出,
Xiangtan manganese ore smelting manganese-rich slag by-product - high-phosphorus high-manganese pig iron, with an annual output of nearly 20,000 tons, in the past has been exported to foreign countries as scrap iron. In order to carry out comprehensive utilization, the mine test team with the assistance of Shuikoushan Mining Bureau mechanical repair plant to high phosphorus high manganese pig iron, with the right amount of cast iron and coke, limestone, fluorite for smelting. According to the reasonable content of manganese and phosphorus, adding 75 # ferrosilicon to adjust the silicon content of hot metal, and adding 4 # rare earth magnesium alloy inoculation, with metal molds and casting high temperature out of the box, can control composite phosphorus eutectic precipitation,
