摘　　要：采用感应电炉熔炼取代"冲天炉+电炉"双联熔炼工艺。2种工艺成本核算结果显示:采用电炉熔炼后材料成本节约475元/t,铸件单吨标煤消耗下降279.6 kgce/t,车间燃动成本降低521元/t,基本消除了CO2、SO2排放,减少了炉渣的排放,降低了工人的劳动强度,改善了工作环境。此外还介绍了该项改造及试产过程中出现的主要问题,包括冷却塔水蒸气、炉渣结壳、回炉料清理、球铁白口倾向增大等,以及相应的改进措施。The induction furnace melting process was adopted as the substitute for the former cupola ＋ induction furnace duplex melting process.The melting cost accounting of two melting processes showed that as the result of using induction furnace melting,the cost of melting materials was reduced by 475 yuan/t,standard coal consumption of castings reduced by 279.6 kgce/t,fuel and power cost was reduced by 521 yuan/t,the emission of CO2、SO2 was scarcely eliminated,the labor strength was reduced and the working environment was improved.In addition,the main problems occurring during this reformation process and trial-production process was introduced included：treatment of water steam from the cooling tower,slag crusting,cleaning of returned metal charge,chilling tendency increasing of ductile iron,etc.,as well as the relative improving measures to solve above problems were also introduced.
