电渣精炼铸造铁水生产球墨铸铁

介绍了采用含镁、钙、稀土等元素氧化物的CaF2基渣系，对铸造铁水进行电渣精炼的实验室和半工业性试验的结果。结果表明，电渣精炼过程的脱硫、却气、去夹杂对获得优质铁水，提高铸件质量有明显的效果。精炼铁水的球化效果好并可大量降低球化剂的消耗。因此，新工艺有可能代替传统的铸造铁水溶炼工艺。

Using Electro slag Melting Process of Cast Molten Iron To Produce Ductile Cast Iron

This paper introduces experimental results of the ESM of cast iron in the laboratory and pilot plant based on predecessor's work by molten CaF 2-based slag systems containing MgO , CaO and RexOy. The results show that the desulfurization ,inclusion removal and gas elimination of the ESM have obvious effects on making iron liquid purified and producing high quality casting ,and indicate that the ESM of cast iron may essentially improve the traditional process of cast molten iron melting as a new technique for making high quality ductile cast iron.
