利用废钢、废铁(灰铸铁、球铁)、钢铁切屑、回炉铁、新生铁为原料，以感应电炉来熔炼灰铸铁(球铁)，其铁液与冲天炉熔炼铁液相比过热温度高，熔化保温时间长，极易引起脱碳。同样化学成分，同样铸型浇成的铸件，比冲天炉熔炼的强度、硬度高；激冷白口倾向大；石墨长度较短，且?
The use of scrap steel, iron scrap (gray iron, ductile iron), steel chips, iron, new iron as raw material, induction furnace to smelt gray iron (ductile iron), the molten iron and cupola melting hot metal temperature is high , Melting and holding a long time, can easily cause decarburization. The same chemical composition, cast the same castings than the intensity of cupola melting, high hardness; chilled white mouth tends to be large; graphite length is shorter, and?
