To Melt 40 Cr Steel in Intermediate Frequency Induction Furnace with Bearing Steel’s Scrap
To preheat the steel’s scrap trough study on chemical composition control and smelting technique of 40Cr steel smelted in intermediate frequency induction furnace and using bearing steel’s scrap, it is proved that the combination of lowering carbon, degasification, reverted iron is useful to use waste steel’s scrap.
