摘要:Abstract: To use scrap instead of pure iron in intermediate frequency induction furnace smelting ultra low carbon ferrite stainless steel, a variety of scraps were used in ultra low carbon ferrite stainless steel production practice. The results show that, the content of carbon can be reduced to 0.025% by oxygen blowing process, it is necessary condition that silicon content reduced to around 0.005% in oxygen blowing smelting ultra low carbon steel, and it can effectively solve the production pro- blems such as high slag melting point and molten slag crusting by ferrosilicon deoxidization after oxygen blowing, cooperating with the calcium silicon and clay piece of slag modification, making slag basicity 0.8 to 1.2, and lowering initial FeO and Cr2O3 content.
