FIELD: metallurgy.SUBSTANCE: proposed method comprises loading charge composed of the mix of steel and iron chips into alundum crucible, smelting in furnace at 1250-1300°C, holding at said temperature for 3-4 min, unloading from the furnace and tempering in water to produce a ledeburite form inhomogeneity composed of white pig iron. Then, obtained ingot is heated to 680-800°C, forged and tempered to obtain composite structure martensite-white pig iron.EFFECT: simplified process, homogeneous properties.1 tbl, 8 dwg, 1 ex |
