FIELD: metallurgy. ^ SUBSTANCE: method includes charging of scrap metal, iron-bearing of metal-addition, pouring of liquid cast-iron or carbonaceous intermediate product, lead-in fluxing materials, melting of metal-charging, fining of the melt. The charging of metal-addition is realized by reduced specific surface, equal or bigger 50 m2/t at quantity of 5 - 250 kg/t of steel. To pounded iron-bearing metal-addition is fed the oxygen consumption 2 - 65 m3 to 1 t of metal-addition. ^ EFFECT: reduce of the oxygen consumption and reduce of the duration of melting. ^ 5 cl, 1 tbl, 9 ex |
