FIELD: metallurgy, in particular, oxygen-converter steel production. SUBSTANCE: method involves charging into oxygen converter used car casings and scrap in the ratio of (0.009-0.020):1, respectively; introducing slag-forming and carbonaceous materials in the ratio of 1:(0.10-0.35), respectively; supplying oxygen at the rate making 0.25-0.45 of nominal rate for time of about 35% of total heating time; increasing oxygen flow rate to value making 0.6- 0.8 of nominal value, said total scrap heating-through time making 30-65% of total melt blowing time; pouring liquid iron into converter and providing oxygen blowing of melt. EFFECT: reduced consumption of solid carbonaceous heat- carriers and cast iron and increased resistance of liner.
