FIELD: metallurgy. SUBSTANCE: air is beneficiated with oxygen and share of oxygen in air does not exceed 0.006 (% И)2 + 40 %, with (%U) - share of lime in mixture. As the result, productivity is increased and explosive capability is decreased. EFFECT: steel production method is used in smelting aggregates, using metal blasting by oxygen and coke dust in mixture with lime in air stream. 1 dwg, 2 tbl
