A method for production of steel comprises the its smelting in steel-smelting unit, tapping of liquid steel in ladle, deoxidation of metal by ferroalloys and out-of-furnace processing with final refining of chemical analysis of steel by ferroalloys and powder wires. In addition, calcium carbide is added in liquid metal during steel smelting in steel-smelting unit before tapping or during tapping, or during deoxidation of metal before introduction of ferroalloys, or during out-of-furnace treatment before final refining of chemical analysis of steel by ferroalloys and powder wires, at that calcium carbide can be used at all production phases of steel, and separately on each of them, and consumptions of calcium is established depending on metal level oxidability.
