The invention relates to ferrous metallurgy, in particular, to methods for casting boiling steel, and can be used to produce large boils from boiling steel. The purpose of the invention is to improve the macrostructure and improve the quality of the ingot surface, increase the yield of yield and the level of mechanical properties of the metal. The method consists in introducing crushed metal additives in the amount of 1-2.5% in proportion to the linear casting speed for 75-80% of the casting time, starting from the moment of filling the mold on 15 -20% of its height, and metal additives contain carbon and silicon in a ratio from 1: 1 to 1:30.
