FIELD: technological processes, casting.
SUBSTANCE: invention is related to the field of ferrous metallurgy, in particular to continuous pouring of steel. Slag-forming mixture contains (wt %): carbon-containing material (4 - 8), fluorine-containing material (15 - 20), silicate mass (3 - 10), sodium bicarbonate - baking soda (5 - 15), material on the basis of silicon oxides (13 - 18) and cement (the rest). Using sodium bicarbonate in mixture together with material on the basis of silicon oxide makes it possible to improve quality of continuous cast billet surface due to increased assimilating ability of mixture in respect to oxides that float from metal at initial moment of pouring.
EFFECT: improved operation of mixture at continuous pouring of steel,also during technological operations, such as replacement of intermediate bucket or submersible glass.
