Zusammenfassung:FIELD: ferrous metallurgy, namely compositions of slag forming mixtures used for protecting cast steel in mold at continuous casting of ingots with slab type cross section. SUBSTANCE: slag forming mixture contains mica, fluospar, Portland cement, carbon-containing matter and in addition it includes cryolite, dotolite concentrate, calcium-silicon and coke dust as carbon- containing matter at next relation of ingredients (mass%): mica, 10 -30; cryolite, 2 -20; fluospar, 10 -25; dotolite concentrate, 8 - 12; calcium- silicon, 3 -6; coke dust, 8 - 12; Portland cement, the balance. It is possible to use slag Portland cement as Portland cement and phlogopite as mica. EFFECT: enhanced quality of surface of continuously cast slabs, lowered cost of slag forming mixture. 3 cl, 1 tbl, 5 ex
