Beschreibung
Zusammenfassung:FIELD: metallurgy, namely slag forming mixtures. SUBSTANCE: slag forming mixture for casting steel includes silicate lumps, fluorspar, nepheline, dump slag of ferroalloy production and rice husk with next relation of components (mass%): silicate lumps -(5-20); fluorspar -(12-30); rice husk (0.5-5); nepheline (10-20); dumping slag of ferroalloy production - the balance. Mixture may include carbon containing material in quantity equal to 0.01-12 mass %. EFFECT: enhanced quality of ingot due to elimination of its surface defects, reduced heat conductivity of slag mixture, high heat insulation of mixture. 2 cl, 2 tbl
