FIELD: process engineering.
SUBSTANCE: proposed mix comprises the following components, in wt % 10-15 of fluorinated material; 5-15 of silicate clump; 8-15 of silicon oxide-based material; 5-10 of carbon containing material; 3-10 sodium bicarbonate; 0.1-1.5 of lignosulphonate powder; 1-3 of carboxymethyl cellulose; cement makes the rest.
EFFECT: reduced fracture formation and nonmetal inclusions of casting surface, lower corrosion of equipment.
