FIELD: metallurgy, namely metal continuous casting. SUBSTANCE: at continuous casting metal melt is poured into casting space restricted by walls and leaves it in the form of casting. In order to completely prevent oxygen contact with metal melt and thereby to eliminate secondary oxidation, oxygen having tendency for penetrating through all possible slits between walls and(or) stuck to walls is sucked off by means of suction device. EFFECT: prevention of secondary oxidation of metal. 21 cl, 3 dwg
