FIELD: metallurgy. SUBSTANCE: method involves reducing mass pouring rate to 
, where A,B are length and width of intermediate ladle, h is depth of branch pipe plunging into metal, t maximum allowable time for replacement of pouring ladle, r is solidity of metal upon pouring of 85-95% of metal. Apparatus has sluice chamber with closure provided with movable plate having fireproof funnel and mechanisms for moving plate in horizontal and vertical planes. Mechanism for moving plate in horizontal plane is formed as stem and mechanism for moving plate in vertical plane is made in the form of guides, which are directed through sluice chamber wall. EFFECT: increased efficiency, simplified method and construction and enhanced reliability in operation. 3 cl, 5 dwg
