METHOD FOR CASTING METAL AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2005 - IPC

Abstract RU 2250809 C2

FIELD: metallurgy.

SUBSTANCE: method comprises steps of filling vessel with metal together with slag; immersing refractory member into melt metal; emptying vessel through casting opening. Refractory member embraces body of stopper and it has specific dimensions in plan view. Refractory member is arranged with possibility of free vertical motion relative to stopper. At process of emptying vessel, refractory member vertically moves over casting opening. When casting process is terminated, refractory member self-descends until contact with bottom of vessel. Stopper is descended until contact with casting opening. Size of refractory member exceeds by several times diameter of casting opening.

EFFECT: prevention of funnel formation at end of casting and elimination of slag immersion in metal.
