Abstract (en)
1.Device for closing externally a vessel (1) containing molten metal, particularly a ladle for casting steel from a converter or an electric furnace in a continuous-casting equipment, comprising a fixed plate (2) having at least one opening (3) and being integral with the vessel bottom, a movable plate (4) provided with at least one opening (5), means so arranged as to press firmly the movable plate (4) against that side of the fixed plate (2) facing outwards of the vessel and to slide the side of the movable plate (4) relative to that side of the fixed plate (2) it does contact, to bring the opening (5) in the movable plate (4) facing the opening in the fixed plate, an inner or top nozzle (8) secured to that fixed plate side facing inwards of the vessel and surrounding the opening (3) provided in said plate to direct the molten metal to said opening and a collecting nozzle (10) secured to that side of the movable plate (4) removed from the fixed plate and surrounding the opening (5) in said movable plate to collect the molten metal flowing through the openings (3, 5) in the fixed and movable plates facing partly or completely one another, said device being characterized in that the inner duct (15) of the collecting nozzle (10) has two adjacent parts (16, 17), the first part (16) which extends from that end of the duct (15) nearest the movable plate (4), having a smaller cross-section than the opening (5) provided in the movable plate (4), the second part (17) of said inner duct (15) having a larger cross-section than the cross-section of the first part (16) of said duct.
