<p>THE INVENTION RELATES TO A POURING NOZZLE 30 COMPRISING AT ITS UPSTREAM END 32 A GENERALLY RECTANGULAR SHAPED PLATE 34 WITH A TOP SURFACE 16 AND A BOTTOM SURFACE. THE NOZZLE 30 ALSO COMPRISES A TUBE 38 THE AXIS 40 OF WHICH IS SUBSTANTIALLY ORTHOGONAL TO THE TOP SURFACE I 6 OF THE PLATE 34. THE TUBE 38 EXTENDS FROM THE BOTTOM SURFACE OF THE PLATE 34 TO THE DOWNSTREAM END 36 OF THE NOZZLE. THE NOZZLE COMPRISES A POURING CHANNEL CONSISTING OF THE INLET ORIFICE I 8 FORMED THROUGH THE SURFACE ?1 6 OF THE PLATE 34, A BORE IN THE PLATE 34, A BORE 50 IN THE TUBE 38; THE DOWNSTREAM END 36 OF THE TUBE IS CLOSED AND THE POURING CHANNEL EMERGES CLOSE TO THE DOWNSTREAM END 36 THROUGH OUTLETS 46, 46? FORMED IN THE LATERAL WALLS OF THE TUBE 38. THE ORIFICE OF THE PLATE 34, THE BORES OF THE PLATE AND OF THE TUBE AND THE OUTLETS BEING IN FLUID CONNECTION. THE OUTLETS 46, 46? ARE DISPOSED SYMMETRICALLY ON EITHER SIDE OF THE AXIS 40 OF THE TUBE 38. THE CENTRES OF THE OUTLETS 46, 46? ON EITHER SIDE OF THE AXIS 40 DEFINE AN AXIS 48 OF THE OUTLETS SUBSTANTIALLY ORTHOGONAL TO THE AXIS 40 OF THE TUBE 38. THE AXIS OF THE OUTLETS IS SUBSTANTIALLY PARALLEL TO A PAIR OF SIDES OF THE PLATE 34. THE ORIFICE 18 IS OBLONG AND HAS A MAJOR AXIS 42 AND A MINOR AXIS 44. THE MINOR AXIS 44 OF THE ORIFICE 18 IS PARALLEL TO THE AXIS 48 OF THE OUTLETS. ACCORDING TO ANOTHER OF ITS OBJECTS, THE PRESENT INVENTION ALSO RELATES TO AN ASSEMBLY OF SUCH A NOZZLE WITH AN INNER NOZZLE. THIS NOZZLE AS WELL AS ITS ASSEMBLY WITH AN INNER NOZZLE ARE USED FOR THE CONTINUOUS CASTING OF STEEL FROM A TUNDISH TOWARDS A CONTINUOUS CASTING MOULD.</p> |
