CONTINUOUS CASTING MACHINE FOR THIN WALLED BILLET

摘要

PURPOSE:To eliminate the need for charging a dummy bar into a molten metal by providing a holding plate for molten metal having the plane shape coinciding substantially with the cross section of a casting space for a billet and attaching curved holding members which can be engaged with the surfaces of opposed inclining metallic belts to said plate. CONSTITUTION:A holding plate 10 for molten metal of a channel shape coinciding substantially with the cross section limited by opposed metallic belts 1, 1 forming the long side surface of a casting space 3 and side plates 2 on both short side faces and the bottom ends of holding members 11 consisting of plural metallic bars are fixed to both side walls 10a thereof. The extension parts 11a are bent outward and are made to coincide with the opposed slopes of the belts 1. Scrap is put atop the plate 10 and a molten metal is charged through a charging nozzle 7 into a charging part 4. The bottom end of the nozzle 7 is immersed in the charging metal to charge the metal in an oxidation-free state. A billet is drawn downward integrally with the members 11. The need for inserting a dummy bar into the molten metal is thus eliminated and continuous casting is efficiently accomplished.
