PURPOSE:To prevent generation of bulging by guiding and supporting metallic belts from the rear side by means of metallic pads from the sprue where a molten steel is charged up to the point where solidification is completed to obviate exerting bending or straightening stress to an unsolidified billet. CONSTITUTION:A pair of metallic belts 2 are positioned to face each other and are circulated. These belts are supported by guide rollers 3, 4, 5, and metallic pads 6 are provided on the rear thereof from the charging port A in a casting space 1 to the point B where the solidification of a molten steel is completed, to guide and support continuously the belts 2. Cooling water is run between the belts 2 and the pads 6. The molten steel is charged from a tundish 7 into the space 1 by an immersion nozzle 8, and the molten steel 9 is thoroughly solidified from the port A to the point B through the belts 2. The belts 2 and the pads 6 exert only the static pressure to the molten steel 9 without exerting bending or straightening stress on the unsolidified billet. A problem such as bulging in the unsolidified billet is thus eliminated. |
