ABSTRACT:
A wide thin metal sheet having a smooth surface may be manufactured directly from molten metal. A lower end of a nozzle installed vertically at the bottom of a molten metal vessel is held in contact with an inclined plate made of a refractory material, molten metal is discharged in a fan-shape from a notch formed in the peripheral wall of the nozzle end, the discharged molten metal being rendered into a constant shape laminar flow having a uniform flow rate distribution on the inclined surface as it flows down the inclined plate. The constant shape laminar flow is supplied to a molten metal pool between a pair of rollers of internally water-cooled type without any disturbance on the surface and in the inside. The metal solidified in the neighborhood of a portion of the gap between the two rollers is discharged from an open-at-the-bottom space defined between the two rollers.
