Abstract

PURPOSE:To easily obtain a composite metallic plate without restriction in material quality by delivering molten metals along the surfaces of a pair of water cooled rolls rotating in the directions opposite from each other from molten metal pools provided on both sides of the rolls to form solidified shells, then rolling the solidified shells. CONSTITUTION:The molten metals A0 and B0 poured into the molten metal pools 3, 4 provided on both outsides of a pair of the water cooled rolls 1, 2 are cooled and solidified by contacting with the rolls 1, 2 to form the solidified shells A1, B1. The shells A1 and B1 are lifted from the pools 3, 4 by the rotation of the rolls 1, 2 and are fed in the direction of the roll gap l while growing. The shells A1, B1 which are still in the high-temp. state upon completion of solidification are press-welded to each other to form an integral composite metallic plate in the roll gap l part. The composite metallic plate is further rolled by the rolls 11 in some cases and is thus made into a product.
