Abstract
A twin-roll type continuous casting machine for fabricating a metal sheet from molten metal supplied from a ladle comprises a pair of spaced rolls, side weirs disposed on each roll in the lateral direction of the roll, a tundish for reserving the molten metal and supplying the molten metal through a feeder, which is provided above the rolls and below the tundish, to form a melt pool on the upper side of the gap between the rolls so as to fabricate the metal sheet through the gap between the rolls, a pressurizing chamber formed between the rolls and the tundish for gas-pressurizing the melt surface of the melt pool. The arrangement allows the ladle to easily supply the molten metal to the tundish and ensures easy maintenance of the tundish.
