Abstract: Method and apparatus for sealing molten metal for use in twin-roll type continuous casting apparatus for preventing molten metal from entry into a clearance between a pair of mold rolls and side weirs disposed at opposite ends of the pair of mold rolls to define a molten metal reservoir above the gap between the mold rolls. a sealing medium is supplied at the inner side of the side weirs in the vicinity of the border between the molten metal and each of the mold rolls. Entry of molten metal into the clearance is prevented without the necessity of pressing the side weirs against the roll ends.

Abstract: The present invention provides a protective cover for a surface of molten steel used in a continuous casting apparatus provided with a pair of movable mold walls arranged in parallel to each other and a melt receiver formed between said movable mold walls, for example a twin-roll type casting apparatus, said protective cover comprising a central heat insulator capable of bringing into contact with a central portion of a surface of the molten steel other than portions close to portions where the surface of the molten steel is brought into contact with the respective movable mold walls and side heat insulators mounted on said central heat insulator, covering spaces above said portions close to the portions where the surface of the molten steel is brought into contact with the respective movable mold walls and being brought into slidable contact with the surfaces of the respective movable mold walls at pointed end portions thereof.
