description	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. The protective cover having such the construction can prevent the oxidation and temperature reduction of the surface of the molten steel, so that no foreign substance is mixed in the molten steel thereby a thin plate showing no defect can be produced.
