Abstract
The side dam comprises a layer in contact with the molten metal constituted by a refractory material of fibrous structure and composed mainly of alumina and silica, and a second layer which is provided behind the first layer and composed of compact refractory material. The fibrous layer ensures the thermal insulation and the compact layer acts as a safety plate. The invention permits the construction of side dams which are capable of both durably ensuring the sealing of the molten metal and preventing untimely solidifications of the metal upon contact with these side dams. The invention is preferably applied to the continuous casting between rolls of hard metals having a high melting temperature, such as iron and its alloys.
