Abstract: A side wall is provided for closing off the casting space of a plant for the continuous casting of metal strip between two counterrotating rolls which define a nip area and have horizontal axes, of the type including an upper edge, a lower edge, and a face that defines part of a casting space. The wall includes a lower part for preventing cracking in the side wall adjacent to the nip area that includes a recess filled with a refractory. Preferably, the refractory enclosed by the recess is a material having a lower hardness than the refractory forming the balance of the wall, and high thermal insulation properties.

Abstract: The invention relates to a protective coating for a refractory material member of an ingot mold for continuous casting of metals, especially of steel, which consists of a dispersion of particles in a solvent, said particles including essentially boron nitride and at least one of the following metal oxides: zircon, zirconia, alumina and silica, the boron nitride representing between 20 and 50% by weight of said particles.

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.

Abstract: Installation for continuous casting between two rolls (1,2) having parallel axes and defining therebetween and with two fixed lateral walls (3) a casting space for a liquid metal, each lateral wall comprising at least one lateral part (6) placed against the planar end face of an adjacent one of the rolls and constituted by a portion of a disc having an outside diameter equal to that of the adjacent roll, and a part (12) which is central relative to and confronts the casting space and is composed of an insulating refractory material. The disc portion is made from a material having properties of thermal conductivity and mechanical resistance superior to those of the refractory material and is a frustoconical disc portion whose face having the larger radius of curvature is placed against the adjacent roll and the disc portion defines a frustoconical surface which is in contact with the insulating material of the central part.
