A cassette for a device for continuously casting liquid metal between two parallel rolls, the cassette includes a metal case which has a lateral wall and is open on a side of the case, and plate of refractory material which may be preheated before casting the liquid metal. The refractory plate is preshaped in such a manner so to define a free space between the periphery of the plate and the lateral wall of the case. The cassette is provided with an arrangement for fixing and gripping the plate and exerting an elastically yieldable opposing action allowing free expansion of the plate within the case.

Cassette for forming an end closing side of a device for continuously

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. The invention is applicable to the continuous casting of thin metallic products, in particular of steel.

Installation for continuous casting between rolls

A device for the continuous casting of thin metal strips includes two parallel spaced rotatable rolls, side walls located at the ends of the rolls and defining with the rolls a casting space for liquid metal, a flat cover disposed above the liquid metal and in the immediate vicinity of the meniscus of the liquid metal so as to form a thermal screen which is so dimensioned as to cover the whole of the surface of the liquid metal. The cover is provided with a refractory lining on the side of the cover facing toward the liquid metal and bearing against the two rolls. This cover forms a thermal screen or shield preventing any surface solidification of the bath of liquid metal from starting. Advantageously, an inert gas may be injected between the meniscus and the cover through the latter.

Device for the continuous casting of thin metal strips between two rolls

A closing wall for the lateral end of a casting space of an installation for continuously casting between moving walls which comprises two confronting cooled moving walls (1,2). The closing wall comprises a front part (65) defining a front surface (63) facing toward the casting space and at least one lateral part (66) defining a lateral surface (64) in the extension of the surface of one of the two moving walls and connected to said front surface. The invention is also applicable to the continuous casting of thin metal products between rolls.
