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 casting thin metal products by solidifying the molten metal on the cooled lateral surfaces of two parallel horizontal rolls rotating in opposite directions, in which the casting space between the rolls is closed laterally by side dams each comprising an insert penetrating into the space between the rolls. A consumable or deformable material is provided between the rolls and the insert to provide a fluid-tight seal joint between the lateral faces of the inserts and the ends of the opposite rolls. The seal changes shaped by being consumed or deformed to maintain the fluid-tight seal as the rolls expand due to contact with the molten metal.

Device for the continuous casting of thin metal products between two

The invention relates to a method for starting a device for the continuous casting of molten metal, particularly steel, on a cooled roll (1) rotating about its horizontal axis. An adjacent container (4) contains the metal to be cast and has a front wall (5) whose free upper edge (11) is lowered in order to permit the exit of the metal to be cast, and which is swept by the cooled surface of the roll (1). According to the invention, casting is started with a relatively large lead angle (A) and, when casting has started, the container is displaced by pivoting about a horizontal axis, which can be the axis of rotation of the roll, so as to reduce the lead angle in order to arrive at a nominal working position (4') in which the container is held stationary.
