Abstract:
1. A containment device for containment of melt between crystallizing rollers of a casting machine, wherein said crystallizing rollers are able to rotate around two substantially horizontal rotation axes, and are placed in positions such as to define between them a zone of minimal distance between the surfaces of said crystallising rollers and so to allow, in the space above said zone of minimal distance, the accumulation of a melt poured from a tundish or other means of distribution, each of the crystallizing rollers comprising one or more shoulder surfaces lying in a plane normal to the rotation axes of the crystallizing rollers, said containment device comprising, on each side of the crystallizing rollers a lateral containment plate able to fit tightly against at least part of each of said shoulder surfaces whereby it contains the melt, pressing means able to move the lateral containment plate so as to bring it close to and hold it tightly against the shoulder surfaces and remove the lateral containment plate from the shoulder surfaces: wherein the lateral containment plate is fixed to the pressing means through an articulated joint, said articulated joint comprises a flexible connecting element able to sustain the lateral containment plate allowing a horizontal pivoting at least around a pivot axis horizontal and substantially normal to rotation axes; wherein the flexible connecting element comprises a flexible tubular sleeve.
