Abstract

A side dam assembly for a continuous casting apparatus for continuously casting thin steel strips between casting rolls. The side dam assembly has a side dam for bearing directly against the rolls of the casting apparatus for preventing leakage of molten metal therebetween. The side dam is attached by a pair of belts to an insulating refractory plate which is carried by a cooled panel. To allow axial motion, one of the belts is not rigidly affixed to either the insulating refractory plate or the side dam. The cooled panel is carried by a thrust plate and is urged toward the rolls by biasing elements which preferably comprise a plurality of pistons urged outwardly from the thrust plate by springs. Preferably, the biasing elements are constructed and arranged so that they are distributed over a zone of shape corresponding to that of the side dam and are capable of exerting on the side dam thrust forces independently of one another.

Dependent claims

Device for continuous casting of thin metal products between rolls, including two cooled counter-rotatory rolls, two side dams and means for supporting and applying by pressure said side dams against ends of said rolls, characterized in that said support means include:

(a) a thrust plate which can be moved in an axial direction (A) of said rolls and which is arranged generally perpendicular to said axial direction;
(b) a panel, which supports one of said side dams and which is carried by said thrust plate and is arranged facing the latter;
(c) at least three thrust members interposed between said thrust plate and said panel, said thrust members being distributed over a zone of shape corresponding to that of said side dam, and being capable of exerting on said side dam thrust forces independently of one another;
(d) a support carriage for carrying said thrust plate and which can be moved in said axial direction, and which includes;
a means for displacing said carriage relative to said rolls for enabling a force to be exerted on said rolls.
