Abstract (en)

A method is claimed for the continuous casing of thin metal products between rolls, according to which the molten metal is cast in a casting space (3) defined by the cylindrical walls of two rolls (1,2) with parallel axes. These rolls are counter rotated and internally cooled. Two fixed lateral closing walls (4) are placed against the front end surfaces of the rolls. A lubricant is spread on these front surfaces (5) to lubricate the interfaces between the rolls and the walls and the solidified product is extracted in a direction (F) essentially perpendicular to a plane containing the axes of the rolls. A system (18, 19) is provided to measure one or more parameters representing the rubbing or sealing conditions of the roll-wall interfaces and the quantity of lubricant is regulated as a function of the values of these measured parameters in order to remove the lubricant and thus provoke a temporary more rapid erosion of the closing walls. The device used to put this method into service is also claimed. <IMAGE>

Abstract (fr)

Pour gérer l'usure des parois (4) d'obturation latérales, le dispositif comporte des moyens (8) pour déposer un lubrifiant sur les surfaces frontales (5) des cylindres (1, 2), des moyens (18, 19) de mesure d'un ou plusieurs paramètres représentatifs des conditions de frottement ou d'étanchéité à l'interface cylindre-paroi d'obturation, et des moyens de réglage de la quantité de lubrifiant amené au dit interface en fonction de la valeur de ce ou ces paramètres, tels que des racleurs (13) ou des brosses (14), pour enlever du lubrifiant déposé, et provoquer ainsi temporairement une érosion plus rapide des parois d'obturation. L'invention s'applique en particulier à la coulée continue entre deux cylindres de produits minces en acier. <IMAGE>
