Title
(EN) CONTINUOUS FORGING SYSTEM FOR CAST SLAB STRAND
(FR) SYSTEME POUR LE FORGEAGE EN CONTINU DE BARRES COULEES
Abstract
(EN)
According to the present invention, when a continuous forge working is applied to the final solidifying region of a cast slab strand, in order to perform forge working from the front and rear surfaces thereof under a uniform rolling force in spite of wraps and float-ups during drawing movement of the cast slab strand, positioning cylinders for adjusting the position of an anvil are connected to each other at an oil chamber on the side of a rod and an oil chamber on the side of a head through a working oil flow path having a switching valve, and further, working oil flow paths which are connected to the respective oil chambers on the side of the head of the positioning cylinders are connected to each other through a first bypass course.
(FR)
L'invention se rapporte à un système dans lequel, au moment où le travail de forgeage en continu est appliqué à la région de solidification finale d'une barre coulée en vue de réaliser un forgeage à partir des surfaces avant et arrière de la barre sous l'action d'une force de laminage uniforme en dépit des gauchissements et des gondolements pendant le mouvement d'étirage de la barre coulée, les cylindres de positionnement qui servent à régler la position de l'enclume sont reliés entre eux au niveau d'une chambre hydraulique du côté d'une tige et au niveau d'une chambre hydraulique du côté d'une tête, par l'intermédiaire d'un conduit d'écoulement de fluide hydraulique comportant une soupape de commutation, et des conduits d'écoulement de fluide hydraulique reliés aux chambres hydrauliques correspondantes du côté de la tête des cylindres de positionnement sont en outre reliés entre eux par l'intermédiaire d'une première ligne de dérivation.
