CA 2465290

The invention relates to a damper construction (2) of a furnace coiler (1) which can especially be used in Steckel mills (1). A hot rolled strip is respectively coiled onto, and uncoiled off, a drum inside the furnace in a reversing manner, by means of a back and forth transport movement, and is optionally heated. Guiding flaps (6, 6') are mounted on the displaceable damper (2) of the furnace coiler, for inserting and guiding the rolled strip. In order to improve maintenance work, the dampers (2) and the furnace coiler (1) are embodied as separate components. The dampers (2) are arranged on an element (4') pertaining to a displaceable roller rack (4), said element being located beneath the furnace coiler (1). Each damper (2) is divided into at least two elements (2', 2") which can be hinged together, the two hinged elements being connected by means of a hinge bearing (7) in a pivoting manner.

La présente invention concerne un structure de registre (2) d'un four de bobinage (1) pouvant être utilisé notamment dans des laminoirs de Steckel. A l'intérieur dudit four, un feuillard laminé à chaud est respectivement enroulé et déroulé de façon réversible sur un rouleau en effectuant un mouvement de va-et-vient, et éventuellement chauffé. Sur le registre (2) en mouvement du four de bobinage sont montés des volets de guidage (6, 6') destinés à charger et à guider le feuillard. Afin d'apporter des améliorations à l'entretien, les registres (2) et le four de bobinage (1) sont des corps séparés. Les registres (2) sont disposés sur une pièce (4') d'un longeron de train de rouleaux mobile (4), située en-dessous du four de bobinage (1). Chaque registre (2) est composé d'au moins deux éléments (2', 2") rabattables l'un par rapport à l'autre et les deux éléments rabattables sont reliés par un palier articulé (7) de façon à pouvoir pivoter.
