Title (EN) TWO STAND TANDEM FOR ROLLING LINE
(FR) DOUBLE CAGE EN TANDEM POUR LIGNE DE LAMINAGE
Abstract:
(EN) Tandem with two reversible four-high rolling stands (14a, 14b) for the cold rolling of thin strip up to 0.18 mm, advantageously from 0.18 to 1.2 mm, comprising at least a first (12a) and a second (12b) drawing reel, means to heat the rolls and the lubricating oils, a control and command unit, a first, usual lubrication system (17), the working rolls (15) being associated with replacement rolls (115), the stands (14a, 14b) including a first working condition with the working rolls (15) and at least a second working condition with the replacement rolls (115), wherein below the stands (14a, 14b) there is a first (20a) and a second (20b) collection tank to collect the lubrication fluid, there also being a second finishing lubrication system (18) which can be activated in alternation with the first system (17), the first (20a) and second (20b) collection tank being equipped with switching means (21) whose command means (22) are controlled by the command and control unit (31), each of the switching means (21) being equipped with at least two ways (30a, 30b) which can be activated in alternation, a first (28a) and a second (28b) containing reservoir tank cooperating respectively with a first (24a) and a second (24b) circulation pump, each of the pumps (24a, 24b) feeding the respective first (17) and second (18) lubrication system.
(FR) L'invention a trait à deux cages en tandem (14a, 14b) de laminoir réversible à quatre cylindres aux fins du laminage à froid de bandes minces d'une épaisseur pouvant atteindre 0,18 mm et, pour un meilleur résultat, d'une épaisseur comprise entre 0,18 et 1,2 mm, comprenant au moins un premier (12a) et un second (12b) enrouleur d'étirage, un dispositif destiné à chauffer les cylindres et les huiles lubrifiantes ainsi qu'une unité de contrôle et de commande. L'appareillage comporte également, d'une part, un premier système ordinaire de lubrification (17), les cylindres de travail (15) étant associés à des cylindres de rechange (115) et les cages (14a, 14b) ayant un premier état de fonctionnement avec les cylindres de travail (15) et au moins un second état de fonctionnement avec les cylindres de rechange (115) et, d'autre part, un second système de lubrification de finissage (18) pouvant être actionné en alternance avec le premier. Sous les cages (14a, 14b) se trouvent un premier (20a) et un second (20b) réservoir de collecte destinés à recueillir le fluide lubrifiant. Ces deux réservoirs de collecte (20a, 20b) sont équipés d'organes de commutation (21) dont les systèmes de commande (22) sont régis par l'unité de contrôle et de commande (31), chacun de ces organes de commutation (21) étant pourvu d'au moins deux passages (30a, 30b) pouvant entrer en fonctionnement en alternance. L'appareillage comprend aussi un premier (28a) et un second (28b) réservoir conteneur coopérant, respectivement, avec une première (24a) et une seconde (24b) pompe de circulation, chaque pompe alimentant, respectivement, le premier (17) et le second (18) système de lubrification.
