Title (EN) MULTI-FUNCTIONAL ROLLING STAND AND RELATIVE METHOD OF USE
(FR) CAGE DE LAMINAGE MULTIFONCTIONS ET PROCEDE D'UTILISATION ASSOCIE
Abstract:
(EN) Multifunctional rolling stand (10) and relative method of use, suitable for rolling /forging large plates, large blooms, large round pieces and other large-size semi-worked products, for example ingots or similar products. The compression force can reach up to about 6000 tonnes in the case of ingots, depending on the type of product being worked and on the reduction ratio to be obtained. Thanks to these high forces in play, which allow to obtain compressions comprised between 100 and 150 mm, the rolling stand (10) according to the present invention is similar to a forge so that the internal porosities of the product are eliminated.
(FR) La présente invention concerne une cage de laminage multifonctions (10) et un procédé d'utilisation associé, apte au laminage/forgeage de grandes tôles, de grands blooms, de grandes pièces rondes et d'autres produits semi-finis de grande dimension, par exemple des lingots ou produits analogues. La force de compression peut atteindre jusqu'à environ 6000 tonnes dans le cas des lingots, dépendant du type de produit en cours de travail et du taux de réduction à obtenir. Grâce à ces forces élevées en jeu, qui permettent d'obtenir des compressions comprises entre 100 et 150 mm, la cage de laminage (10) selon la présente invention est semblable à une forge de sorte que les porosités internes du produit sont éliminées.
