Abstract
Installation de laminage de tubes sans soudure. Installation comprenant un laminoir à cylindres obliques à entraînement planétaire dans lequel la tige de mandrin 8 introduite dans l'ébauche de tube 3 peut être poussée, au niveau de sa pointe 9 exclusivement, jusque dans la zone de déformation 4 du laminoir et peut être ensuite immobilisée du côté de l'entrée, l'ébauche de tube 3 étant poussée par le poussoir 6, 7 et le produit obtenu entrant ensuite directement dans le laminoir étireur et réducteur. Application : simplification des installations de laminage en continu des tubes sans soudure.
