Abstract

LE PROCEDE CONSISTE A FAIRE PASSER L'EBAUCHE EN CONTINU A TRAVERS UN LAMINOIR COMPRENANT UNE PLURALITE DE JEUX DE CYLINDRES 1, 2, 3 RAINURES REALISANT DES PASSAGES SENSIBLEMENT CIRCULAIRES ET A SUPPORTER L'INTERIEUR DE L'EBAUCHE TUBULAIRE AVEC UN MANDRIN 11. DANS CE PROCEDE ON MAINTIENT L'EXTREMITE DU MANDRIN AVEC UN MOYEN DE POUSSEE 15 ET COMMENCE LE LAMINAGE EN POUSSANT LE MANDRIN 11 DANS L'EBAUCHE TUBULAIRE, ARRETE LA POUSSEE SUR LE MANDRIN ENTRE LE MOMENT OU L'EXTREMITE AVANT DE LA PIECE TRAVAILLEE A PASSE LA DERNIERE LIGNE DES CENTRES DES CYLINDRES DANS LE PREMIER DEMI-GROUPE DES JEUX DE CYLINDRES ET LE MOMENT OU L'EXTREMITE AVANT DE LA PIECE DE TRAVAIL SE TROUVE EN AVANT DE LA LIGNE DES CENTRES DES CYLINDRES DU DERNIER JEU DE CYLINDRES ET ON POURSUIT LE LAMINAGE DE LA PIECE EN MAINTENANT L'EXTREMITE DE QUEUE DU MANDRIN. LE PROCEDE EST UTILISE POUR LE LAMINAGE SANS SOUDURE D'UN TUBE EN CONTINU.
