Definitions

  • the rolls wear during use.
  • the work rolls are relatively often grinded so as to re-instate their original form, or new work rolls are used, but the back-up rolls should have a life span of more than 10 times that of the work rolls.
  • the wear of the back-up rolls is such that the back-up rolls have to be grinded more often. This amounts to a considerable cost.

Abstract

La présente invention concerne une cage de laminage pour le laminage d'un matériau allongé, comprenant deux cylindres A et deux cylindres B, les cylindres A et/ou les cylindres B ayant une forme non cylindrique et, pendant le laminage, un cylindre A étant en contact avec un cylindre B sur une longueur des cylindres de 0 à Y. Selon l'invention, le rayon du cylindre B est un facteur constant multiplié par le rayon du cylindre A à toutes les positions X du contact entre le cylindre A et le cylindre B de 0 à Y, plus ou moins une faible différence dans le rayon du cylindre A et du cylindre B à toutes les positions X entre 0 et Y. La présente invention concerne également des cylindres coopérants destinés à être utilisés dans la cage de laminage selon l'invention, et à un cylindre de secours et/ou à un cylindre intermédiaire destinés à être utilisés dans la cage de laminage ou en tant que partie de cylindres coopérants. La présente invention concerne en outre des procédés d'utilisation desdits cylindres dans une cage de laminage.
