Abstract

L'invention concerne un équipement de laminage dont les cylindres de travail de deux groupes de cylindres sont maintenus par des supports mécaniques unitaires. La section d'entraînement et la section de travail du matériau à laminer sont maintenues au niveau de leur côté supérieur par des supports métalliques unitaires, séparés, ainsi qu'au niveau de leur côté inférieur par des supports métalliques similaires. Les deux groupes de cylindres sont placés tout près l'un de l'autre afin d'éviter que le matériau ne forme des courbes et ne se ploie. Grâce à ce procédé, ce laminoir et cet équipement sont faciles à maintenir, et on peut ainsi obtenir un haut rendement de laminage.
