Abstract

L'invention concerne un procédé et une installation pour laminer à chaud des feuillards d'acier (S), l'installation présentant une table de laminage à chaud (2) qui comporte plusieurs cages de laminoir (S1 - F7) parcourues successivement dans la direction de transport (F) du feuillard d'acier à laminer à chaud et un tronçon de refroidissement (5) pour refroidir intensivement le feuillard d'acier (S) laminé à chaud sortant de la dernière cage de laminoir (F7) de la table de laminage (2). L'invention permet de produire de manière sûre sur la base d'une telle installation conventionnelle de laminage à chaud des feuillards à chaud ayant une épaisseur finale de plus de 15 mm qui satisfont aussi aux plus hautes exigences pour ce qui est de leur ténacité. Selon l'invention, ce but est atteint du fait que le début du tronçon de refroidissement (5) est transféré avant la fin de la table de laminage (2) vu dans la direction de transport (F) du feuillard d'acier à laminer à chaud et que le tronçon de refroidissement (5) commence à la suite de la dernière cage de laminoir (F5) qui est parcourue avant l'entrée dans le tronçon de refroidissement (5) et dans laquelle un laminage à chaud du feuillard d'acier (S) à laminer à chaud a lieu.
