(DE) VERFAHREN UND VORRICHTUNG ZUM HERSTELLEN EINES METALLBANDES DURCH STRANGGIESSEN
(EN) METHOD AND DEVICE FOR PRODUCING A METAL STRIP BY CONTINUOUS CASTING
(FR) PROCÉDÉ ET DISPOSITIF PERMETTANT DE PRODUIRE UNE BANDE MÉTALLIQUE PAR COULÉE CONTINUE
Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Herstellen eines Metallbandes (1) durch Stranggießen, wobei zunächst in einer Gießmaschine (2) eine Bramme (3), vorzugsweise eine Dünnbramme, gegossen wird, die aus einer vertikalen Orientierung (V) in eine horizontale Orientierung (H) umgelenkt wird, wobei in Förderrichtung (F) der Bramme (3) hinter der Gießmaschine (2) die Bramme (3) einer Fräsoperation in einer Fräsmaschine (4) und mindestens einer Walzoperation in mindestens einer Walzstraße (5, 6) unterzogen wird. Zur Qualitätsverbesserung des Bandes schlägt die Erfindung vor, dass die Walz- und Fräsoperationen im direkten Anschluss an das Gießen der Bramme (3) in der Gießmaschine (2) erfolgen, wobei die Walzoperation in mindestens zwei Teilwalzoperationen in mindestens einer ersten Walzstraße (5) und einer zweiten Walzstraße (6) aufgeteilt ist und wobei unmittelbar vor der ersten Walzoperation oder zwischen den beiden Walzoperationen die Fräsoperation in der Fräsmaschine (4) erfolgt. Des Weiteren betrifft die Erfindung eine Vorrichtung zum Herstellen eines Metallbandes (1) durch Stranggießen.
(EN)
The invention relates to a method for producing a metal strip (1) by continuous casting. According to said method, a slab (3), preferably a thin slab, is initially cast in a casting machine (2), said slab being deviated from a vertical direction (V) into a horizontal direction (H), and in the direction of transport (F) of the slab (3) arranged behind the casting machine (2), the slab (3) is subjected to a milling operation in a milling machine (4) and at least one milling operation in at least one rolling train (5, 6). According to the invention, in order to improve the quality of the strip, the rolling and milling operations are carried out immediately after the slab (3) is cast in the casting machine (2). The rolling operation is divided into at least two partial-rolling operations in at least one first rolling train (5) and one second rolling train (6). The milling operation in the milling machine (4) is carried out directly prior to the first rolling operation or between both rolling operations. The invention also relates to a device for producing a metal strip (1) by continuous casting.
(FR)
La présente invention concerne un procédé permettant de produire une bande métallique (1) par coulée continue. Ce procédé consiste d'abord à couler dans une machine de coulée (2) une brame (3), de préférence une brame mince, qui est déplacée d'une orientation verticale (V) pour venir selon une orientation horizontale (H), puis, dans la direction de transport (F) de la brame (3) au-delà de la machine de coulée (2), à soumettre la brame (3) à une opération de fraisage dans une fraiseuse (4) et à au moins une opération de laminage dans au moins un train de laminage (5, 6). Afin d'améliorer la qualité de la bande, les opérations de laminage et de fraisage sont effectuées immédiatement après la coulée de la brame (3) dans la machine de coulée (2). L'opération de laminage est divisée en au moins deux opérations partielles de laminage dans au moins un premier train de laminage (5) et un second train de laminage (6). L'opération de fraisage dans la fraiseuse (4) est effectuée immédiatement avant la première opération de laminage ou entre les deux opérations de laminage. Cette invention concerne également un dispositif permettant de produire une bande métallique (1) par coulée continue.
