Title
(EN) APPARATUS AND METHOD FOR IMPROVING HOT STRIP MILL PROCESSING
(FR) PROCEDE ET APPAREIL POUR AMELIORER LE LAMINAGE DE FEUILLARDS A CHAUD
Abstract
(EN)
A system for processing steel strips (12) in a hot strip mill (F1, F2, etc) includes an apparatus and method for removing the oxide layer in the finishing mill process such that the final thickness of the oxide layer is much less than previously possible. In order to reduce the thickness of the oxide layer, the invention provides for the removal of the oxide scales from the surface of the steel strips (12) at a distance in front of the working rolls (25a, 25b) of the finishing mill (F1) that minimizes the time the strip (12) is exposed to ambient conditions after it is descaled and before it is received between the pair of working rolls (25a, 25b). By minimizing this exposure time, the thickness of the oxide layers in the finished strips (12) is substantially reduced.
(FR)
Un système de traitement de feuillards d'acier (12) dans un laminoir (F1, F2, etc.) de feuillards à chaud comprend un appareil et un procédé d'élimination de la couche d'oxyde pendant le passage dans le laminoir finisseur, de façon à obtenir une couche d'oxyde d'épaisseur beaucoup plus réduite qu'auparavant. Afin de réduire l'épaisseur de la couche d'oxyde, les battitures d'oxyde de fer sont enlevées de la surface des feuillards d'acier (12) à une certaine distance des cylindres de travail (25a, 25b) du laminoir finisseur (F1) qui réduit au minimum la durée d'exposition du feuillard (12) aux conditions ambiantes une fois que les battitures ont été enlevées et avant que le feuillard ne pénètre entre les deux cylindres de travail (25a, 25b). En réduisant au minimum la durée d'exposition, on réduit considérablement l'épaisseur des couches d'oxyde sur les feuillards finis (12).
