Title (EN) CONTROLLED SURFACE MODIFICATION AS AN INTERMEDIATE STEP IN THE SURFACE TEXTURING OF WORK ROLLS
(FR) MODIFICATION COMMANDEE DE LA SURFACE CONSTITUANT UNE ETAPE INTERMEDIAIRE DANS LE TEXTURAGE DES CYLINDRES DE LAMINAGE
Abstract:
(EN) Apparatus and methods of modifying the surfaces of work rolls and the rolls produced thereby which are used in the manufacture of sheet metals and other sheet materials. The working surface of each roll is processed in a series of process steps which include the step of controlled surface modification as an intermediate step. Other process steps can include texturing such as by means of EDT, EBT, laser texturing, media blasting and chrome coating, among others. Controlled surface modification is carried out at least once as an intermediate process step and it can be carried out additionally at other stages such as at the final stage of the roll surface preparation process. The work rolls produced by the method exhibit improved performance and extended life.
(FR) La présente invention concerne un appareil et des procédés de modification des surfaces de cylindres de laminage et des cylindres produits de la sorte qui sont utilisés dans la production de tôles et d'autres matériaux en feuilles. La surface de travail de chaque cylindre est traitée au moyen d'une série d'étapes de traitement qui comprennent, en tant qu'étape intermédiaire, l'étape de modification commandée de la surface. D'autres étapes de traitement peuvent comprendre le texturage tel que le texturage par décharge électrique, le texturage par faisceau d'électrons, le texturage laser, la projection de milieu abrasif et le revêtement de chrome, entre autres. La modification commandée de la surface est effectuée au moins une fois, en tant qu'étape de traitement intermédiaire, et elle peut être effectuée également à d'autres stades tels qu'au stade final du processus de préparation de la surface du cylindre. Les cylindres de laminage produits au moyen du procédé selon l'invention présentent une meilleure efficacité et une durée de vie prolongée.
