Abstract:
(EN) The present invention relates to: a steel sheet surface treatment device comprising a transport unit for transporting a steel sheet, and a laser line irradiation unit positioned on the transport route of the steel sheet and irradiating a laser line on the surface of the steel sheet in the shape of a line with respect to the width direction of the steel sheet; and a steel sheet surface treatment method comprising the steps of, by using the steel sheet surface treatment device, preparing a steel sheet and consecutively transporting same, and treating the surface of the steel sheet by irradiating, on the surface of the consecutively transported steel sheet, a laser line in the shape of a line with respect to the width direction of the steel sheet.
(FR) La présente invention concerne : un dispositif de traitement de surface de tôle d'acier qui comprend une unité de transport, pour le transport d'une tôle d'acier, et une unité d'exposition à une raie laser disposée sur le trajet de transport de la tôle d'acier et exposant la surface de la tôle d'acier à une raie laser sous la forme d'une raie dans le sens de la largeur de la tôle d'acier; un procédé de traitement de surface de tôle d'acier qui comprend les étapes consistant, à l'aide du dispositif de traitement de surface de tôle d'acier, à préparer une tôle d'acier, à la transporter consécutivement et à traiter la surface de la tôle d'acier par exposition de la surface de la tôle d'acier, transportée consécutivement, à une raie laser sous la forme d'une raie dans le sens de la largeur de la tôle d'acier.
