PREPARATION METHOD OF LAMINATE STEEL SHEET

摘要

PURPOSE: Provided is preparation method of laminated steel sheet in which a certain distance between a roll and a film is maintained in the laminating process so that temperature of the roll is easily managed and, by heating the film, problems such as air insertion and folding of the film due to big temperature difference between the film and the metal sheet are eliminated. CONSTITUTION: The method comprises of the resin film wrapping and revolving around the roll at a certain distance so as to manage the temperature of the roll without the need of an extra cooling roll and the film adhering to the steel or aluminum sheet to make the laminated steel or aluminum sheet.
