Abstract

The invention involved a rolling stand, a rolling mill and a method for rolling a pre-formed metal strip. Then continually To keep the metal strip free from wavy in the longitudinal direction of the metal strip After the thickness is reduced by various steps. Commonly used According to this method of invention is used. The method for reducing the thickness with the stepped or wavy sections according to the law (chemical formula), the constant where (chemical formula) is the amount of reduction of the thickness in the regions i and hi shows the magnitude of The resulting thickness of the metal strip 200 after it has been rolled in the area of part i.
