Rolling Strips Varying Thickness with Elimination of Widening

Abstract:

Widening is always accompanied with longitudinal rolling of strip varying thickness which is used for parabolic leaf springs production. The amount of this phenomenon at strip ends is highest which should be eliminated from end product. In this article a method for gradual elimination of widening during rolling passes is proposed. Idle rollers are used for elimination of rolled strip widening caused by rolling. A method is presented to determine tensile stress in the case of rolled strip drawing by idle rollers. Variation of ratio depending on reduction in width is studied.
