Study on the Asymmetrical Cold Rolling of Strip under Large Width to Thickness Ratio

摘要

On the condition of the width to thickness ratio 625 of rolled strip, the asymmetrical cold strip rolling process about the width center is studied by using computer numerical simulation method and experimental method. The simulated results of the transverse distributions of the rolling pressure. the 2-directional frictions and the front and back.tensions agree with the experimental reuslts well. It is an important discovery that the rolling pressure has three peak values across the strip width on the condition of large width to thickness ratio.
