Study on Tension Distribution Calculation Method for Strip Cold Rolling

Article Preview

Abstract:

In order to improve the calculation accuracy of tension distribution, a new method to calculate tension distribution for strip cold rolling is carried out. First, exit unit tension calculation model is developed by using variational calculus method. Then combined with divided element method, tension distribution and rolls deformation model are established, and the corresponding procedure is developed. Further, contact pressure between rolls and tension distribution of a single-stand reversing cold mill are calculated with the procedure. And it is proved that the results of the calculated data agreed well with the measured value. This verifies that the calculation method is reliable.
