Measurement and Calculation of Transversal Internal Stress Distribution in the Off-line Cold Rolled Strip

The transversal internal stress distribution in the off-line cold rolled strips sampled for a 1700mm cold tandem mill was measured by the modified hole-drilling technique. Based on the conclusions drawn from the experiment, an available method for calculation of the internal stress distribution was established, which can give fairly identical solution with the test. This numerical method for transversal internal stress calculation can be used in the on-line automatic flatness control.
