The method of combining automatic gauge control and strip profile control in a tandem rolling mill comprises detecting a signal representative of the actual roll separating force in a first tandem stand and utilizing that signal to maintain a constant roll force in that stand through interstand tension control within predetermined limits and where the tension limit would be exceeded utilizing the signal to simultaneously control the roll gap for gauge control and control the roll bending for strip profile control in the first stand. The interstand tension is controlled either through the speed control of the first stand and/or the gap control of a downstream stand or through a combined tension control loop which initially adjusts tension through an interstand looper and thereafter adjusts the interstand looper to a set point through speed control of the first stand.
A method of combining automatic gauge control and strip profile control in a tandem rolling mill having at least an upstream and downstream four high roll stand with roll bending means comprising:
