ABSTRACT:
To operate a rolling mill to roll metal strip with a satisfactory degree of flatness, signals from tension detecting means located downstream of the mill rolls are used continuously to determine the best symmetrical parabola which fits the shape of the strip and a parameter of the parabola is used to bring about an adjustment of the bending of the mill rolls in such a sense as to change the parameter substantially to zero. Signals from the detecting means may be used in addition to control the steer of the mill and adjust the temperature of the roll assemblies along their length.
