[Also in Division B3] The load applied by a rolling mill stand is automatically regulated in dependence on rolled strip thickness and couples applied to each work roll neck are automatically regulated in dependence on rolled strip shape so as to maintain both thickness and shape constant. In Fig. 1, each frame 1 of a double frame stand of a strip rolling mill houses chocks 4 of a pair of back-up rolls 3 which engage work rolls 2 the necks of which are supported in chocks 10. Screw-down is applied at 7 between the frame and the upper back-up chock 4. Signals from an X-ray gauge (not shown) or from a load cell 8, corresponding to rolled strip thickness, automatically control hydraulic jacks 5 which vary the force between back-up chocks 4 to maintain constant strip thickness. Signals from a rolled strip shape detector, which may be a number of tension detecting rollers across the width of the strip, automatically control hydraulic jacks 11 between work roll chocks 4 as well as a second pair of jacks (not shown) spaced from jacks 11 in the direction of the rolling axis. The forces applied by these two sets of jacks are thus varied in opposite senses so that torque is applied to the work rolls to correct any deviation from a constant shape. Replacing each pair of jacks 11 by a single jack acting through the rolling axis is referred to. Replacing or supplementing jacks 11 by jacks acting between the back-up and work chocks, employing single acting jacks, and arranging jacks to have a horizontal component of thrust are referred to.
