Abstract

1501627 Rolling mill control DAVYLOEWY Ltd 2 April 1975 [1 April 1974] 14258/74 Heading B3M [Also in Division G3] A method of operating a tandem strip mill involves keeping constant the interstand tension in a strip S being rolled between a pair of stands, by adjusting the roll gap of either the upstream or downstream roll stand, and keeping the strip gauge constant by varying the roll speed of either the upstream or downstream stand. In one form, the strip gauge is measured at 7 and any error signals are used to control the speed of rolls 1 and 2 (or alternatively rolls 5 and 6). The strip tension is measured by determining the pressure acting on a pivoted roller 8, and any error signal is similarly used to adjust the roll gap of either roll pair. In place of the roller 8 a looper roller may be used, the position of the roller providing an indication of the strip tension.
