<p>PURPOSE:To control exactly a camber by determining the respective strain amounts on the working side and driving side of a rolling mill during rolling, determining the camber amt. from the strain amt. and changing the roll gap. CONSTITUTION:When the front end of a steel plate 5 bites to a rolling mill 7, a camber control device 4 reads the signals from a roll gap measuring device 1, a load cell 2 and a thickness gage 3. The control device estimates the camber amt. of the steel plate by calculating said amt. from the read values. The control device emits the command for the roll gap to a draft control device 8 on the working side of the mill 7 or a draft control device 9 on the driving side from the estimated camber amt. of the steel plate to control the target roll gap thereby controlling the camber.</p> |
