Abstract
PURPOSE: To perform good control of plate thickness even when the plate width of a plate to be rolled is varied by controlling the rolling roll opening with the correcting target value corrected according to the variation of plate width.
CONSTITUTION: The plate width of plate to be rolled 10 is measured by plate width measuring instrument 22 on the inlet side of rolling mill 18, and after subtracting the value varied by the variation of plate width from the variation of rolled load according to the variation of plate width, the calculated value is entered in automatic plate thickness controlling device 20. The rolling roll opening target value obtained by correcting the rolling roll opening target value outputted from automatic plate thickness controlling device 20 according to the variation of plate width of the plate to be rolled, which is detected plate width measuring instrument 22, is outputted to reducing screw driving device 24 by controlling device 26. Thus, factors of outer disturbance accompanied with the variation of plate width of a plate to be rolled are separated and the precision of automatic plate thickness control will by increased.
