ABSTRACT:
A method of and apparatus for correcting the rolling load distribution ratio between given stands in a continuous rolling mill involves comparison of rolling load amounts at a pair of adjacent stands with a load distribution ratio set value. When coincidence is not found, the plate thickness on the exit side of an upstream side one of the pair of stands is changed, and at a time when a plate thickness changing point reaches the downstream side stand, the rolling reduction position at the downstream side stand is corrected so as not to change the plate thickness on the exit side of the downstream side stand.
