Summary:PROBLEM TO BE SOLVED: To effectively suppress opposed thickness deviation caused when rolling with a mandrel mill. SOLUTION: In the control method of the roll gap when rolling with the mandrel mill, the number of roll passes and the abrasion loss of the rolling roll are preliminarily measured. When starting the rolling, the roll gap is corrected in accordance with the abrasion loss of the rolling rolls predicted on the basis of the relationship of both measured from the number of the roll passes. Then, the proper correction of the roll gap is performed in accordance with the actual abrasion loss of the rolling roll.
