Abstract
A thickness control apparatus of a reversing rolling mill has an entry thickness gauge that measures the thickness of the material to be rolled, and entry material speed detector that detects the speed of the material to be rolled. Measured thickness measured by the entry thickness gauge is tracked on the basis of the speed of the material to be rolled detected by the entry material speed detector. A mill delivery thickness calculator calculates thickness on the delivery side of the reversing rolling mill on the basis of the thickness on the entry side and the roll gap detected.
