PROBLEM TO BE SOLVED: To surely perform plate thickness control of a tail end part of rolled stock in a tandem rolling mill.SOLUTION: A plate thickness control method for controlling the plate thickness of a tail end of rolled stock W rolled by a plurality of rolling stands 2 provided at a tandem rolling mill 1 includes making detectable the stand pass-through occurrence of the tail end of the rolled stock W in the i-th rolling stand 2, and when detecting the stand pass-through of the tail end in the i-th rolling stand 2, reducing the peripheral velocity of a pressure roll 5 in the (i+1)th rolling stand 2 to suppress variation in outgoing side plate thickness of the (i+2)th rolling stand 2. |
