Abstract (en)
The control by which a tension is generated on the material to be rolled on the entry side and the exit side of the rolling mill 1 and the control of the roll gap of the rolling mill are exerted in an appropriate manner, thereby suppressing the vibration of the rolling mill exit thickness. A transferring speed of the material to be rolled is controlled by: controlling a transferring speed of the material to be rolled that is inserted in the rolling mill 1 for a rolling operation by the rolling mill based on a thickness of the material to be rolled in the rolled state; and controlling either of a rotation of a reel to unwind and supply the material to be rolled with regard to the rolling mill and a rotation of the rolling mill 1.
