Abstract

PURPOSE:To improve dimensional accuracy and shape quality of steel plates by disposing a plate thickness meter and a plate width meter at the outlet side of the final stand of a finishing rolling mill and installing a dimension straightening rolling mill and a tension adding device at the downstream side of the above instruments. CONSTITUTION:A plate thickness meter 12, a plate width meter 14, camber meter 16, plate crown meter 18, and shape detector 20 are disposed at the outlet side of the final stand 10A of a hot finishing rolling mill 10. A straightening rolling mill 24 and a tension adding device 26 are installed at the downstream side of those instruments. The plate thickness meter 12 measures a thickness of a strip 11 and the rolling mill 24 is subjected to a feedforward control in correspondence with a deviation between the measured value and the target plate thickness. Then, a plate width, camber, and plate shape are subjected to a feedforward control in the same manner through the rolling mill 24 or the device 26. In this method, dimensional accuracy and shape quality are im proved over the entire length of the strip 11.
