For such a profile,
It is necessary to guarantee the plate thickness over the entire length and width of the hot coil. However, the plate thickness control in the conventional hot rolling finishing process is performed by superposing the total length thickness measurement by the one-point measuring thickness meter at the plate center and the plate profile measurement in the hot coil 1 to 3 times by the width direction scanning type thickness meter. Came.

Reference numeral 8 in the drawing denotes a strip width detector normally installed on the exit side of the finishing rolling mill. In the case of this example, since the plate width value W o is directly measured by the plate width detector 8, the plate width calculation by the arithmetic unit 6 as in the first embodiment is unnecessary. However, if the installation position of the plate width detector 8 and the installation position of the U-shaped moving frame are not close to each other, distance correction is necessary.
