<P>PROBLEM TO BE SOLVED: To provide a winding control method capable of inexpensively and accurately performing a fixed-position stop control of tail edge. <P>SOLUTION: When the fixed-position stop control of tail edge in a hot-rolled steel band is executed at the winding end in winding and coiling the hot-rolled steel band around a mandrel by a coiler of a hot strip mill, a tail edge position at the width-directional center in a two-dimensional shape of the tail edge of a rough rolled steel band, which is output from a clop shape meter of the hot strip mill, is compared with a crop cut position. When the tail edge position at the width-directional center is closer to the top end of the rough rolled steel band beyond the clop cut position, the tail edge position at the width-directional center, which is detected by an internal laser sensor on the outlet side of a pinch roll of the hot strip mill, is corrected to be located posterior to that position, and the fixed-position stop control of a finish rolled steel band is executed based on the corrected tail edge position. <P>COPYRIGHT: (C)2013,JPO&INPIT |
