<P>PROBLEM TO BE SOLVED: To provide a method of conveying a rolled stock and a rolling apparatus, by means of which the rolling time for the rolled stock is shortened. <P>SOLUTION: After a slab is rolled at the first pass, the tail end is positioned at a tail end stopping position and stops. The conveyance of the slab 2 is started at the point of when a control section 7 detects that, during operation of the APC (Automatic Position Control) of a roughing mill 3, difference between the present value of a screw-up position APC of the roughing mill 3 and the target value of the screw-up position APC is not larger than d<SB POS="POST">1</SB>(expecting screw-up APC is completed) and the difference between the present value of the screw-down position APC of the roughing mill 3 and the target value of the screw-down position APC is not larger than d<SB POS="POST">2</SB>(expecting screw-down is completed). When the completion of the APC of the roughing mill 3 is detected, the back table rollers 6 are controlled by the control section 7 and the acceleration control of the slab 2 is performed. Meanwhile, when it is detected that the APC of the roughing mill 3 is incomplete, the back table rollers 6 are controlled by the control section 7, whereby the stop control of the slab 2 is performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
