<P>PROBLEM TO BE SOLVED: To provide a conveyance control method for a rolled material in a hot rolling line capable of minimizing the idling time between rolled materials at an inlet side of a finishing rolling mill even though errors on the rolling time may be generated in a rough rolling mill. <P>SOLUTION: When errors at the actual rolling time are generated on material rolling starting and terminating times of respective stands R1 to R3 set at the time of sampling in a heating furnace 1, the pitch can be corrected by changing the conveyance speed of conveyance tables among the stands R1 to R3 so as to make next stand R2 or R3 located at a downstream side start its rolling at an originally set time. <P>COPYRIGHT: (C)2012,JPO&INPIT |
