Zusammenfassung:PURPOSE:To stabilize operations by supplementing stop, addition, and adjusting cycles of slab charging to a present execution cycle after execution of the cycle for alternate rolling by combining a 1st and a 2nd heating furnaces. CONSTITUTION:Proceeding of cycles is checked as rolling proceeds; at the time of rejecting a DHCR stock 8, a matching zone control is performed and the rear end is cut. In accordance with situations, supplement of cycles and change of infurnace instruction are performed. As for all of those operations, an extractive sequence for a 1st heating furnace 1 and a 2nd heating furnace 2 is decided by commands from a vidicon 11. By this method, stable operation is possible.
