<p><P>PROBLEM TO BE SOLVED: To provide a mill pacing control method in hot rolling capable of automatically and accurately estimating the time of a hot rolled steel sheet passing a certain point on a line from the extraction at a heating furnace to the completion of coiling, and of making the pitch optimum in a short period of time. <P>SOLUTION: In the mill pacing control method in hot rolling whereby the hot rolled steel sheet rolled at a hot rolling plant is extracted from the heating furnace at an optimum extracting pitch, when determining the arrival time of the hot rolled steel sheet at each predetermined point on the line from the heating furnace to a coiler, a designed calculation value of an acceleration/deceleration point of the hot rolled steel sheet in a rough zone is obtained by a computer, and an actual result value is obtained based on the information from a controller performing the control, and the acceleration/deceleration point of the designed calculation value is corrected by comparing the designed calculation value with the actual result value. <P>COPYRIGHT: (C)2004,JPO</p> |
