Mill pacing control device and mill pacing control method of hot rolling line

摘要

PPROBLEM TO BE SOLVED: To provide a device and a method for controlling the mill pacing of a hot rolling line, by which scheduled extracting timing of a slab, in which the risk that trouble may occur in the rolling state of a steel sheet which is rolled precedingly is taken into consideration, is dynamically optimized and the maximization of throughput and stable operation are attained. PSOLUTION: The rolling state information of the tension variation of the steel sheet, the thickness and shape of the sheet, the amount of shape variation, etc. is collected and the possibility of the occurrence of the trouble is quantified in real time from the collected rolling state information. From the quantified possibility of the occurrence of the trouble in the rolling state, the extracting timing is corrected in real time in accordance with the possibility of the occurrence of the trouble and a signal for starting the extraction is transmitted to a heating furnace on the basis of the corrected extracting timing.
