HEATING-FURNACE-EXTRACTION ORDER GENERATION DEVICE HEATING-FURNACE-EXTRACTION ORDER GENERATION METHOD AND STEEL PLATE PRODUCTION METHOD

摘要

The pattern creating unit 103 creates a plurality of process patterns in which each step of the passing process and the occupation time of the equipment used in the process are combined for each rolled material, A mode is created by combining the process patterns selected one by one for each step of the passing process and the mode of the rolled material in which the total rolling time is shortest based on constraint conditions on the product quality and equipment of the rolled material A combination is selected, and on the basis of the combination of the modes of the selected rolled material, a heating furnace extraction sequence and a rolling schedule are made. As a result, both the improvement of the rolling efficiency of the steel sheet and the satisfaction of the product quality condition can be achieved, and the manufacturing efficiency of the steel sheet can be improved.
