The present invention provides a production scheduling method and system for improving product quality and slab extraction efficiency. By obtaining hot rolling production process data and spatial location information of slabs in slab warehouses, the invention can provide a production scheduling method and system based on user needs and hot rolling unit equipment conditions. , determine the range of slab specifications for hot rolling production, establish a pool of candidate slabs for the hot rolling production operation plan, and set the sum of the rolled slab quality and slab extraction efficiency as the objective function, according to the hot rolling production process requirements , calculate the specification change cost between slabs in the candidate slab pool of the hot rolling production operation plan, and then obtain the hot rolling production operation plan based on the objective function and the specification change cost between the slabs, and output the hot rolling production operation plan. Rolling production operation plan, this method is used to reduce production costs, improve product quality and slab extraction efficiency, and ensure the continuity of hot rolling production.
Description
Technical field: [0001] The invention relates to the technical field of metal material processing information, in particular to a production scheduling method and system for improving product quality and slab extraction efficiency. Background technique: [0002] The hot rolling production process mainly goes through four stages: heating furnace, rough rolling, finishing rolling, and crimping. The raw materials used for hot rolling are slabs produced through steelmaking-continuous casting, and the slabs are stacked in stacks in the slab warehouse, such as figure 1 shown. The slabs in the raw material warehouse that are ready to enter the hot rolling rolling line are moved to the furnace roller table by the crane and transported to the heating furnace according to the rolling sequence by the crane and the crane, and heated to the required temperature. After the furnace temperature is released, it is then transported to the rough rolling unit for rolling through the furnace r...
