The invention discloses a rolling energy-saving method based on optimal matching of slab and contract, comprising: reading slab and contract data from a manufacturing execution system and performing grouping processing; a local search algorithm based on variable neighborhood and backtracking strategy, Obtain a set of contract matching candidate lists for slabs; predict slab rolling energy consumption based on rolling schedule setting calculation and BP neural network calculation; Contract matching scheme of minimum rolling energy consumption; send the minimum rolling energy consumption contract matching scheme of slab and corresponding rolling procedures to the manufacturing execution system, and organize rolling production according to them. The method provided by the invention is suitable for the optimization of production management of medium and heavy plate iron and steel enterprises, and organizes production based on the slab contract matching relationship determined by the method of the invention, which can reduce the energy consumption of the slab rolling process and improve the yield of steel product processing. , while ensuring the automatic cutting efficiency of steel plates.
Description
technical field [0001] The invention relates to the energy-saving optimization of the rolling process of medium and heavy plates, belongs to the field of production management optimization of iron and steel enterprises, and in particular relates to an energy-saving method for rolling based on optimal matching of slabs and contracts. Background technique [0002] With the technological upgrading of the iron and steel industry, the energy-saving space for equipment transformation in iron and steel enterprises is getting smaller and smaller. The lean production management and production process control based on computer control to realize energy-saving management has gradually become an important research direction. Steel rolling is one of the high-energy-consuming processes in steel production. Typical results of energy-saving research on steel-rolling link management include, for example, the optimal design of rolling procedures with minimum energy consumption based on optimiz...
