Abstract

The invention relates to an on-line multi-mode time optimization scheduling method for steelmaking and continuous casting production, which comprises the steps: 1, setting process parameters; 2, setting algorithm parameters of a model; 3, receiving actual production, and performing difference calculation with the set parameters; 4, giving crude scheduling advice according to disturbance type, deviation type and deviation value; 5, performing crude scheduling; 6, acquiring charging plan information, equipment information and result information of the crude scheduling; 7, establishing a basic scheduling model and an on-line multi-mode scheduling module; 8, matching a time optimization scheduling mode, performing on-line time optimization, and giving a new scheduling plan; and 9, performing field time scheduling according to a calculation result of the optimization model. The method has the advantages that in the time optimization scheduling process, the method fully considers process constraints, equipment constraints and various modes of decision-making requirements of scheduling personnel, reduces the times of manual plan adjustment, shortens on-line scheduling time, and reduces redundancy waiting time of molten steel.

Description

technical field [0001] The invention belongs to the field of information technology, relates to operations research and optimization algorithms, in particular to a multi-mode time optimization scheduling method for steelmaking and continuous casting production lines. technical background [0002] The steelmaking and continuous casting production process is the core process in the production process of iron and steel enterprises, mainly involving the integrated operation plan of the three major processes of steelmaking, refining and continuous casting. The molten iron produced in the blast furnace is pretreated and transported to the steelmaking plant by torpedo truck, then mixed with scrap steel and smelted into high-temperature molten steel by converter, and then passed through the refining furnace for argon blowing and stirring, alloy addition, vacuum degassing and other external refining treatments. To meet the chemical composition and temperature requirements of the molt...
