Research and practice of multi furnace to multi machine production scheduling model in steelmaking plants
In order to further improve the intelligent manufacturing level of production planning and scheduling at Laiwu Iron and Steel Group Yinshan Steelmaking Plant,a systematic study was conduc-ted on the complex scheduling plan of 4 furnaces,4 machines,and non matching furnace machines.By analyzing the operation cycle and production operation mode of the steelmaking refining continu-ous casting process,four bottom level matching principles were explored and summarized,including the dynamic total balance principle,furnace machine matching principle,non interrupted pouring principle,and space proximity principle.Based on the four principles of matching logic,a furnace ma-chine matching scheduling model was established,which achieved automatic scheduling of steelmak-ing plans for multiple furnaces to multiple machines in the non matching state of the furnace ma-chine.This ended the production scheduling mode that was completely centered on dispatchers and driven by manual experience,greatly improving scheduling efficiency and planning accuracy.In addi-tion,the dynamic scheduling model of the furnace machine based on the matching logic of the four principles has strong flexibility and universality,and can be applied to more steel enterprises.
