Abstract

A furnace group optimizing method and a system for cold-rolling bell annealing furnace sets belong to the field of steel material processing information technology. The method comprises the following steps of: (1) according to practical technological parameters, performing priority settings on coiled sheets to be annealed; (2) furnace pre-grouping: arranging coiled sheets according to priority penalty values in ascending order; placing the coiled sheet with the minimum priority into a furnace according to the coiled sheet-furnace matching criteria; according to the coiled sheet-coiled sheet matching criteria, selecting, from the residual coiled sheets, coiled sheets that can form a furnace group with the coiled sheet in the furnace sequentially, and when the height reaches the maximum height of the bell furnace, forming a furnace grouping scheme; repeating the procedure until the demanded furnace group scale is formed; (3) adjusting the initial feasible furnace grouping scheme; and (4) using the developed system to upload the obtained optimized furnace grouping scheme to the manufacture execution system for implementation. The method and the system of the invention increase the productivity of the bell furnace set, improve the annealing quantity of the coiled sheets and effectively lower the consumption of energy resources such as hydrogen, nitrogen, water, coal and power, etc.

Description

technical field [0001] The invention belongs to the technical field of iron and steel material processing information, relates to automation technology, and in particular relates to a bell-type annealing furnace unit optimization furnace assembly method. Background technique [0002] Cold-rolled products are high value-added products, which play a key role in improving the economic benefits of enterprises and are also an important production link in iron and steel enterprises. How to use existing resources to save energy and reduce consumption, reduce production costs and improve economic benefits has become a problem faced by many enterprises. Annealing is a process for the production of cold-rolled products. It is a necessary process for most metallurgical enterprises to produce high-quality cold-rolled products. According to the different materials and workpiece sizes, different holding times are used, and then slowly cooled, the purpose is to make the metal inside The o...
