A method and system for reducing the stacking volume of hot-rolled slab warehouses in iron and steel enterprises

Abstract

The present invention provides a method and system for reducing the stacking amount of hot-rolled slabs in a steel enterprise. By obtaining the original process data of the hot-rolling production process, and based on the original process data of the hot-rolling production process, the hot-rolling pre-planned slab and the Alternative rules for other candidate slabs in the library area, establish a mathematical model to describe the impact of hot rolling pre-planned slab selection on slab stacking in the material preparation process, and use the decentralized search method to formulate and reduce slab stacking in the hot rolling plan preparation process The optimization plan of quantity ensures the smooth production rhythm of upstream and downstream processes, improves the effective material preparation efficiency of cranes, reduces the energy consumption of dry heating furnaces, optimizes logistics, saves energy, reduces costs and increases production capacity.

Description

Technical field: [0001] The invention relates to the technical field of operation management information in warehouse areas of iron and steel enterprises, in particular to a method and system for reducing the amount of stacking of hot-rolled slab warehouses in iron and steel enterprises. Background technique: [0002] In the iron and steel industry, the finished slabs from the steelmaking-continuous casting process are stored in the hot-rolling front warehouse in the form of stacks, and the slabs programmed into the hot-rolling plan in the storage area are extracted and moved out of the hot-rolling front warehouse (slab warehouse ), sent to the heating furnace for heating, and then into the hot rolling production line for rolling processing. As a buffer link connecting the two processes of steelmaking-continuous casting and hot rolling, the warehouse before hot rolling is not only the storage area for the finished products of the steelmaking-continuous casting process, but a...

AI Technical Summary

Problems solved by technology

The cumbersome order requirements and complex hot rolling procedures make it difficult to take into account the actual stacking position of the selected planned slabs during the manual production scheduling process

After the hot-rolling plan is released to the storage area, because the hot-rolling schedule does not take into account the storage location of the target slab, the target slab may be accessed due to unplanned slabs stacked on the upper layer of the target slab during the hot-rolling preparation process The large number of necessary inversions required by the billet

A large number of stacking operations lead to low efficiency of hot rolling stock preparation, and even cause loss of energy consumption due to untimely hot rolling stock preparation and loss of production capacity caused by empty heating of the hot rolling mill
