Method and system for reducing stack transfer amount of hot rolled slab warehouse of iron and steel enterprise

Abstract

The invention provides a method and system for reducing the stack transfer amount of a hot rolled slab warehouse of an iron and steel enterprise. The method comprises the steps that original technological data in the hot rolling production process are obtained; according to the original technological data in the hot rolling production process, replaceable rules of hot rolled preplanned slabs and other candidate slabs in the warehouse area are established, and a mathematical model used for describing the influence by selection of the hot rolled preplanned slabs on slab stack transfer in the material preparation process is established; the optimization scheme of reducing the slab stack transfer amount in the hot rolling planned material preparation process is formulated by the adoption of a scattering searching method. In this way, smooth production rhythm of upstream and downstream procedures is guaranteed, the efficiency of a crane for effective material preparation is improved, the empty combustion energy consumption of a heating furnace is lowered, physical distribution is optimized, energy is saved, the cost is reduced, and productivity is improved.

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
