A control method for hot rolling rolling stock preparation in slab warehouse

Abstract

The invention provides a control method for hot rolling material preparation in a slab warehouse, which includes: obtaining hot rolling plan slab information, slab information in the slab library, stacking position information and material preparation requirement information in the slab library; determining The initial material preparation control plan and its corresponding crane instructions; the tabu search method is used to optimize the initial material preparation control plan; the hot rolling plan material preparation is carried out through crane operation according to the final material preparation control plan obtained after optimization. The method of the present invention improves the work efficiency of driving material preparation and reduces the logistics cost of slab warehouse by reducing the number of stacking times; by reducing the moving distance of the crane, it improves the efficiency of the crane and reduces the preparation time; by improving the placement of the stacked slabs The regularity improves the space utilization efficiency of the slab warehouse, which not only meets the safety requirements in the slab warehouse, but also speeds up the efficiency of slab circulation and reduces logistics costs.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method for controlling hot rolling stock preparation in a slab warehouse. Background technique [0002] At present, the production process of general iron and steel enterprises is as follows: figure 1 As shown, the slab is produced as a semi-finished product in the continuous casting process, and then stored in the slab warehouse. As a buffer link between steelmaking-continuous casting and hot rolling, the slab warehouse plays a vital role in coordinating the capacity of steelmaking and rolling and maintaining the balance of the entire production process. The logistics operation of the slab warehouse mainly includes operations such as slab storage, material preparation and delivery, and the crane is responsible for performing all operations. The stacking operation is always accompanied by the removal operation of the demand slab. When the demand slab is ready to be remov...

Problems solved by technology

When implementing the material preparation plan, the management personnel of the warehouse area extract the planned slabs in the reverse order of the batch order of the hot rolling plan, and put the planned slabs into the feeding area in turn. During the material preparation process, if there are The slab is covered and stacked: if it is poured into a stack containing other required slabs, then the slab may be stacked again; if it is poured away from the stack where the demanded slab will be removed , the crane needs to move a long distance, prolonging the material preparation time, and affecting the production rhythm of hot rolling; if it is poured into a stack where the slabs are placed chaotically, the chaos of the stack will increase, and slabs of different specifications Mixed piles, especially when slabs with large size differences are piled up in one pile, collapse accidents are likely to occur if they are handled, and the chaotic arrangement of slabs increases the difficulty and cost of warehouse logistics management
