Embodiment Construction

[0031] The steelmaking-continuous casting plan is due to the fact that the final contract (or converted production contract) demand is multi-variety and small batch, and the organization of production is based on a fixed batch (heat plan) and a certain amount of economical production to save adjustment time and save preparation costs. Batch (casting plan) is carried out, which requires the best combination of different contract requirements according to the limitations of the process. This type of problem belongs to the problem of production batch planning. Steelmaking-continuous casting plans are divided into two types: One is the furnace plan (Chargeplan); the other is the pouring plan (CAST plan).

[0032] 1. Heat plan

[0033] It belongs to the production batch plan of the steelmaking-continuous casting stage. In the steelmaking-continuous casting production stage, due to the demand of the intermediate contract (hot-rolled slab) or the final contract (such as hot-rolled st...

Abstract

The invention relates to an industrial process optimization control method for steelmaking and continuous casting. Firstly, a heuristic algorithm is used to solve the initial heat planning and cast planning; and then the initial plan is used as the starting point of the solution space, and the same width selection and steel species order are used as the neighborhood structure. In each neighborhoodstructure, exchange and insertion of short plates and long plates, exchange of slabs in the short plates, tail slab deletion of the long plates or optimization of the production operation are carriedout; by a variable neighborhood search method, local optimum heat planning and cast planning are solved, the neighborhood structure is replaced, the search range is widened, and the next local optimum heating planning and cast planning are solved; and when all neighborhood structures find local optimum heat planning and cast planning, the highest KPI index value is taken as the final heat and cast planning. By the method of the invention, the optimization level of the steel-making and continuous casting plans can be raised to ensure that the iron and steel enterprises obtain the maximum profit.

Description

technical field [0001] The invention belongs to the technical field of steelmaking and continuous casting, and in particular relates to an industrial process optimization control method for steelmaking and continuous casting. Background technique [0002] Modern iron and steel enterprises usually adopt the integrated production mode of steelmaking-continuous casting-hot rolling, and the steelmaking-continuous casting link, as the pre-order link of the process, plays a vital role in the entire production process. However, the large-scale production mode of iron and steel enterprises has formed a contradiction with the customer's small-batch customization requirements. In order to solve this contradiction, it is necessary to improve the optimization level of steelmaking-continuous casting plan to ensure the maximum profit of iron and steel enterprises. [0003] The steelmaking-continuous casting plan is due to the final contract or the converted production contract, the deman...
