Abstract

The invention relates to an integrated control method and a device of production operations of a heating furnace and hot rolling of an iron and steel enterprise, belonging to the technical field of iron and steel metallurgy. The integrated control method comprises the following steps: firstly establishing a production operation model of hot rolling and the production operation model of the heating furnace, and utilizing the intelligent optimization algorithm to determine the initial production operations; evaluating and analyzing the obtained production operation schemes; carrying out feedback on the evaluation and analysis results through the closed loop control strategy, amending the production operation schemes, and finally determining the integrated control scheme complying with the conditions of the production operations of the heating furnace and hot rolling process step. The integrated control method adopts the closed loop control strategy for integrating the heating furnace and the hot rolling process step, thereby being capable of avoiding the constrain that the existing method is easy to cause the local optimization to a great extent, also effectively solving the outstanding conflicts and problems in the current actual production and realizing the integrated control and the optimization of production operation plans of the heating furnace and the hot rolling.

Description

technical field

[0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to an integrated control method and device for heating furnaces and hot rolling production operations in iron and steel enterprises. Background technique

[0002] Hot-rolled strip steel is the most important steel product, accounting for more than half of the entire steel product, and is an important factor to measure the development level of a country's steel production. Heating furnace and hot rolling production play an important role in the entire production process of iron and steel enterprises. On the one hand, the hot-rolled coils produced by the hot rolling process can be directly sold as finished products, and on the other hand, they can be used for various production processes in the downstream finishing stage. Provide raw materials.

[0003] The production process of the hot rolling mill of the iron and steel enterprise is as follows: figure...
