Problems solved by technology

[0005] The rolling schedule optimization methods involved in the above-mentioned public documents all carry out optimized setting calculations on the parameters of the rolling process, taking a lot of constraints of the rolling mill itself into account, but not enough consideration of the constraints related to the process and empirical constraints, so Compared with the actual production process, there are large differences

Abstract

A rolling method and a device for strip steel tandem cold rolling belong to the technical field of metallurgical process control. Based on site conditions of the strip steel tandem cold rolling practical production, the rolling method and the device for the strip steel tandem cold rolling fully consider reasonability of optimization calculation of rolling force, select lowest energy consumption as an optimization goal, adopt a large number of constraint conditions in the practical rolling production process, utilize an improved particle swarm optimization (PSO) optimization algorithm to carry out optimal calculation on the basis of rolling mechanism relationship, and can quickly calculate out optimized rolling schedule information to avoid extra cost caused by lack of comprehensive consideration of experience rules. By means of the rolling method and the device for the strip steel tandem cold rolling, full play to the production capacity of the whole tandem cold rolling system can be given, product quality is improved, total power of a motor of a rolling mill is reduced simultaneously, and energy saving and consumption reduction are achieved accordingly.

Description

technical field [0001] The invention belongs to the technical field of metallurgical process control, and in particular relates to a strip steel cold tandem rolling method and device. Background technique [0002] With the improvement of people's living standards and material needs, cold-rolled strip steel, a high value-added product, has become an indispensable raw material for all walks of life due to its excellent mechanical properties, process properties and surface quality. People's requirements for it Also getting higher and higher. The strip cold rolling system is mainly composed of the following parts: uncoiling, welding, straightening, pickling, cold rolling, shearing, winding, etc. The control system of each part is very complex, and the quality of their control performance will affect the final product quality. [0003] Therefore, how to determine the optimized rolling plan for the strip cold rolling process is of great significance to the actual production. Op...
