Continuous casting coordinated optimization control method

Abstract

The invention discloses a continuous casting coordinated optimization control method. The continuous casting coordinated optimization control method comprises the steps of casting blank quality large closed-loop control, coordinated optimization control and bottom layer small closed-loop control, the design concept of optimizing control is adopted, zero defect in quality of a continuous casting billet is taken as restriction, technological parameters in a continuous casting process are optimized, sequential control logic is coordinated, and an optimization calculation result is issued to each bottom layer controller to be executed, so that optimal coordinated control of a continuous casting production process is realized, productivity is steadily improved while product quality is guaranteed, and energy consumption and water consumption are reduced at the same time.

Description

technical field [0001] The invention belongs to the technical field of advanced industrial manufacturing control, and in particular relates to a continuous casting coordinated optimization control method. Background technique [0002] With the reform of the domestic steel supply side, the capacity reduction of steel must rely on artificial intelligence and big data technology as a tool to reduce the production and operation costs of enterprises by realizing the intelligent and lean production of the continuous casting process. This is the inevitable way out for the development of steel enterprises . And cost control is nothing more than increasing income and reducing expenditure on the premise of ensuring product quality. [0003] The quality control of continuous casting slabs has always been the focus of attention of people in the industry, but due to the complexity and difficulty of its technology, no effective progress has been made. When the billet quality problem is ...

And cost control is nothing more than to increase revenue and reduce expenditure on the premise of ensuring product quality.

[0003] The quality control of continuous casting slabs has always been the focus of attention in the industry, but due to the complexity and difficulty of its technology, no effective progress has been made

When the billet quality problem is not effectively resolved, quality incidents occur frequently, the production efficiency of the continuous casting machine will also be affected, and the production capacity will be restrained
