Plate and strip rolling process quality comprehensive prediction and process regulation and control method

The invention discloses a plate and strip rolling process quality comprehensive prediction and process regulation and control method which comprises the following steps: collecting and storing rolling process data to obtain a database; constructing a rolling mechanism model based on a strip steel deformation mechanism; establishing a self-learning model of mechanism fusion data, and performing plate shape detection and calculation to obtain a plate shape measurement result; and designing a plate shape compensation controller based on GA-BP, and performing plate shape compensation control through the plate shape compensation controller based on a plate shape measurement result. According to the method, the mathematical model for describing the strip shape parameter evolution behavior of the strip steel in the rolling and cooling process is established, a certain strip shape quantity is obtained in the finish rolling process so as to compensate the strip shape defect after cooling, and the ...
