Abstract
The invention provides a hot rolling mill rolling control system used for improving rolling accuracy, and relates to a hot rolling mill control system. The hot rolling mill rolling control system used for improving rolling accuracy solves the problems that an existing hot rolling mill control system can not realize constant roll bit rolling under manual control, so that control accuracy is low. The hot rolling mill rolling control system used for improving rolling accuracy can detect the displacement of a piston inside a hydraulic cylinder through a displacement sensor, and compares detected displacement signals with roll bit control signals to obtain a displacement difference, a servo valve carries out conversion between electrical signals and flow signals on the received displacement difference, oil feeding amount of an oil tank to the hydraulic cylinder is controlled, the displacement of the piston of the hydraulic cylinder is further accurately controlled, constant roll bit rolling is finally achieved, and the rolling accuracy of a hot rolling mill is improved by 40%.
