【Abstract】 This paper decribes the constitution and the features of the hydraulic screw-down control system by direct measurement of the roll gap. It puts forward a simplified model for the cylinder and load on the system, so the transfer functions of the cylinder, the load and the overall system are derived. Taking a hydraulic four-roll mill with diameter of 350mm the theoretical calculations and the test results of the system characteristics are discussed.更多还原
