Jul 01, 1994· The rolling mill is in operation at The Danish Steelworks Ltd. in Frederiksværk, Denmark. The hydraulic system is used forthickness control of the rolled plates. A non linear model for the system is derived and transformed to discrete time. The data are collected during normal operation, which implies that the system is operating in closed loop.

Mill stiffness is an important parameter for strip rolling mill, but it is difficult to onlineUsed the first method, many strips in different thicknessIn the cold strip steel rolling process, a large number of real-time data areis connected to hydraulic cylinder body through spherical pads, and the . force in incremental form was:.
hydraulics of rolling mill Our Purpose And Belief L&M Heavy Industry is committed to provide the global customers with the first-class products and superior service, striving to maximize and optimize the interests and values of the customers, and build bright future with high quality.
In order to improve the disturbance rejection ability and tracking accuracy of the hydraulic servo system of the rolling mill, this study combines nonsingular terminal sliding mode control (NTSMC) with active disturbance rejection control (ADRC). A fourth-order extended state observer was designed to estimate the disturbance of the system in real time.
Accurate and precise position control and pressure control can be realized by the hydraulic cylinder in the modern rolling mill. Therefore, the appropriate control strategy should be adopted. From the control engineering point of view, it is necessary to achieve the rejection of external disturbances and an effective reference tracking for the step, as well as a ramp and …

hydraulics of rolling mill Autogas-Benda. 18 Roll Hydraulic Rolling Mill Cold Rolling Mill- Hani Tech. There are two types of 18-roll hydraulic rolling mill—-Z-high type and S-high type, in which 4 sets of side support devices are added to the HC six roll mill.
Correct mill stand geometry is essential for effective and accurate gauge control, strip/plate quality and maintenance of the mill and its associated parts, like bearings, chocks, hydraulic clamps, bending and balancing systems as well as gauge control systems. Housing windows of new mills create a stable and accurate location for roll chocks.
In this article the AGC (Automated Gauge Control) system, of a hot rolling mill is analyzed and different methods are described to improve its performance. The mill stretch compensation and other disturbances during the rolling process are compensated and a rolling speed dependent, adaptive PI controller is developed to accomplish fine thickness control.
