Hot Roll Mill Hydraulic System

Modeling and Identification of Hydraulic System on Rolling

01-07-1994· Rolling mills, Nonlinear systems, Closed loop systems, Hydraulic systemll, System identification 1. INTRODUCTION The purpose of this paper is to derive a model and perform a system identification of the hydraulic system on the hot rolling mill at The Danish Steel­works Ltd in Frederiksvrerk, Denmark.

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.

18 Roll Hydraulic Rolling Mill Hani Tech

18 Roll Hydraulic Rolling Mill 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. The rolling mill is suitable for processing stainless steel, carbon steel and non-ferrous metal strips.

31-03-2015· ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hot-strip rolling mill in Duisburg. The animation shows how it all works.

Modelling of the hydraulic work roll bending control

For modern hot rolling mills the typical hydraulic circuit was designed to control the roll bending force during rolling process. The most common operating modes of the roll bending system were studied: rolling, start and stop. The bending roll control system was designed in the form of functional blocks, connecting the actuators, sensors and sided subsystems of the rolling control.

Nonlinear Hydraulic Gap Control: A Practical Approach

01-06-2000· Modern rolling mills contain several feedback loops and the roll gap is usually adjusted by a hydraulic system. Since the HGC is part of the most inner control loop in this cascaded structure, the use of a controller with high dynamics for the hydraulic positioning system is essential due to performance considerations.
