Jan 26, 2015· Usually Cold Rolling is done at ambient temperature. Cold rolling is a process of reducing thickness of metallic strips by passingCold rolling is a process of reducing thickness of metallic strips by passing it through rolling mill. The rolling mill consists mainly of rolls drives, bearings, millspringit through rolling mill.
Improved AGC Control using adaptive technique in Cold Rolling Mill (pdf 616kB) Selftuning control in Cold Rolling Mills The major difficulty in strip thickness control is the high speed combined with changing strip qaulities and the high accuracy that is required.
There is a growing demand for high accuracy in thickness control in metal rolling area. If the required accuracy of hot rolling mills can be achieved, then in some cases, cold rolling is not even required, which can result in a radical decrease of production costs. The schematic structure of a typical aluminum hot reversing rolling mill can be
in cold rolling using the selfadaptive AGC 2000X control system, developed by First Control. Longterm production experience from two installations will be shown, a new 12high Mitsubishi cold rolling mill and an old Sendzimir mill. The improvements with selfadaptive control methods compared to conventional AGC control can be judge to at least
highspeed data loggers such as IBA Experion MetalsMaster™ systems are designed for highperformance automation of aluminum rolling mills. Honeywell has combined entry and exit thickness measurements, Automatic Gauge Control (AGC), Hydraulic Gap Control (HGC), Online Alloy Compensation, Mass Flow Control (MFC) and other enhancements such as roll
simulator was expanded to the AGC for a singlestand cold rolling mill and the automatic elongation control (AEC) for a skin pass mill, and these applications led to studies of product dimension control (thickness and elongation) for various other sheet rolling mills of the company. As a result of the studies, a technique to automatically identify

Nov 17, 2006· The highspeed tandem cold rolling mill is the typical complicated electromechanical system. Since the request to the quality of cold rolling sheet strips is higher and higher, the control system of the tandem cold rolling mill becomes more and more precise and intellective. And the feedforward control system of the hydraulic AGC is its important .
Nov 12, 2013· types of Automatic Gauge Control (AGC) methods have been developed for hot or cold mill processes. The British Iron and SteelResearch Association (B1SRA) AGC method based on the gaug meter principle and the feede forward AGC method using the delivery time of the strip have been widely utilized in steel rolling mills [3].
