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 .
Automatic rolling process is a highspeed system which always requires highspeed control and communication capabilities. Meanwhile, it is also a typical complex electromechanical system; distributed control has become the mainstream of computer control system for rolling mill. Generally, the control system adopts the 2level control structure#x2014;basic automation .
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
rolling equipment and operation techniques in cold rolling, such as the advent of the fully continuous mill, new techniques for automatic gauge control especially in threading, the rolling of high tensile strength steel, effective shape control devices, energy saving in rolling.
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
In rolling mill, the accuracy and quality of the strip exit thickness are very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control (AGC) system is used. Because of roll eccentricity in backup rolls, the exit thickness deviates periodically.
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
