This 1450mm 20 Hi Reversible Cold Rolling Mill was designed to roll 1.0~3.0mm plain carbon steel, low alloy steel and 200, 300,400 series. stainless steel board into 0.2-1.2mm thick as clients'requirement. The model has flexible rolling process, and it can adapt to changing raw materials.
Rolling mills are not a standard machine tool, nor are they built for stock. They are designed and built-to-order to specifically accomplish an end product or process. At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills and blooming mills.
The control of continuous tandem cold rolling of metal strip is similar to the control of stand-alone tandem cold rolling except that additional challenges occur during the passage of the weld ...

20Hi ZR Mill, HZ Mill. The ZR mill uses ultra-small diameter work rolls to efficiently roll high-hardness materials such as stainless steel, electrical steel strip, and phosphor bronze. To the original high rolling reduction capacity of the mill, we have added the double AS-U (shape control mechanism) originally developed by our company.
The 20 high rolling mill from ANDRITZ Sundwig is mainly used for cold rolling of metal strip to thinnest final gages and wide range of strip width. The special feature in a 20 high mill is the relation between work roll diameter and barrel length.

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. In this paper, we design PI controller in outer loop for the strip exit …
The article describes recent advances on 20-hi cluster mill optimization. The 20-hi mill is a. precision mill which has be en widely applied to thin and/or high strength mate rial rolling. Studies ...
One can see in the figure that, while the PC mill has the strongest crown control capacity in all of the width ranges, the HC mill is effective for narrow strips, particularly due to the quick response of the roll benders. Initially, the HC mill was applied to the cold rolling mills, and then to the finishing mill stands of the continuous hot
Honeywell's Automatic Gauge Control (AGC) and Hydraulic Gap Control (HGC), incorporated with the MetalsMaster gauging system, enable mills to deliver the right gauge thickness with the least product variation. It also offers Target Adaptive control to increase yield, improve product quality and reduce scrap.
Automatic rolling process is a high-speed system which always requires high-speed 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 2-level control …
maximum rolling speed of a cold or foil mill, 8 meters of strip is produced. It is easy to see why Automatic Gauge Control (AGC) is an essential component of modern rolling mills. Comprehensive AGC algorithms incorporate readings from dozens of sensors around the mill. Some of the key AGC input parameters are speed and tension. (See Figure 1)
simulator was expanded to the AGC for a single-stand 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
Fundamental study on automatic gauge control (AGC) of reversing cold rolling mill was carried out. The study includes the method of evaluating performance of AGC system and designing a control system according to the results of the study. It was concluded that the response of AGC system depends on the dy-
MetalsMaster™ AGC Automatic Guage Control Product Information Note Improve your business performance in today's challenging economic environment - Honeywell's MetalsMaster™ has integrated automation solutions for aluminum sheet and foil rolling to help achieve faster rolling speeds, tighter gauge quality control and
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, mill-springit through rolling mill.
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.
