Mass Flow, Automatic Gauge Control (AGC) is a technique used for many years to control strip thickness in Tandem Cold Rolling Mills. It enables tighter control of thickness by providing faster and more accurate control of the roll gap. Utilizing Mass Flow AGC control techniques permit operations to achieve specified thick-Menghui and his colleagues in 2007 in research about control in hydraulic AGC of cold rolling mill used the cascade predictive control by the combination of PID control for the HAGC and dynamic matrix control for the inner loop of the screw-down servo system. This method can hardly solve the problem of gaining the step response of the whole HAGC.

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 hotCold Rolling Mills 4-Hi/6-Hi Reversing Cold Mills Magadh can offer 4-Hi/6-Hi reversing cold mills in single stand or twin stand configuration for strip width up to 1650 mm, minimum finish strip thickness up to 0.15 mm and mill speeds up to 1400 MPM. State of the art level 2 / level 3 automation and controls with Mill Management System.

types of Automatic Gauge Control (AGC) methods have been developed for hot or cold mill processes. The Brit-ish 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].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.

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)

Thickness precision is one of the most important quality indexes in strip rolling process [2, 3].Monitor automatic gauge control (AGC) based on hydraulic roll gap control system is widely used in modern strip rolling mills [4–7].In monitor AGC system, gauge meter is used to measure strip gauge derivation, which is installed at the delivery side of the finishing mill.02 Magadh has wide range of Cold rolling mills to suit 02 varied application and requirements. 4 HI MILLS 20 HI MILLS 6 HI MILLS GAUGE & SHAPE CONTROL SYSTEMS TENSION REEL MANDRELS DISCLAIMER PRODUCT, PRODUCT SPECIFICATIONS AND DATA ARE SUBJECT TO CHANGE WITHOUT NOTICE TO IMPROVE RELIABILITY, FUNCTION OR DESIGN OR OTHERWISE.
