In rolling mill, the accuracy and quality of the strip exit hickness aret 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
As regards "abnormal" rolling conditions which are more or less very "normal" for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll

Rolling processes 51 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

1 HOT ROLLING PRACTICE – An Attempted Recollection Saral Dutta. B. Tech. (Hons.), Executive Director, ISP RMD, SAIL (Retired) Rolling is a metal forming process in which metal stock is passed through a pair of rolls.
The rolling process is shown in Fig. : Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

*) A Sendzimir mill is a mill with small diameter work rolls, each backed up by two rolls of larger diameter which are in turn jointly backed up by a cluster of three rolls. This mill configuration is often used for heightstrength and stainless steel. Factbox 1 ABB and rolling mills Footnote 1) A pass is one deformation step consisting of the
Rolling mills have many different designs and may be standalone pieces of equipment used for processing plate or ingot, or incorporated into full processing lines used for coiltocoil processing. To ensure outgoing material gauge meets a required dimensional tolerance, a rolling mill typically has very accurate positioning feedback.
For all kinds of rolling mills, whether roughing mill, hot rolling mill, or finishing mill, rolling is the simplest method of shaping steel. In this process, materials are being passed between two rolls, named work rolls. The rolls rotated at the same speed but in opposite direction; clockwise and counterclockwise.
