Four high rolling mills. Cluster rolling mills. Planetary rolling mills. Tendem or Continuous mills. 1. Two High Rolling Mills. It contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor.
modern rolling mills, and specially cold tandem mills with high productivity, are equipped with a number of transducers participating in automatic control systems: rolling force (on exception rolling torques), strip tensions between stands, average gauge and thickness profile at exit, strip tension profile (shape measuring systems) between …
#1) Two high reversing mills In two high reversing mills, the rotation of rollers occurs in forward direction as well as reverse direction. Firstly, the rollers rotate in one direction and then they rotate in opposite directions so that the metal can pass several times in the back and forth direction through the rollers.

a control system for a rolling mill having a pair of housings, at least two rolls supported at their ends within said housings with a gap defined between said rolls, and a pair of hydraulic cylinders respectively operatively associated with said pair of housings for varying said gap defined between said rolls in order to prevent abnormal effects …
Mill rolls are driven by large several thousand horsepower motors. Rolling mills are computer controlled with complex automated drive systems. Overall, rolling mill equipment is expensive and can take a long time to repair or replace, even when slight damage occurs. Types of mills include blooming, bar, rod, plate and strip mills.
Rolling mill controls generally are concerned with effecting a change in the roll setting as a function of a change in the rolling pressure. Prior patents that, at least in part, envision such a control are U. S. Pat. No. 2,726,541 that issued to R. B. Sims on Dec. 13, 1955 and No. 3,496,743 that issued to M. D. Stone on Feb. 24, 1970.
a rolling mill and associated control system are described, including means for adjusting roll spacing of the mill to keep the exit gage of rolled strip substantially constant as the mill is accelerated to normal operating speed; the adjusting means being operable selectively over a range of mill speeds to cause roll spacing adjustments in …
Advanced Process and Quality Control in Hot Rolling Mills Using Eddy Current Inspection Autor: SVEN KLING Speaker: Markus WITTE PRÜFTECHNIK NDT Ismaning, Germany +49 89 99 616 152 markus.witte@pruftechnik Abstract Eddy current testing is a common method for the surface inspection of semi-finished products.
The control of rolling is done by a machine, or rolling mill. From a control point of view it is necessary to study the combined behavior of machine and metal deformation to find the variables that may be used to most effectively regulate the process. A typical problem in this area is to control the output thick-
Cold rolling mill control systems; Cold rolling mill control systems. By using meticulous auto-control and abundant monitoring and recovery functions, these systems achieve the world's highest quality level as they control steel thickness, tension, and shape through the adoption of advanced control theory while also promoting stable operations. ...
Thermo mechanical controlled processing (TMCP) is a technique designed to improve the mechanical properties of materials by controlling the hot-deformation process in a rolling mill. This was originally designed to produce …
Rolling mill consists of rolls, bearings, structure, or housing for rigidly supporting these parts, power drive, power transmission system, speed control, roll gap adjusting set up, etc. The force for rolling generally is very high. The power requirements are very high. Hence initial capital investment is high.
