Download Tandem Cold Metal Rolling Mill Control books, This book deals with a novel and practical advanced method for control of tandem cold metal rolling processes based on the emerging state-dependent Riccati equation technique. After a short history of tandem cold rolling, various types of cold rolling processes are described.
Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area …
Rolling Mill Tutorial. Before continuing, make sure you have read Chapter 5. System Description. Another control problem (besides the continuous caster) arising in the steel industry is the control of the exit steel thickness in a rolling mill. The diagram below shows the layout of a rolling mill…
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.
Precision control of length of cut of rolling stock by cropping shear after roughing mill results in reduction in waste and increase in mill yield. In addition to the higher rate of production in a given time, different grades of steel can be rolled because each grade has its own mill setup coming from the automation system, increased plant ...

Tandem cold rolling process is a nonlinear complex system with external and internal uncertainties and significant disturbances. The improvement in the quality of the final output depends on the control strategy of centerline thickness and interstand tension. This paper focuses on interstand tension control problem in 5-stand tandem cold rolling mills.
