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. Tension dynamics …

In Table 2, the mark "Cr 50" denotes the difference in the sheet thickness (sheet …
Keep ReadingThe paper describes the design of a dynamic control scheme for thickness and tension for a tandem rolling mill. Using simple matrix theory, circuits are derived which compensate for predictable variations in plant characteristics, caused by changes in rolling conditions, and decouple the thickness and tension signals.
