Tension leveller model for optimised strip exit flatness

Tension levellers are used after a rolling mill to correct some of the off flatness caused by the rolling process Mills may have flatness control systems to help mill operators minimise sheet defects from the rolling process but some levelling is usually required to produce extremely flat sheet that some customers now demand for their processes.
