On-line flatness measurement of large steel ... - VTT research

A flatness disturbance can be produced at a hot strip mill by a mismatch between the work roll profile and the incoming strip thickness profile. This will produce a non-uniform reduction across the width of the strip, leading to a non-uniform elongation of the strip in the direction of rolling (Heaven 1988).
