Long product rolling mills are one of the most demanding applications for motor drives. The rolling process consists of passing a hot steel billet through a "rolling mill", also called a "rolling train". The modern rolling train consists of multiple rolling stands arranged in an in-line configuration.

Most of the deformation source in hot strip rolling is in the adhesion zone, where the contact stress depends on the resistance to pure shear. If this finding is taken into account, the rolling force and power may be calculated with much greater accuracy. On that basis, effective operating conditions for broad-strip mills may be developed.
