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.

The strengths of the QR48 rolling mill are:: il the fast change of work cylinders, which can be replaced by hand in just 15 minutes, without using particular equipment;; the four high configuration, also used in the QR65 mono-stand rolling mill.; This model also includes: : the possibility of carrying out operations on reduced lengths or on rolls using the reversible mode;

A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.

2 High Rolling Mill - Element. 2 High Rolling Mill. Rolling mills consisting of two rolls or known as a 2 High rolling mill is used for anything from temper pass to breakdown of material.
