Rolling Mill

Perantech sees itself as a contact for the entire life cycle of steel and offers technical solutions for its production and processing. In addition to all these production processes, rolling mills play an important role in the manufacture of the final product. In these plants, the thickness of the workpiece is reduced and the length is increased by plastic deformation. The main components include a stable roll housing, a roller table system, a descaling system, a shear for cutting the workpiece, work and back-up rolls, and other equipment such as gears and motors. To ensure that the customer can always operate efficient rolling mills, Perantech strives to supply quality equipment.


Due to the high production rate and good quality control of the final product, hot rolling mills are the most commonly used forming process. In these plants, the raw material is processed into thin sheets, plates and various types of cross-sections such as round, flat, square and angle steels, channels, T-sections, rails and beams. In these processes, rolls provide thickness reduction by plastically deforming the metals through high compressive forces. This results in an increase in width and length and a changed cross-section while maintaining the same volume.  Hot rolling mills require raw material of the right weight, size and thickness, which is preheated to 1200°C in preheating furnaces. After heating, the material reacts with oxygen to form mill scale, which must be removed by high-pressure water jets before rough rolling. In addition to a significant reduction in material thickness, the roughing mills further clean the scale. The materials are then transported to the finishing mills for product finishing and coiling.
