Forged Rolls for Roughing Stands for Long Products Mills. Forged rolls may be used in rolling processes with higher demands of mechanical resistance. These products show extremely homogenous structures capable of facing the most severe rolling conditions as well as the demands of the sectionmills and, particularly, the heaviest ones.

Roughing Intermediate Rolls. Stands situated from the beginning of the mill, where the stock temperature is high and the bar speed is low, the contact time and contact angle are therefore high and require a different material than later stands. The wear mechanism in roughing is predominantly thermal, resulting in firecracking and a poor suface.
