cold rolling mill is of the type where shifting of both first intermediate and inner second intermediate rolls are possible. The rolls are numbered and defined as: 1. Work roll, diameter between 50-75 mm. 2. First intermediate roll (tapered), diameter between 90-105 mm. 3. Inner second intermediate roll (CVC roll), diameter between 177-182 mm. 4.

Practical Roll Techniques - Grinding & Balancing

This paper provides practical tips on roll inspections, balancing, grinding and grooving. In addition, we discuss proper roll handling during removal, storage, transport, and reinstallation. Finally, ceramic roll conditioning is discussed. It allows for returning the roll to its original finish while the roll is still in the machine.
