Product Overview
Intermediate rolls sit between work rolls and back-up rolls in multi-roll mill configurations such as 6-Hi and 20-Hi mills. They enable precise strip flatness and crown control — essential for the production of thin-gauge, high-strength steel strip. VSAG sources intermediate rolls optimised for axial shift capability, wear distribution, and surface quality maintenance.
