Blooming, Roughing & Universal Mill Rolls
Manufactured for heavy structural and breakdown stands, these rolls utilize alloy cast steel, semi-steel, or alloy nodular iron compositions engineered to endure severe rolling torque, bite impacts, and high mechanical reductions. Solid casting or composite centrifugal methods are selected based on stand loading profiles to address roll body stress concentrations.
