Forged Steel Work Roll for Cold Rolling Mill

The forged steel work roll is solid-forged roll made of alloyed steel, close to eutectoid and hypereutectoid steel. It owns a good combination with hardened surface which creates a strengthened working layer, heat check and tough core resistance to breakage. Heat treatment reduces and equalizes residual internal stress.

The work roll can be used for cold rolling mill. The forged rolls are produced by steel-making, refining and forging. A homogenous highly dispersed structure provides mechanical properties of the internal layer for complicated heat treatment. It becomes easier for exceptional performance by using the forged rolls which are applied in cold rolling mill.
