Roller for Steel Rolling Mill Forged Mill Roll
Products Description
Centrifugally cast compound steel back -up rolls have a shell of cast steel with alloying elements such as Ni,Cr,Mo.After heat-treatment the roll shell get a fine temper structure, which exhibits good strength and ductility combined with high fatigue properties. When used, the roll shows a high wear and spalling resistance all the time.
