A work roll is a core part of a rolling mill that enters into direct contact with rolling material to make cold rolled carbon sheets (CR) of the desired thickness. Doosan Heavy Industries Construction provides high quality work rolls of uniform surface hardness in terms of surface and depth, in order to meet the diverse needs of customers.
Work roll chrome plating is a process of electrodepositing a specified thickness of chromium onto the surface of a work roll. The unique properties of chromium – high hardness, high lubricity, wear resistance and a low coefficient of friction – make chrome plating an excellent and economical choice for steel and aluminum manufacturers.
