Cold roll manufacturing process can be divided into three stages: the first stage is 1940-1960, when forged steel rolls were mostly used as cold rolls, smelted in electric arc furnace without vacuum d

The development of cold rolling rolls is driven by the pull of the cold rolling industry and the related technology of roll manufacturing.

The cold roll is a complex component with a very hard surface, which bears a great deal of stress. Therefore, the cold roll requires a high manufacturing quality, which is the necessary condition to e
