Description

As the outer layer centrifugal casting, body chilled layer exists in small and dispersion graphite. The graphite increased slowly and evenly from surface to the inner, so that the chilled depth has no significant line. That roll hardness drop little and has good resistance to thermal cracking. At the same time the center has a higher intensity by separate nodulizing. With a high wear-resistant properties and anti-crack, anti-peeling, anti-prints capacity. These types of roll ensure that the plats surface quality and dimensional accuracy.
