说明

由于外层离心浇注,辊身组织冷硬层中存在细小且弥散的石墨,石墨量由表及里缓慢而均匀增多,使得冷硬深度无明显界线。轧辊硬度降落小并且抗热裂性好。同时中心经过单独球化处理,强度较高。具有较高的耐磨损性能和抗裂纹、抗剥落性、抗印痕能力。确保成品板材的表面质量和尺寸精度。

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.
