常用的轧辊材质和用途见表。轧辊的性能和质量一般取决于其化学成分和制造方式并可由其组织、物理和力学性能以及存在于轧辊内部的残余应力类型来评估(见轧辊检验)。
The material and use of the commonly used rolls are shown in the table. The performance and quality of roller generally depend on its chemical and manufacturing way, and can be evaluated by its organization, physical and mechanical properties and the type of residual stress existing inside the roll (see roll test).
修正精度高,涂层厚度从几微米到几毫米,可对金属工件呈现磨损、划伤、、裂纹、破损变形、硬度降低、损害等缺点进行堆积、封孔、补对等修正功用,轧辊生产厂家,只须打磨、抛光,也可进行车、铣、 刨、磨等各类机械加工,以及电镀等后期加工。
The thickness of the coating is high, and the thickness of the coating is from several microns to a few millimeters. It can be worn, scratched, pinholes, cracks, breakage and deformation,轧辊厂家, hardness reduction,轧辊设备, damage and other shortcomings to accumulate, seal, and compensate for the defects, such as grinding, polishing, milling, milling, grinding and other kinds of mechanical processing, as well as electroplating later processing.
实践表明,带双镀槽的轴头在使用过程中,镶槽壁容易崩裂,目前常用易加工的带平台的袖头代替双因槽的抽头。
直径超过400mm的冷轧轧辊,在锻造后,多半在中心馒一个670一250mm的通7L。这样,一力面可以使轧辊经热处理店的内应力分朽均勾;另一方面在轧辊表面淬火时,可对轧辊通水冷却,提高淬火效果。
Practice shows that, with double bath head is in use,轧辊, insert groove wall is easy to crack, at present common processing platform with the cuff instead of double slot for tap.
Cold roll diameter of more than 400mm, after forging, mostly in the 7L center. A 670 250mm. So, on one hand can make the roller stress heat treatment shop allocation hook are; on the other hand, the roll surface quenching, the water cooling roller, improve the quenching effect.
