Rolls are mainly divided intothree categories: cast steel series rolls， cast iron series rollersand forging series rolls.
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，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 thecoating is from several micr to a few millimeters. It can be worn，scratched， pinholes， cracks，轧辊， breakage and deformation， hardnessreduction， damage and other shortcomings to accumulate， seal， andcompensate for the defects， such as grinding， polishing， milling，milling， grinding and other kinds of mechanical processing，轧辊设备哪家好，as well as electroplating later processing.
（1）堆焊前需先将轧辊辊身表面的疲劳层或缺陷，尤其是裂纹必须彻底清除；
（2）在堆焊时，轧辊厂家，为了防止裂纹的产生，必须先加工轧辊辊身预热，预热温度根据轧辊辊及堆焊材料而定。
(1) before welding， the fatigue layer or defect of the rollerbody surface must be first removed， especially the crack must bethoroughly removed.
(2) in the process of surfacing， in order to prevent cracks， theroller body must be pre heated， and the preheating temperatureshould be determined according to roll rolls and surfacingmaterials.
