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、针孔、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，轧辊设备生产厂家， and the thicknessof the coating is from several microns to a few millimeters. It canbe worn， scratched， pinholes， cracks， breakage and deformation，hardness reduction， damage and other shortcomings toaccumulate，轧辊采购， seal， and compensate for the defects，轧辊， such asgrinding， polishing， milling， milling， grinding and other kinds ofmechanical processing， as well as electroplating laterprocessing.
轧机上使金属产生连续塑性变形的主要工作部件和工具。轧辊主要由辊身、辊颈和轴头3部分组成。
辊身是实际参与轧制金属的轧辊中间部分。它具有光滑的圆柱形或带轧槽的表面。辊颈安装在轴承中，并通过轴承座和压下装置把轧制力传给机架。
Theroller body is the middle part of the roll that actually takes partin rolling the metal. It has a smooth cylinder or a surface with agroove. The roller neck is installed in the bearing and passes therolling force to the rack through the bearing seat and the pressdown device. .
轧辊的无损检测通常用超声波探伤仪进行。冷轧辊探伤标准中通常把辊身依受力情况分成表面区、中心区和中间区，然后依断裂力学原理分别规定各区允许存在的缺陷的临界尺寸。
Nondestructive testing of rolls is usuallycarried out by ultrasonic flaw detectors. In the testing standardof cold roll， the roll body is usually divided into the surfacearea， the center area and the middle area according to the forcecondition， and then the critical dimensions of the defects areallowed in each area according to the principle of fracturemechanics.
