crane rail哪家好-圣霖国际【开拓创新】

这些应力沿辊身的散布是不均匀的、不断改变的，其原因不只有规划要素，还有轧辊在运用中磨损、温度和辊形的不断改变。

The dispersion of these stresses along the roll is uneven and ctantly changing， and the reas are not only the planning elements， but also the ctant change of wear， temperature and roll shape in the use of the rolls.

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 usually carried out by ultrasonic flaw detectors. In the testing standard of cold roll， the roll body is usually divided into the surface area， the center area and the middle area according to the force condition， and then the critical dimensi of the defects are allowed in each area according to the principle of fracture mechanics.

修正精度高，涂层厚度从几微米到几毫米，crane rail，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 the coating is from several micr*** to a few millimeters. It can be worn，crane rail哪家好， scratched，crane rail生产商， pinholes， cracks， breakage and deformation， hardness reduction， damage and other shortcomings to accumulate， seal， and compensate for the defects，crane rail价格， such as grinding， polishing， milling， milling， grinding and other kinds of mechanical processing， as well as electroplating later processing.
