轧辊设备哪家好-轧辊-圣霖国际【顾客至上】

轧辊的分类方法有多种，主要有：（1）按产品类型分有带钢轧辊、型钢轧辊、线材轧辊等；（2）按轧辊在轧机系列中的位置分有开坯辊、粗轧辊、精轧辊等；（3）按轧辊功能分有*鳞辊、穿孔辊、平整辊等。

There are many classification methods like roller are: (1) according to the type of product with strip roller， steel roller， wire roller; (2) according to the roll in rolling mill series in the of divided blooming rolls， roughing roll， finishing roll; (3) according to the function of a roller descaling Kong Gun， wearing roller，轧辊厂家， flat roll etc.

（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，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，轧辊设备哪家好， the fatigue layer or defect of the roller body surface must be first removed， especially the crack must be thoroughly removed.

(2) in the process of surfacing，轧辊报价， in order to prevent cracks，轧辊， the roller body must be pre heated， and the preheating temperature should be determined according to roll rolls and surfacing materials.

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.
