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.
轧辊中大量使用合金元素是在第二次以后，吊车轨生产厂家，这是轧钢设备朝着大型化、连续化、高速化、自动化发展以及轧材强度提高、变形抗力加大后对轧辊性能提出更高要求的结果。
A large number of alloying elements in the rolls are produced after the Second World War.the result of rolling mill"s large performance， continuous， high-speed and automatic development， as well as the increase of rolling strength and resistance to deformation.
轧辊在轧机中的使用效果不但取决于轧辊材质及其冶金质量，吊车轨价格，还和使用条件、轧辊设计、操作维护有关。不同类型轧机的轧辊使用条件有很大差异，造成差异的因素有：轧机条件。如轧机类型、轧机和轧辊设计、孔型设计、水冷条件和轴承种类等。
The use effect of roll in the rolling mill not only depends on the material and metallurgical quality of the roll，吊车轨生产商， but also is related to the conditi of use，吊车轨， the design of the roll and the operation and maintenance. The use conditi of the rolls for different types of rolling mills are very different. The factors that cause the difference are the rolling mill conditi. Such as rolling mill type， rolling mill and roll design， pass design， water cooling condition and bearing type and so on.
