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,轧辊, the roll body is usually divided into the surface area, the center area and the middle area according to the force condition,轧辊采购, and then the critical dimensions 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世界大战以后,轧辊设备哪家好,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.
