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，轧辊设备， but also the ctant change of wear， temperature and roll shape in the use of the rolls.
轧辊中大量使用合金元素是在第二次以后，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.
（1）堆焊前需先将轧辊辊身表面的疲劳层或缺陷，轧辊生产商，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，轧辊设备生产厂家，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， the fatigue layer or defect of the roller body surface must be first removed，轧辊， especially the crack must be thoroughly removed.
(2) in the process of surfacing， in order to prevent cracks， the roller body must be pre heated， and the preheating temperature should be determined according to roll rolls and surfacing materials.
