轧辊在制作和运用前的预备工序中会发生剩余应力和热应力。运用时又进一步遭到了各种周期应力的效果，包含有曲折、改变、剪力、接触应力和热应力等。
Residual stresses and thermal stresses will occur in the preparatory process before making and applying rolls. When applied， it is further affected by various cyclic stresses， including twists， changes， shear forces， contact stresses and thermal stresses.
（1）堆焊前需先将轧辊辊身表面的疲劳层或缺陷，轧辊设备生产，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， the fatigue layer or defect of the roller body surface must be first removed，轧辊报价， especially the crack must be thoroughly removed.
(2) in the process of surfacing， 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，圣霖国际轧辊， roughing roll， finishing roll; (3) according to the function of a roller descaling Kong Gun， wearing roller， flat roll etc.
