冷轧板带轧辊的辊身呈微凸，当它受力弯曲时可保证良好扳形；型钢轧机轧辊的辊身上有轧槽，根据型钢轧制工艺要求，安排孔型。钢管轧制中采用斜轧原理轧制的轧辊有圆锥形、腰鼓形或盘形。Therollbodyofthecoldrolledstriprollerisslightlyconvex.Whenitisbentbyforce,itcanensuregoodshape.Therearegroovesontherollerbodyofthesectionmillroll,andthepassisarrangedaccordingtotherollingrequirementsofsectionsteel.Therollersofskewrollingrollingrollingprincipleofconicaldrumordisc.弄清轧辊的使用条件以及在同类型轧机中所用轧辊的失效方式，了解当前各种轧辊材质的性能和制造工艺，才能较正确地制定该轧机用辊的技术条件和选用合适而经济的轧辊材质。Wemustknowclearlytheconditionoftherollerandthefailurewayoftherollusedinthesametypeofrollingmill,andunderstandtheperformanceandmanufacturingtechnologyofallkindsofrollermaterialatpresent,sothatwecancorrectlyformulatethetechnicalconditioftherollerandchoosetherightandeconomicalrollermaterial.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。Nondestructivetestingofrollsisusuallycarriedoutbyultrasonicflawdetectors.Inthetestingstandardofcoldroll,therollbodyisusuallydividedintothesurfacearea,thecenterareaandthemiddleareaaccordingtotheforcecondition,andthenthecriticaldimensiofthedefectsareallowedineachareaaccordingtotheprincipleoffracturemechanics.)
