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.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。AlargenumberofalloyingelementsintherollsareproducedaftertheSecondWorldWar.theresultofrollingmillslargeperformance,continuous,high-speedandautomaticdevelopment,aswellastheincreaseofrollingstrengthandresistancetodeformation.线材轧机拥有粗轧机架和与小型型材轧机类似的中间机架。与两线轧制的小型型材轧机相比，这些轧机一般被设计成可以进行高达4线的同时轧制的切分轧制。然而，目前的发展趋势是采用单线的高速轧制。Thewiremillhasaroughingmillstandandanintermediateracksimilartoa***allsectionmill.Comparedwiththetwosectionrollingmill,thesemillsaregenerallydesignedforrollingupto4linesatthesametime.However,thecurrentdevelopmenttrendissinglelinehigh-speedrolling.)
