冷軋板帶軋輥的輥身呈微凸，當它受力彎曲時可保證良好扳形；型鋼軋機軋輥的輥身上有軋槽，根據型鋼軋制工藝要求，安排孔型。鋼管軋制中采用斜軋原理軋制的軋輥有圓錐形、腰鼓形或盤形。

The roll body of the cold rolled strip roller is slightly convex. When it is bent by force, it can ensure good shape. There are grooves on the roller body of the section mill roll, and the pass is arranged according to the rolling requirements of section steel. The rollers of skew rolling rolling rolling principle of conical drum or disc.

軋輥中大量使用合金元素是在第二次以后，這是軋鋼設備朝著大型化、連續化、高速化、自動化發展以及軋材強度提高、變形抗力加大后對軋輥性能提出更高要求的結果。

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.

修正精度高，涂層厚度從幾微米到幾毫米，可對金屬工件呈現磨損、劃傷、、裂紋、破損變形、硬度降低、損害等缺點進行堆積、封孔、補對等修正功用，只須打磨、拋光，也可進行車、銑、 刨、磨等各類機械加工，以及電鍍等后期加工。

The thickness of the coating is high, and the thickness of the coating is from several microns to a few millimeters. It can be worn, scratched, pinholes, cracks, breakage and deformation, hardness reduction, damage and other shortcomings to accumulate, seal, and compensate for the defects, such as grinding, polishing, milling, milling, grinding and other kinds of mechanical processing, as well as electroplating later processing.

軋輥的無損檢測通常用超聲波探傷儀進行。冷軋輥探傷標準中通常把輥身依受力情況分成表面區、中心區和中間區，然后依斷裂力學原理分別規定各區允許存在的缺陷的臨界尺寸。

Nondestructive testing of rolls is usually carried out by ultrasonic flaw detectors. In the testing standard of cold roll, the roll body is usually divided into the surface area, the center area and the middle area according to the force condition, and then the critical dimensi of the defects are allowed in each area according to the principle of fracture mechanics.
