軋輥由輥身、輥頸和軸頭二部分組成。輥頸安裝在軸承中，并通過(guò)袖承座和壓下裝置把軋制力傳給機(jī)架。鉑頭和連接軸相連接，傳遞軋制扭矩。軸頭有三種主要形式；梅花軸頭、萬(wàn)向軸頭、帶鍵槽的或圓柱形軸頭。

The roll is  of two parts of the roller body, the neck of the roll and the shaft head. The roll neck is installed in the bearing and passes through the sleeve bearing seat and the press down device to the rack. The platinum head is connected to the connecting shaft to transfer the rolling torque. There are three main forms of the shaft; the shaft of a plum, a universal shaft, or a cylindrical shaft with a keyway.

弄清軋輥的使用條件以及在同類型軋機(jī)中所用軋輥的失效方式，了解當(dāng)前各種軋輥材質(zhì)的性能和制造工藝，才能較正確地制定該軋機(jī)用輥的技術(shù)條件和選用合適而經(jīng)濟(jì)的軋輥材質(zhì)。

We must know clearly the condition of the roller and the failure way of the roll used in the same type of rolling mill, and understand the performance and manufacturing technology of all kinds of roller material at present, so that we can correctly formulate the technical conditi of the roller and choose the right and economical roller material.

修正精度高，涂層厚度從幾微米到幾毫米，可對(duì)金屬工件呈現(xiàn)磨損、劃傷、、裂紋、破損變形、硬度降低、損害等缺點(diǎn)進(jìn)行堆積、封孔、補(bǔ)對(duì)等修正功用，只須打磨、拋光，也可進(jìn)行車、銑、 刨、磨等各類機(jī)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.

生產(chǎn)長(zhǎng)材產(chǎn)品的軋機(jī)種類繁多，因此，軋機(jī)類型的選擇、布局，軋輥材質(zhì)的選擇、軋輥尺寸的確定，選擇范圍也非常廣。同時(shí)，不同的軋機(jī)所選擇的軋輥也是不相同的，需要根據(jù)生產(chǎn)要求選擇軋輥。

There are a wide variety of rolling mills to produce long timber products. Therefore, the selection and layout of the type of rolling mill, the selection of the material of the roll and the determination of the size of the roll are also very wide. At the same time, the rolls chosen by  rolling mills are also the roller should be selected according to the production requirements.
