軋輥是軋機的重要部件，按照軋機類型可分為領(lǐng)帶軋機軋輥、型鋼輪機扎輥和鋼管軋機軋輥三大類。

板帶軋機軋輥的輥身呈圓柱形，熱乾板帶軋輥的輥身微凹，當受熱膨脹時，可保持較好的扳形。

Roll is an important part of the rolling mill. According to the type of rolling mill, it can be divided into three types: the tie mill roll, the type steel turbine ligation roll and the steel tube rolling mill roll.

The roll body of a strip rolling mill is cylindrical, and the roll body of the hot dry plate is slightly concave. When the heat is expanded, it can maintain a better shape.

冷軋輥在工作過程中要承受很大的軋制應(yīng)力，加上軋件的焊縫、夾雜、邊裂等問題，容易導(dǎo)致瞬間高溫，使工作輥受到強烈熱沖擊，造成裂紋、粘輥、剝落甚至報廢。因此，冷軋輥要有抵抗因彎曲應(yīng)力、扭轉(zhuǎn)應(yīng)力、剪切應(yīng)力引起的開裂和剝落的能力，同時也要有高的耐磨性。軋機布置和道次設(shè)計機架在生產(chǎn)線的位置以及道次設(shè)計對軋輥的選擇有很大影響。

Cold roll must bear a lot of rolling stress in the working process, add the weld, inclusion and edge crack of the rolled piece, which can easily lead to instantaneous high temperature, so that the work roll is subjected to strong heat shock, which causes crack, roll, peeling and even scrap. Therefore, the cold roller must resist the ability of cracking and spalling caused by bending stress, torsional stress and shearing stress, and also has high wear resistance.

整體軋輥是相對于復(fù)合軋輥而言的，整體軋輥的輥身外層與心部以及輥頸采用單一材質(zhì)鑄造或鍛造而成，輥身外層和輥頸不同的組織、性能通過鑄造或鍛造工藝以及熱處理工藝過程來控制和調(diào)整。

The whole roll is compared to the  roll. The outer layer of the whole roll is made of a single material or forging with a single material. The structure and performance of the roll are  and adjusted by the casting or forging process and the heat treatment process.

生產(chǎn)長材產(chǎn)品的軋機種類繁多，因此，軋機類型的選擇、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，不同的軋機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.
