軋機上使金屬產(chǎn)生連續(xù)塑性變形的主要工作部件和工具。軋輥主要由輥身、輥頸和軸頭3部分組成。

輥身是實際參與軋制金屬的軋輥中間部分。它具有光滑的圓柱形或帶軋槽的表面。輥頸安裝在軸承中,并通過軸承座和壓下裝置把軋制力傳給機架。



The roller body is the middle part of the roll that actually takes part in rolling the metal. It has a smooth cylinder or a surface with a groove. The roller neck is installed in the bearing and passes the rolling force to the rack through the bearing seat and the press down device. .


這些應(yīng)力沿輥身的散布是不均勻的、不斷改變的,其原因不只有規(guī)劃要素,還有軋輥在運用中磨損、溫度和輥形的不斷改變。

The dispersion of these stresses along the roll is uneven and ctantly changing, and the reas are not only the planning elements, but also the ctant change of wear, temperature and roll shape in the use of the rolls.


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.
