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.


軋機(jī)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(shí)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(guò)軸承座和壓下裝置把軋制力傳給機(jī)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. .


軋輥在制作和運(yùn)用前的預(yù)備工序中會(huì)發(fā)生剩余應(yīng)力和熱應(yīng)力。運(yùn)用時(shí)又進(jìn)一步遭到了各種周期應(yīng)力的效果,包含有曲折、改變、剪力、接觸應(yīng)力和熱應(yīng)力等。

Residual stresses and thermal stresses will occur in the preparatory process before making and applying rolls. When applied, it is further affected by various cyclic stresses, including twists, changes, shear forces, contact stresses and thermal stresses.


當(dāng)軋制其它型材時(shí),可以用水平機(jī)架更換機(jī)架。水平機(jī)架的軋輥有很深的孔型,而機(jī)架沒有。  

較大直徑的水平軋輥確定型鋼的的形狀,而較小直徑的一對(duì)立輥用于軋制邊部。當(dāng)坯料穿過(guò)傳統(tǒng)機(jī)架和機(jī)架精軋軋輥時(shí),可以獲得很好的表面光潔度和尺寸公差。  


When rolling other profiles, the universal rack can be replaced with a horizontal rack. The roll of the horizontal frame has a very deep pass, but the universal rack does not.


Horizontal rolls with larger diameters determine the shape of the section steel, and a pair of rolls with smaller diameters are used for rolling edges. Good surface finish and dimensional tolerance can be obtained when the blank passes through the conventional stand and universal stand finish rolls.
