軋輥的分類方法有多種，主要有：（1）按產(chǎn)品類型分有帶鋼軋輥、型鋼軋輥、線材軋輥等；（2）按軋輥在軋機(jī)系列中的位置分有開坯輥、粗軋輥、精軋輥等；（3）按軋輥功能分有破鱗輥、穿孔輥、平整輥等。

There are many classification methods like roller are: (1) according to the type of product with strip roller, steel roller, wire roller; (2) according to the roll in rolling mill series in the of divided blooming rolls, roughing roll, finishing roll; (3) according to the function of a roller descaling Kong Gun, wearing roller, flat roll etc.

而精軋輥速度較高，軋制終產(chǎn)品要有一定的表面質(zhì)量，對(duì)它以硬度、耐磨等為主要要求。然后考慮軋輥使用時(shí)所應(yīng)有的耐磨性。由于軋輥的磨損機(jī)理很復(fù)雜，包括機(jī)械應(yīng)力作用、軋制時(shí)的熱作用、冷卻作用、潤(rùn)滑介質(zhì)的化學(xué)作用以及其他作用。

And the high speed of the fine roller, the final product of rolling must have a certain surface quality, which is the main requirement for its hardness, wear resistance and so on. Then the wear resistance should be cidered when the roll is used. Because the wear mechanism of roller is very complicated, including mechanical stress, thermal action during rolling, cooling effect, chemical action of lubricating medium and other functi.

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(yùn)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.

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.
