軋輥是軋機的重要部件，按照軋機類型可分為領帶軋機軋輥、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.

硬質合金輥環(huán)廣泛應用于高速線材軋機的精軋機架，以及部分高速線材軋機的預精軋機架和棒材軋機的精軋機架。硬質合金軋輥的優(yōu)點是硬度高、耐磨性好，單槽軋鋼量可以達到高速鋼軋輥的兩倍。

The cemented carbide roller ring is widely applied to the finishing mill housing of high-speed wire rod mill, as well as the finishing mill for some high speed wire rod mill and the pre finishing mill and bar mill. The biggest advantage of the hard alloy roll is high hardness and good wear resistance, and the amount of single groove rolled steel can reach two times of the high speed steel roll.

而精軋輥速度較高，軋制終產(chǎn)品要有一定的表面質量，對它以硬度、耐磨等為主要要求。然后考慮軋輥使用時所應有的耐磨性。由于軋輥的磨損機理很復雜，包括機械應力作用、軋制時的熱作用、冷卻作用、潤滑介質的化學作用以及其他作用。

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.

軋輥是軋機的核心部件，軋輥的使用涉及軋機使用時的類型選擇、軋輥的準備、在軋制過程中的維修和周期性修整，而這些都全是影響軋機生產(chǎn)率、產(chǎn)品質量和生產(chǎn)經(jīng)濟性的因素。

Roll is the core part of the rolling mill. The use of the roll involves the type selection of the rolling mill, the preparation of the roll, the maintenance and the periodic dressing during the rolling process, all of which are all factors that affect the productivity of the rolling mill, the quality of the product and the production economy.
