軋輥在軋機中的使用效果不但取決于軋輥材質及其冶金質量，還和使用條件、軋輥設計、操作維護有關。不同類型軋機的軋輥使用條件有很大差異，造成差異的因素有：軋機條件。如軋機類型、軋機和軋輥設計、孔型設計、水冷條件和軸承種類等。

The use effect of roll in the rolling mill not only depends on the material and metallurgical quality of the roll, but also is related to the conditi of use, the design of the roll and the operation and maintenance. The use conditi of the rolls for different types of rolling mills are very different. The factors that cause the difference are the rolling mill conditi. Such as rolling mill type, rolling mill and roll design, pass design, water cooling condition and bearing type and so on.

冷軋輥在工作過程中要承受很大的軋制應力，加上軋件的焊縫、夾雜、邊裂等問題，容易導致瞬間高溫，使工作輥受到強烈熱沖擊，造成裂紋、粘輥、剝落甚至報廢。Rollisanimportantpartoftherollingmill。因此，冷軋輥要有抵抗因彎曲應力、扭轉應力、剪切應力引起的開裂和剝落的能力，同時也要有高的耐磨性。

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.

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.

（1）堆焊前需先將軋輥輥身表面的疲勞層或缺陷，尤其是裂紋必須徹底清除；  

（2）在堆焊時，為了防止裂紋的產(chǎn)生，必須先加工軋輥輥身預熱，預熱溫度根據(jù)軋輥輥及堆焊材料而定。

(1) before welding, the fatigue layer or defect of the roller body surface must be first removed, especially the crack must be thoroughly removed.

(2) in the process of surfacing, in order to prevent cracks, the roller body must be pre heated, and the preheating temperature should be determined according to roll rolls and surfacing materials.
