軋輥是軋機(jī)的重要部件，按照軋機(jī)類型可分為領(lǐng)帶軋機(jī)軋輥、型鋼輪機(jī)扎輥和鋼管軋機(jī)軋輥三大類。

板帶軋機(jī)軋輥的輥身呈圓柱形，熱乾板帶軋輥的輥身微凹，當(dāng)受熱膨脹時(shí)，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.

實(shí)踐表明，帶雙鍍槽的軸頭在使用過程中，鑲槽壁容易崩裂，目前常用易加工的帶平臺(tái)的袖頭代替雙因槽的抽頭。

直徑超過400mm的冷軋軋輥，在鍛造后，多半在中心饅一個(gè)670一250mm的通7L。這樣，一力面可以使軋輥經(jīng)熱處理店的內(nèi)應(yīng)力分朽均勾；另一方面在軋輥表面淬火時(shí)，可對(duì)軋輥通水冷卻，提高淬火效果。

Practice shows that, with double bath head is in use, insert groove wall is easy to crack, at present common processing platform with the cuff instead of double slot for tap.

Cold roll diameter of more than 400mm, after forging, mostly in the 7L center. A 670 250mm. So, on one hand can make the roller stress heat treatment shop allocation hook are; on the other hand, the roll surface quenching, the water cooling roller, improve the quenching effect.

焊接時(shí)堆焊成敗的關(guān)鍵環(huán)節(jié)，要獲得理想的堆焊層必須綜合考慮某些可變因素，如：焊接電壓、焊接速度、軋輥轉(zhuǎn)速、軋輥的保溫、焊接電流、焊接材料等，對(duì)一些含碳及合金元素高的輥芯，為防止脆性區(qū)的裂紋，除一定的預(yù)熱措施外，多采用低碳低合金過渡層進(jìn)行預(yù)先堆焊過渡層。Accordingtotherolledsteelstatus,therearehotrollersandcoldrollers。  

In order to obtain an ideal surfacing layer, some variable factors must be cidered, such as welding voltage, welding speed, roll speed, roll insulation, welding current, welding material and so on. Some roll cores with high carbon and alloy elements, in order to prevent cracks in brittle zone, have to be cidered in order to obtain ideal surfacing layer. In addition, the low carbon low alloy transition layer is used to pre weld the transition layer.

軋機(jī)布置和道次設(shè)計(jì)  

機(jī)架在生產(chǎn)線的位置以及道次設(shè)計(jì)對(duì)軋輥的選擇有很大影響。根據(jù)機(jī)架位置，軋輥的受力方式和性能可以有很大變化。這是因?yàn)閼?yīng)用于粗軋機(jī)架和精軋機(jī)架的軋輥有非常不同的受力方式，從而導(dǎo)致軋輥性能有預(yù)期的改變.

Rolling mill layout and pass design

The of the rack in the production line and the design of the pass have great influence on the choice of the roll. According to the  of the frame, the force and performance of the roller can be greatly changed. This ibecause the rolls used in roughing mill stand and finishing mill stand have very different forces, resulting in expected changes in roll performance.
