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.

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。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。  

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.

在粗軋機(jī)架后，中型型材軋機(jī)有兩組連續(xù)的機(jī)架。連續(xù)軋機(jī)，根據(jù)孔型設(shè)計(jì)既可以水平布置，也可以立式布置。對(duì)于有平行緣的型鋼和槽鋼，還配有機(jī)架。

After the roughing mill, there are two sets of continuous rack in the medium section mill. The continuous rolling mill can be arranged horizontally or vertically according to the pass design. For steel and channel steel with parallel edges, universal frame is also available.
