軋輥中大量使用合金元素是在第二次以后，這是軋鋼設(shè)備朝著大型化、連續(xù)化、高速化、自動(dòng)化發(fā)展以及軋材強(qiáng)度提高、變形抗力加大后對(duì)軋輥性能提出更高要求的結(jié)果。

A large number of alloying elements in the rolls are produced after the Second World War.the result of rolling mill's large performance, continuous, high-speed and automatic development, as well as the increase of rolling strength and resistance to deformation.

軋輥的分類(lèi)方法有多種，主要有：（1）按產(chǎn)品類(lèi)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(kāi)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.

線材軋機(jī)擁有粗軋機(jī)架和與小型型材軋機(jī)類(lèi)似的中間機(jī)架。與兩線軋制的小型型材軋機(jī)相比，這些軋機(jī)一般被設(shè)計(jì)成可以進(jìn)行高達(dá)4線的同時(shí)軋制的切分軋制。然而，目前的發(fā)展趨勢(shì)是采用單線的高速軋制。

The wire mill has a roughing mill stand and an intermediate rack similar to a small section mill. Compared with the two section rolling mill, these mills are generally designed for rolling up to 4 lines at the same time. However, the current development trend is single line high-speed rolling.
