19世紀(jì)下半葉歐洲煉鋼技術(shù)的進(jìn)步要求軋制更大噸位的鋼錠，無(wú)論是灰鑄鐵或冷硬鑄鐵軋輥的強(qiáng)度均已不能滿足要求。含碳量為0.4%～0.6%普通鑄鋼軋輥相應(yīng)誕生。重型鍛壓設(shè)備的出現(xiàn)更使這種成分的鍛造軋輥的強(qiáng)韌性得到進(jìn)一步提高。

In the second half of the nineteenth Century, the progress of steelmaking technology in Europe requires larger tonnage steel ingots to be rolled. Neither the strength of gray iron or chilled cast iron rolls can meet the requirements. The ordinary cast steel roll with a carbon content of 0.4% to 0.6% is born accordingly. The emergence of heavy forging equipment makes the strength and toughness of the forging roll of this component further improved.

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.

軋輥是軋機(jī)的核心部件，軋輥的使用涉及軋機(jī)使用時(shí)的類型選擇、軋輥的準(zhǔn)備、在軋制過(guò)程中的維修和周期性修整，而這些都全是影響軋機(jī)生產(chǎn)率、產(chǎn)品質(zhì)量和生產(chǎn)經(jīng)濟(jì)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.
