硬質(zhì)合金軋輥是在硬質(zhì)合金刀具的基礎(chǔ)上發(fā)展而來的，硬質(zhì)合金是采用堅(jiān)硬的碳化鎢顆粒硬質(zhì)相與鎳、鈷等黏結(jié)相金屬燒結(jié)而成。硬質(zhì)合金的性能取決于碳化鎢顆粒尺寸的大小和黏結(jié)相金屬含量的多少，當(dāng)黏結(jié)相金屬中含有一定量的鎳和鉻時，不僅會大大提高軋輥的抗熱疲勞性能。硬質(zhì)合金軋輥的優(yōu)點(diǎn)是硬度高、耐磨性好，單槽軋鋼量可以達(dá)到高速鋼軋輥的兩倍。

Cemented carbide rolls are developed on the basis of cemented carbide tools. Cemented carbide is made of hard tungsten carbide particles and hard phase sintered together with nickel and cobalt bonded phases. The properties of cemented carbide depend on the size of tungsten carbide particle and the content of bonding phase metal. When the amount of nickel and chromium in the bonding phase contains metal, it will not only greatly improve the thermal fatigue resistance of the roller.

軋輥的品種和制造工藝隨冶金技術(shù)的進(jìn)步和軋鋼設(shè)備的演變而不斷發(fā)展。中世紀(jì)軋制軟的有色金屬時使用強(qiáng)度低的灰鑄鐵軋輥。18世紀(jì)中葉英國掌握了軋制鋼板用的冷硬鑄鐵軋輥的生產(chǎn)技術(shù)。

The variety and manufacturing process of roll have been developed with the progress of metallurgical technology and the evolution of steel rolling equipment. The use of low strength gray iron rolls in the Middle Ages when rolling soft nonferrous metals. In the middle of the eighteenth Century, Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.

整體軋輥是相對于復(fù)合軋輥而言的，整體軋輥的輥身外層與心部以及輥頸采用單一材質(zhì)鑄造或鍛造而成，輥身外層和輥頸不同的組織、性能通過鑄造或鍛造工藝以及熱處理工藝過程來控制和調(diào)整。

The whole roll is compared to the  roll. The outer layer of the whole roll is made of a single material or forging with a single material. The structure and performance of the roll are  and adjusted by the casting or forging process and the heat treatment process.
