硬質合金軋輥是在硬質合金刀具的基礎上發(fā)展而來的，硬質合金是采用堅硬的碳化鎢顆粒硬質相與鎳、鈷等黏結相金屬燒結而成。硬質合金的性能取決于碳化鎢顆粒尺寸的大小和黏結相金屬含量的多少，當黏結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。這些應力沿輥身的散布是不均勻的、不斷改變的，其原因不只有規(guī)劃要素，還有軋輥在運用中磨損、溫度和輥形的不斷改變。

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.

而精軋輥速度較高，軋制終產(chǎn)品要有一定的表面質量，對它以硬度、耐磨等為主要要求。然后考慮軋輥使用時所應有的耐磨性。由于軋輥的磨損機理很復雜，包括機械應力作用、軋制時的熱作用、冷卻作用、潤滑介質的化學作用以及其他作用。

And the high speed of the fine roller, the final product of rolling must have a certain surface quality, which is the main requirement for its hardness, wear resistance and so on. Then the wear resistance should be cidered when the roll is used. Because the wear mechanism of roller is very complicated, including mechanical stress, thermal action during rolling, cooling effect, chemical action of lubricating medium and other functi.

既避免機械加工，又無補焊熱應力熱影響，修正厚度也不受捆綁，一起產(chǎn)品所具有的耐磨性及金屬材料不具備的退讓性，確保修正部位的接觸協(xié)作。

Not only to avoid mechanical processing, but also to weld hot stress and heat, the correction thickness is not bound, and the wear resistance of a product and the non - concession of metal materials are not available, so as to ensure a hundred percent contact and cooperation of the corrected parts.

初軋機、鋼坯連軋機、大型型鋼和軌梁軋機、熱軋板帶鋼軋機破鱗和軋邊機、型鋼軋機的軋邊機，還有小型型鋼、線棒材軋機的粗軋機架等軋機使用的軋輥，大多采用整體鑄造方法生產(chǎn)，這類軋輥使用層較厚，孔型較深。

The rolling mill of rolling mill, billet rolling mill, large type steel and rail beam mill, hot rolled strip mill break scale, rolling edge mill, type steel universal mill, and rolling mill used in small steel and wire rod mill are mostly produced by the whole casting method, which is thicker and deeper.
