硬质合金辊环广泛应用于高速线材轧机的精轧机架，以及部分高速线材轧机的预精轧机架和棒材轧机的精轧机架。硬质合金轧辊的优点是硬度高、*性好，轧辊设备哪家好，单槽轧钢量可以达到高速钢轧辊的两倍。

The cemented carbide roller ring is widely applied to the finishing mill housing of high-speed wire rod mill，大庆轧辊， as well as the finishing mill for some high speed wire rod mill and the pre finishing mill and bar mill. The bi*est advantage of the hard alloy roll is high hardness and good wear resistance， and the amou*f single groove rolled steel can reach two times of the high speed steel roll.

轧辊的品种和制造工艺随冶金技术的进步和轧钢设备的演变而不断发展。中世纪轧制软的有色金属时使用强度低的灰铸铁轧辊。18世纪中叶英国掌握了轧制钢板用的冷硬铸铁轧辊的生产技术。

The variety and manufacturing process of roll h*e 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 nonferrou*etals. In the middle of the eighteenth Century， Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.
