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、耐磨性好，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， as well as the finishing mill for some high speed wire rod mill and the pre finishing mill and bar mill. The biggest advantage of the hard alloy roll is high hardness and good wear resistance，sleeper哪家好， and the amount of single groove rolled steel can reach two times of the high speed steel roll.

轧辊在轧机中的使用效果不但取决于轧辊材质及其冶金质量，还和使用条件、轧辊设计、操作维护有关。不同类型轧机的轧辊使用条件有很大差异，造成差异的因素有：轧机条件。如轧机类型、轧机和轧辊设计、孔型设计、水冷条件和轴承种类等。

The use effect of roll in the rolling mill not only depends on the material and metallurgical of the roll， but also is related to the conditions of use， the design of the roll and the operation and maintenance. The use conditions of the rolls for different types of rolling mills are very different. The factors that cause the difference are the rolling mill conditions. Such as rolling mill type，sleeper生产厂家， rolling mill and roll design， pass design， water cooling condition and bearing type and so on.

这些应力沿辊身的散布是不均匀的、不断改变的，其原因不只有规划要素，还有轧辊在运用中磨损、温度和辊形的不断改变。

The dispersion of these stresses along the roll is uneven and constantly changing，黑龙江sleeper， and the reasons are not only the planning elements， but also the constant change of wear， temperature and roll shape in the use of the rolls.
