常用的轧辊材质和用途见表。轧辊的性能和质量一般取决于其化学成分和制造方式并可由其***、物理和力学性能以及存在于轧辊内部的残余应力类型来评估（见轧辊检验）。

The material and use of the commonly used rolls are shown in the table. The performance and quality of roller generally depend on its chemical and manufacturing way, and can be evaluated by its organization, physical and mechanical properties and the type of residual stress existing inside the roll (see roll test).

通常对粗轧辊以强度、抗热裂为主要要求；小型20辊轧机的工作轧辊重仅 100克左右，而宽厚板轧机的支承辊重量已超过200吨。选用轧辊时首先根据轧机对轧辊的基本强度要求，选定安全承载的主体材料（各种级别的铸铁、铸钢或锻钢等）。

Usually, the main requirements for rough rolling roll are strength and thermal cracking. The working roll weight of ***all 20 high mill is only 100 grams, while the weight of backup roll of wide plate mill has exceeded 200 t. When selecting the roll, first, according to the requirements of the mill's basic strength for the roller, we select the main material for safety loading (various grades of cast iron, cast steel or forged steel, etc.).

生产长材产品的轧机种类繁多，因此，轧机类型的选择、布局，轧辊材质的选择、轧辊尺寸的确定，选择范围也非常广。同时，不同的轧机所选择的轧辊也是不相同的，需要根据生产要求选择轧辊。

There are a wide variety of rolling mills to produce long timber products. Therefore, the selection and layout of the type of rolling mill, the selection of the material of the roll and the determination of the size of the roll are also very wide. At the same time, the rolls chosen by rolling mills are also the roller should be selected according to the production requirements.
