初轧机、钢坯连轧机、大型型钢和轨梁轧机、热轧板带钢轧机破鳞和轧边机、型钢轧机的轧边机，还有小型型钢、线棒材轧机的粗轧机架等轧机使用的轧辊，crane rail报价，大多采用整体铸造方法生产，这类轧辊使用层较厚，孔型较深。

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，crane rail生产厂家， and rolling mill used in ***all steel and wire rod mill are mostly produced by the whole casting method， which is thicker and deeper.

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，crane rail， and can be evaluated by its organization， physical and mechanical properties and the type of residual stress existing inside the roll (see roll test).
