圣霖国际轧辊询问报价

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.).

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