sleeper厂-sleeper-圣霖国际【精益求精】

由于轧制过程是连续的过程，因此操作人员需要不断检测轧辊状况，使生产出来的产品满足用户对更严格的公差和表面质量的要求。

As the rolling process is a continuous process， the operator needs to continuously detect the roll status to meet the more stringent tolerance and surface quality requirements of the products produced.

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，sleeper谁家好， 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，sleeper， etc.).

不同类型的轧机以及同类型而使用条件不同的轧机，对所用的轧辊性能要求不尽雷同，sleeper厂，如方坯和板坯初轧机轧辊要具有好的扭转和弯曲强度、韧性、咬入性、抗热裂性和热冲击性以及耐磨性；而热带精轧机架要求轧辊辊面的高硬度、抗压痕、耐磨、抗剥落和耐热裂等性能。

Different types of rolling mill and the same type and the use of different conditi on properties of roll mill， requirements for not identical，sleeper哪家好， such as billet and slab mill roll with good torsional and bending strength， toughness， bite， thermal cracking resistance and thermal shock resistance and abrasion resistance; tropical finishing stand requirements the roller surface hardness， wear resistance， spalling resistance， indentation resistance and thermal cracking performance.
