sleeper厂服务介绍

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.).

而精轧辊速度较高，轧制终产品要有一定的表面质量，对它以硬度、耐磨等为主要要求。然后考虑轧辊使用时所应有的耐磨性。由于轧辊的磨损机理很复杂，包括机械应力作用、轧制时的热作用、冷却作用、润滑介质的化学作用以及其他作用。

And the high speed of the fine roller, the final product of rolling must h***e a certain surface quality, which is the main requirement for its hardness, wear resistance and so on. Then the wear resistance should be cidered when the roll is used. Because the wear mechani*** of roller is very complicated, including mechanical stress, thermal action during rolling, cooling effect, chemical action of lubricating medium and other functi.

既避免机械加工，又无补焊热应力热影响，修正厚度也不受***，一起产品所具有的耐磨性及金属材料不具备的退让性，确保修正部位的接触协作。

Not only to ***oid mechanical processing, but also to weld hot stress and heat, the correction thickness is not bound, and the wear resistance of a product and the non - concession of metal materials are not ***ailable, so as to ensure a hundred percent contact and cooperation of the corrected parts.

什么是铸造轧辊，铸造轧辊主要有哪些种类？

铸造轧辊是指将冶炼钢水或熔炼铁水直接浇注成型这一生产方式制造的轧辊种类。

铸造轧辊按材质又可分为铸钢轧辊和铸铁轧辊两类；按制造方法又可分为整体铸造轧辊和复合铸造轧辊两类。

What are the casting rolls and what are the main types of casting rolls?

The casting roller refers to the type of rolls produced by direct casting of molten steel or molten iron.

The casting roll can be divided into two types: cast steel roll and cast iron roll according to material quality. According to the manufacturing method, it can also be divided into two types: integral casting roll and compound casting roll.
