sleeper哪家好-圣霖国际(推荐商家)

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).

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哪家好，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， 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，沈阳sleeper， spalling resistance， indentation resistance and thermal cracking performance.

实践表明，带双镀槽的轴头在使用过程中，镶槽壁容易崩裂，目前常用易加工的带平台的袖头代替双因槽的抽头。

直径超过400mm的冷轧轧辊，在锻造后，多半在中心馒一个670一250mm的通7L。这样，一力面可以使轧辊经热处理店的内应力分朽均勾；另一方面在轧辊表面淬火时，可对轧辊通水冷却，提高淬火效果。

Practice shows that， with double bath head is in use，sleeper厂， insert groove wall is easy to crack， at present common processing platform with the cuff instead of double slot for tap.

Cold roll diameter of more than 400mm， after forging， mostly in the 7L center. A 670 250mm. So， on one hand can make the roller stress heat treatment shop allocation hook are; on the other hand，sleeper谁家好， the roll surface quenching， the water cooling roller， improve the quenching effect.
