轧辊在制作和运用前的预备工序中会发生剩余应力和热应力。运用时又进一步遭到了各种周期应力的效果，包含有曲折、改变、剪力、接触应力和热应力等。

Residual stresses and thermal stresses will occur in the preparatory process before making and applying rolls. When applied， it is further affected by various cyclic stresses， including twists， changes，轧辊报价， shear forces，轧辊采购， contact stresses and thermal stresses.

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，轧辊厂家，可对轧辊通水冷却，提高淬火效果。

Practice shows that， with double bath head is in use， 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，轧辊， on one hand can make the roller stress heat treatment shop allocation hook are; on the other hand， the roll surface quenching， the water cooling roller， improve the quenching effect.

轧辊的品种和制造工艺随冶金技术的进步和轧钢设备的演变而不断发展。中世纪轧制软的有色金属时使用强度低的灰铸铁轧辊。18世纪中叶英国掌握了轧制钢板用的冷硬铸铁轧辊的生产技术。

The variety and manufacturing process of roll h***e been developed with the progress of metallurgical technology and the evolution of steel rolling equipment. The use of low strength gray iron rolls in the Middle Ages when rolling soft nonferrous metals. In the middle of the eighteenth Century， Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.
