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, 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, the roll surface quenching, the water cooling roller, improve the quenching effect.

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，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。RolledsteelTherolledsteelisthekeyfactortoselecttheroll。

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, spalling resistance, indentation resistance and thermal cracking performance.

当轧制其它型材时，可以用水平机架更换机架。水平机架的轧辊有很深的孔型，而机架没有。

较大直径的水平轧辊确定型钢的的形状，而较小直径的一对立辊用于轧制边部。当坯料穿过传统机架和机架精轧轧辊时，可以获得很好的表面光洁度和尺寸公差。

When rolling other profiles, the universal rack can be replaced with a horizontal rack. The roll of the horizontal frame has a very deep pass, but the universal rack does not.

Horizontal rolls with larger diameters determine the shape of the section steel, and a pair of rolls with ***aller diameters are used for rolling edges. Good surface finish and dimensional tolerance can be obtained when the blank passes through the conventional stand and universal stand finish rolls.
