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.

轧机上使金属产生连续塑性变形的主要工作部件和工具。轧辊主要由辊身、辊颈和轴头3部分组成。

辊身是实际参与轧制金属的轧辊中间部分。它具有光滑的圆柱形或带轧槽的表面。辊颈安装在轴承中，并通过轴承座和压下装置把轧制力传给机架。

The roller body is the middle part of the roll that actually takes part in rolling the metal. It has a ***ooth cylinder or a surface with a groove. The roller neck is installed in the bearing and passes the rolling force to the rack through the bearing seat and the press down device. .

线材轧机拥有粗轧机架和与小型型材轧机类似的中间机架。与两线轧制的小型型材轧机相比，这些轧机一般被设计成可以进行高达4线的同时轧制的切分轧制。然而，目前的发展趋势是采用单线的高速轧制。

The wire mill has a roughing mill stand and an intermediate rack similar to a ***all section mill. Compared with the two section rolling mill, these mills are generally designed for rolling up to 4 lines at the same time. However, the current development trend is single line high-speed rolling.
