轧辊采购-轧辊-圣霖国际【精益求精】

轧辊由辊身、辊颈和轴头二部分组成。辊颈安装在轴承中，并通过袖承座和压下装置把轧制力传给机架。铂头和连接轴相连接，传递轧制扭矩。轴头有三种主要形式；梅花轴头、万向轴头、带键槽的或圆柱形轴头。

The roll is of two parts of the roller body，轧辊设备， the neck of the roll and the shaft head. The roll neck is installed in the bearing and passes through the sleeve bearing seat and the press down device to the rack. The platinum head is connected to the connecting shaft to transfer the rolling torque. There are three main forms of the shaft; the shaft of a plum，轧辊采购， a universal shaft，轧辊， or a cylindrical shaft with a keyway.

轧辊在轧机中的使用效果不但取决于轧辊材质及其冶金质量，还和使用条件、轧辊设计、操作维护有关。不同类型轧机的轧辊使用条件有很大差异，造成差异的因素有：轧机条件。如轧机类型、轧机和轧辊设计、孔型设计、水冷条件和轴承种类等。

The use effect of roll in the rolling mill not only depends on the material and metallurgical quality of the roll， but also is related to the conditi*** of use，轧辊哪家好， the design of the roll and the operation and maintenance. The use conditi*** of the rolls for different types of rolling mills are very different. The factors that cause the difference are the rolling mill conditi***. Such as rolling mill type， rolling mill and roll design， pass design， water cooling condition and bearing type and so on.

轧辊中大量使用合金元素是在第二次***以后，这是轧钢设备朝着大型化、连续化、高速化、自动化发展以及轧材强度提高、变形抗力加大后对轧辊性能提出更高要求的结果。

A large number of alloying elements in the rolls are produced after the Second World War.the result of rolling mill's large performance， continuous， high-speed and automatic development， as well as the increase of rolling strength and resistance to deformation.
