轧辊中大量使用合金元素是在第二次以后，圣霖吊车轨，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，圣霖吊车轨生产， high-speed and automatic development， as well as the increase of rolling strength and resistance to deformation.

硬质合金轧辊是在硬质合金刀具的基础上发展而来的，硬质合金是采用坚硬的碳化钨颗粒硬质相与镍、钴等黏结相金属烧结而成。硬质合金的性能取决于碳化钨颗粒尺寸的大小和黏结相金属含量的多少，当黏结相金属中含有一定量的镍和铬时，不仅会大大提高轧辊的抗热疲劳性能。

Cemented carbide rolls are developed on the basis of cemented carbide tools. Cemented carbide is made of hard tungsten carbide particles and hard phase sintered together with nickel and cobalt bonded phases. The properties of cemented carbide depend on the size of tungsten carbide particle and the content of bonding phase metal. When the amount of nickel and chromium in the bonding phase contains metal， it will not only greatly improve the thermal fatigue resistance of the roller.

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，圣霖吊车轨生产厂家，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，圣霖吊车轨报价， 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， a universal shaft， or a cylindrical shaft with a keyway.
