什么是铸造轧辊，铸造轧辊主要有哪些种类？

铸造轧辊是指将冶炼钢水或熔炼铁水直接浇注成型这一生产方式制造的轧辊种类。

铸造轧辊按材质又可分为铸钢轧辊和铸铁轧辊两类；按制造方法又可分为整体铸造轧辊和复合铸造轧辊两类。

What are the casting rolls and what are the main types of casting rolls?

The casting roller refers to the type of rolls produced by direct casting of molten steel or molten iron.

The casting roll can be divided i* two types: cast steel roll and cast iron roll according to material quality. According to the manufacturing method，crane谁家好， it can also be divided i* two types: integral casting roll and compound casting roll.

（1）堆焊前需先将轧辊辊身表面的疲劳层或缺陷，尤其是裂纹必须*清除；

（2）在堆焊时，为了****裂纹的产生，必须先加工轧辊辊身预热，预热温度根据轧辊辊及堆焊材料而定。

(1) before welding， the fatigue layer or defect of the roller body surface must be first removed， especially the crack must be thoroughly removed.

(2) in the process of surfacing， in order to prevent cracks， the roller body must be pre heated，营口crane， and the preheating temperature should be determined according to roll rolls and surfacing materials.

轧辊由辊身、辊颈和轴头二部分组成。辊颈安装在轴承中，crane报价，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，crane哪里有， 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.
