生产长材产品的轧机种类繁多，因此，轧机类型的选择、布局，轧辊材质的选择、轧辊尺寸的确定，选择范围也非常广。同时，轧辊报价，不同的轧机所选择的轧辊也是不相同的，需要根据生产要求选择轧辊。

There are a wide variety of rolling mills to produce long timber products. Therefore，轧辊， the selection and layout of the type of rolling mill， the selection of the material of the roll and the determination of the size of the roll are also very wide. At the same time， the rolls chosen by  rolling mills are also the roller should be selected according to the production requirements.

（1）堆焊前需先将轧辊辊身表面的疲劳层或缺陷，尤其是裂纹必须彻底清除；  

（2）在堆焊时，轧辊厂家，为了防止裂纹的产生，轧辊生产厂家，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， and the preheating temperature should be determined according to roll rolls and surfacing materials.

轧辊的品种和制造工艺随冶金技术的进步和轧钢设备的演变而不断发展。中世纪轧制软的有色金属时使用强度低的灰铸铁轧辊。18世纪中叶英国掌握了轧制钢板用的冷硬铸铁轧辊的生产技术。

The variety and manufacturing process of roll h**e been developed with the progress of metallurgical technology and the evolution of steel rolling equipment. The use of low strength gray iron rolls in the Middle Ages when rolling soft nonferrous metals. In the middle of the eighteenth Century， Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.
