初轧机、钢坯连轧机、大型型钢和轨梁轧机、热轧板带钢轧机破鳞和轧边机、型钢轧机的轧边机，还有小型型钢、线棒材轧机的粗轧机架等轧机使用的轧辊，圣霖国际吊车轨，大多采用整体铸造方法生产，这类轧辊使用层较厚，孔型较深。

The rolling mill of rolling mill，圣霖国际吊车轨价格， billet rolling mill， large type steel and rail beam mill， hot rolled strip mill break scale， rolling edge mill， type steel universal mill， and rolling mill used in small steel and wire rod mill are mostly produced by the whole casting method， which is thicker and deeper.

（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，为了防止裂纹的产生，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，圣霖国际吊车轨厂， 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，圣霖国际吊车轨生产， 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 have 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.
