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，crane价格， it will not only greatly improve the thermal fatigue resistance of the roller.
（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，沈阳crane，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.
生产长材产品的轧机种类繁多，crane哪家好，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，crane哪里有，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， 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.
