sleeper谁家好_圣霖国际_长春sleeper

生产长材产品的轧机种类繁多，因此，轧机类型的选择、布局，sleeper谁家好，轧辊材质的选择、轧辊尺寸的确定，选择范围也非常广。同时，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，sleeper厂， the rolls chosen by  rolling mills are also the roller should be selected according to the production requirements.

而精轧辊速度较高，轧制较终产品要有一定的表面质量，对它以硬度、耐磨等为主要要求。然后考虑轧辊使用时所应有的耐磨性。由于轧辊的磨损机理很复杂，包括机械应力作用、轧制时的热作用、冷却作用、润滑介质的化学作用以及其他作用。

And the high speed of the fine roller，sleeper价格， the final product of rolling must have a certain surface quality，长春sleeper， which is the main requirement for its hardness， wear resistance and so on. Then the wear resistance should be considered when the roll is used. Because the wear mechanism of roller is very complicated， including mechanical stress， thermal action during rolling， cooling effect， chemical action of lubricating medium and other functions.
