轧辊在轧机中的使用效果不但取决于轧辊材质及其冶金质量，还和使用条件、轧辊设计、操作维护有关。不同类型轧机的轧辊使用条件有很大差异，造成差异的因素有：轧机条件。如轧机类型、轧机和轧辊设计、孔型设计、水冷条件和轴承种类等。
The use effect of roll in the rolling mill not only depends on the material and metallurgical quality of the roll, but also is related to the conditi of use, the design of the roll and the operation and maintenance. The use conditi of the rolls for different types of rolling mills are very different. The factors that cause the difference are the rolling mill conditi. Such as rolling mill type, rolling mill and roll design, pass design, water cooling condition and bearing type and so on.
轧辊在制作和运用前的预备工序中会发生剩余应力和热应力。运用时又进一步遭到了各种周期应力的效果,包含有曲折、改变、剪力、接触应力和热应力等。
Residual stresses and thermal stresses will occur in the preparatory process before making and applying rolls. When applied, it is further affected by various cyclic stresses, including twists, changes, shear forces, contact stresses and thermal stresses.
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，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.
线材轧机拥有粗轧机架和与小型型材轧机类似的中间机架。与两线轧制的小型型材轧机相比，这些轧机一般被设计成可以进行高达4线的同时轧制的切分轧制。然而，目前的发展趋势是采用单线的高速轧制。
The wire mill has a roughing mill stand and an intermediate rack similar to a ***all section mill. Compared with the two section rolling mill, these mills are generally designed for rolling up to 4 lines at the same time. However, the current development trend is single line high-speed rolling.
