轧辊是轧机的重要部件，按照轧机类型可分为领带轧机轧辊、型钢轮机扎辊和钢管轧机轧辊三大类。
板带轧机轧辊的辊身呈圆柱形，热乾板带轧辊的辊身微凹，当受热膨胀时，可保持较好的扳形。
Roll is an important part of the rolling mill. According to the type of rolling mill, it can be divided into three types: the tie mill roll, the type steel turbine ligation roll and the steel tube rolling mill roll.
The roll body of a strip rolling mill is cylindrical, and the roll body of the hot dry plate is slightly conc***e. When the heat is expanded, it can maintain a better shape.
轧机上使金属产生连续塑性变形的主要工作部件和工具。轧辊主要由辊身、辊颈和轴头3部分组成。
辊身是实际参与轧制金属的轧辊中间部分。它具有光滑的圆柱形或带轧槽的表面。辊颈安装在轴承中，并通过轴承座和压下装置把轧制力传给机架。
The roller body is the middle part of the roll that actually takes part in rolling the metal. It has a ***ooth cylinder or a surface with a groove. The roller neck is installed in the bearing and passes the rolling force to the rack through the bearing seat and the press down device. .
轧辊是轧机的核心部件，轧辊的使用涉及轧机使用时的类型选择、轧辊的准备、在轧制过程中的维修和周期性修整，而这些都全是影响轧机生产率、产品质量和生产经济性的因素。
Roll is the core part of the rolling mill. The use of the roll involves the type selection of the rolling mill, the preparation of the roll, the maintenance and the periodic dressing during the rolling process, all of which are all factors that affect the productivity of the rolling mill, the quality of the product and the production economy.
轧机布置和道次设计
机架在生产线的位置以及道次设计对轧辊的选择有很大影响。根据机架位置，轧辊的受力方式和性能可以有很大变化。这是因为应用于粗轧机架和精轧机架的轧辊有非常不同的受力方式，从而导致轧辊性能有预期的改变.
Rolling mill layout and pass design
The of the rack in the production line and the design of the pass h***e great influence on the choice of the roll. According to the of the frame, the force and performance of the roller can be greatly changed. This ibecause the rolls used in roughing mill stand and finishing mill stand h***e very different forces, resulting in expected changes in roll performance.
