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.
不同类型的轧机以及同类型而使用条件不同的轧机，对所用的轧辊性能要求不尽雷同，如方坯和板坯初轧机轧辊要具有好的扭转和弯曲强度、韧性、咬入性、抗热裂性和热冲击性以及耐磨性；而热带精轧机架要求轧辊辊面的高硬度、抗压痕、耐磨、抗剥落和耐热裂等性能。
Different types of rolling mill and the same type and the use of different conditi on properties of roll mill， requirements for not identical， such as billet and slab mill roll with good torsional and bending strength， toughness， bite， thermal cracking resistance and thermal shock resistance and abrasion resistance; tropical finishing stand requirements the roller surface hardness， wear resistance， spalling resistance， indentation resistance and thermal cracking performance.
当轧制其它型材时，crane rail价格，可以用水平机架更换机架。水平机架的轧辊有很深的孔型，而机架没有。
较大直径的水平轧辊确定型钢的的形状，crane rail生产商，而较小直径的一对立辊用于轧制边部。当坯料穿过传统机架和机架精轧轧辊时，crane rail厂家，可以获得很好的表面光洁度和尺寸公差。
When rolling other profiles，铁岭crane rail， the universal rack can be replaced with a horizontal rack. The roll of the horizontal frame has a very deep pass， but the universal rack does not.
Horizontal rolls with larger diameters determine the shape of the section steel， and a pair of rolls with ***aller diameters are used for rolling edges. Good surface finish and dimensional tolerance can be obtained when the blank passes through the conventional stand and universal stand finish rolls.
