轧辊的分类方法有多种，主要有：（1）按产品类型分有带钢轧辊、型钢轧辊、线材轧辊等；（2）按轧辊在轧机系列中的位置分有开坯辊、粗轧辊、精轧辊等；（3）按轧辊功能分有破鳞辊、穿孔辊、平整辊等。

There are many classification methods like roller are: (1) according to the type of product with strip roller, steel roller, wire roller; (2) according to the roll in rolling mill series in the of divided blooming rolls, roughing roll, finishing roll; (3) according to the function of a roller descaling Kong Gun, wearing roller, flat roll etc.

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.
