(1)软辊；肖氏硬度约为30一40，用于开坯机、大型型钢轧机的租轧机等。

(2)半硬辊：肖氏硬度约为40一60，用于大型、中型、小型型钢轧机和钢板轮机的租轧机。

(3)硬面辊：肖氏硬度约为60一85，用于薄板、中板、中型型钢和小型型钢轧机的稿轧机及四辊轧机的支撑辊。

(4)特硬辊le氏硬度约为85—100，用于冷轧机。

(1) soft roll; the hardness of Shaw is about 30 40. It is used for the renting rolling mill of the billet machine and the large steel mill.

(2) semi hard roll: the hardness of the Shaw is about 40 to 60. It is used for the renting rolling mill of large, medium, ***all type steel mill and steel plate turbine.

(3) hard roll: Shore hardness of about 60 to 85, for supporting roller mill release sheet, plate, medium and ***all steel mill and four roller mill.

(4) the hardness of the hard roll Le is about 85 - 100 for cold rolling mill.

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.
