(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.

弄清轧辊的使用条件以及在同类型轧机中所用轧辊的失效方式，了解当前各种轧辊材质的性能和制造工艺，才能较正确地制定该轧机用辊的技术条件和选用合适而经济的轧辊材质。

We must know clearly the condition of the roller and the failure way of the roll used in the same type of rolling mill, and understand the performance and manufacturing technology of all kinds of roller material at present, so that we can correctly formulate the technical conditi of the roller and choose the right and economical roller material.

整体轧辊是相对于复合轧辊而言的，整体轧辊的辊身外层与心部以及辊颈采用单一材质铸造或锻造而成，辊身外层和辊颈不同的***、性能通过铸造或锻造工艺以及热处理工艺过程来控制和调整。

The whole roll is compared to the roll. The outer layer of the whole roll is made of a single material or forging with a single material. The structure and performance of the roll are and adjusted by the casting or forging process and the heat treatment process.

初轧机、钢坯连轧机、大型型钢和轨梁轧机、热轧板带钢轧机破鳞和轧边机、型钢轧机的轧边机，还有小型型钢、线棒材轧机的粗轧机架等轧机使用的轧辊，大多采用整体铸造方法生产，这类轧辊使用层较厚，孔型较深。

The rolling mill of rolling mill, billet rolling mill, large type steel and rail beam mill, hot rolled strip mill break scale, rolling edge mill, type steel universal mill, and rolling mill used in ***all steel and wire rod mill are mostly produced by the whole casting method, which is thicker and deeper.
