(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.
硬质合金辊环广泛应用于高速线材轧机的精轧机架，以及部分高速线材轧机的预精轧机架和棒材轧机的精轧机架。硬质合金轧辊的优点是硬度高、耐磨性好，单槽轧钢量可以达到高速钢轧辊的两倍。
The cemented carbide roller ring is widely applied to the finishing mill housing of high-speed wire rod mill, as well as the finishing mill for some high speed wire rod mill and the pre finishing mill and bar mill. The biggest advantage of the hard alloy roll is high hardness and good wear resistance, and the amount of single groove rolled steel can reach two times of the high speed steel roll.
轧辊的品种和制造工艺随冶金技术的进步和轧钢设备的演变而不断发展。中世纪轧制软的有色金属时使用强度低的灰铸铁轧辊。18世纪中叶英国掌握了轧制钢板用的冷硬铸铁轧辊的生产技术。
The variety and manufacturing process of roll h***e been developed with the progress of metallurgical technology and the evolution of steel rolling equipment. The use of low strength gray iron rolls in the Middle Ages when rolling soft nonferrous metals. In the middle of the eighteenth Century, Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.
按轧辊材质分有钢轧辊、铸铁轧辊、硬质合金轧辊、陶瓷轧辊等；按制造方法分有铸造轧辊、锻造轧辊、堆焊轧辊、镶套轧辊等；按所轧钢材状态分有热轧辊、冷轧辊。各种分类可以相应组合而使轧辊有更明确的含义，如热轧带钢用离心铸造高铬铸铁工作辊。
According to the roller material, there are steel rolls, cast iron rolls, hard alloy rolls, ceramic rollers, etc. according to the manufacturing method, there are casting rolls, forging rolls, hardfacing rolls, inlaid rolls and so on. According to the rolled steel status, there are hot rollers and cold rollers. Various classificati can be combined to make the roll more explicit, such as the casting of high chromium cast iron working roll for hot rolled strip.
