(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.
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；Therollbodyofastriprollingmilliscylindrical,andtherollbodyofthehotdryplateisslightlyconc***e。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.
既避免机械加工，又无补焊热应力热影响，修正厚度也不受***，一起产品所具有的耐磨性及金属材料不具备的退让性，确保修正部位的接触协作。
Not only to ***oid mechanical processing, but also to weld hot stress and heat, the correction thickness is not bound, and the wear resistance of a product and the non - concession of metal materials are not ***ailable, so as to ensure a hundred percent contact and cooperation of the corrected parts.
