0.6% Elongation High-Speed High-Boron Steel Roll 2000mm (HSS Roll) With High Hardness
Product Description
The steel rolls are widely used in bar rolling mills, strip mills, roughing mill and ect. The main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. The roll is mainly composed of three parts: roll body, roll neck and shaft head. The roll body is the middle part of the roll that actually participates in rolling metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing, and the rolling force is transmitted to the stand through the bearing seat and the pressing device. The shaft head of the transmission end is connected with the gear seat through the connecting shaft, and transmits the rotating torque of the motor to the roller. The rolls can be arranged in the form of two rolls, three rolls, four rolls or multiple rolls in the rolling mill stand.
High speed steel rolls, produced by horizontal centrifal casting process, are all compound rolls with high speed steel as the work layer and nodular iron as the core. The material of HSS contains plenty of alloyed elements such as Mo, V, W, Cr etc. The high hardened eutectic carbides & second carbides, such as MC, M2C, M6C evenly distributed in tempered martensitic matrix, make the wear and thermal cracking reistance very excellent. Besides, the resistance to surface roughing is also good. In codition of hot rolling, the contact points between steel strip and the work rolls can form a thin adherent oxide film on the roll surface, which plays a good role in the wear features and the quality of the strip surface. HSS rolls are mnly used as the work rolls in the hot strip mills and the finishing stands of bar mills; rings of the universal section mills and finishing stands of the high speed bar mills
