Intermediate Roll
Work rolls and intermediate rolls have to withstand great rolling stress during the working process. In addition to the strip welding seam, inclusions, edge cracks and other problems of the coming strip, it is easy to cause instantaneous high temperature, which will cause the work roll to be subjected to strong thermal shock and cracks , Sticky roller, peeling. Therefore, cold-rolling work rolls and intermediate rolls must have the ability to resist cracking and peeling caused by bending stress, torsion stress, and shear stress. At the same time, they must also have high wear resistance, high contact fatigue strength, high fracture toughness and Thermal shock strength, etc. Our company uses 9Cr, 9Cr2, 9CrV, 9Cr2W, 9Cr2Mo, 60CrMoV, 80CrN13W, 8CrMoV and has developed a series of new materials to increase the service life of the rolls which reach the international advanced level.
