The most commonly used materials of 0d2 roll die are high carbon, high chromium, high wear resistance and toughness. In addition to some welding rolls D4 D5 D6 - compared with D2, higher grade D series are used to improve wear resistance
1.8 rolling defect rolling mill spring refers to the defect that the thickness of rolled steel plate is greater than the required thickness, because the roll deflects under high rolling force. The mill has elastic deformation. If we roll the roll with higher stiffness, that is, the stiffness of the roll can be avoided

In today's hot rolling mills, achieving the expected life of high-speed steel rolls depends on one person's successful roll cooling strategy and successful management of heat transfer problems. In addition, effective cooling of hot and cold mills has proven to be more important to today's standards
Traditionally, hot rolling of steel is carried out with rolls made of cast iron, steel or cemented carbide. According to Roberts 1983, abrasive wear of hot-rolled metal rolls is caused by local slip during rolling. Abrasive wear occurs in the polishing of metal rolls. The initial wear marks are removed from the surface of rolls or used as polishing...
