Even with the use of the most up-to-date technology, flatness defects along with internal stresses cannot be avoided during the manufacture of hardened and tempered plate. Therefore, it is essential to use plate levelers after heat treatment, reducing internal stresses at the same time. Plate levelers are most often used for leveling thin or heavy
Rolling mills are classified according to the number and arrangement of the rolls. A two high rolling mill can further be classified as a reversing and a non-reversing mill. All rolling mills have common construction that is independent of the specific type of rolling required: 1. Backup rolls – are intended to provide rigid support
Unlike a traditional rolling mill, a Z-High® mill is a 20-high cluster mill configuration that utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality. As a result, very hard
There are two main goals behind the science of leveling metal strips. One is to make the surface flat, and ripple-free. The second is to eliminate any hidden internal stresses that can cause the strips to twist and bow during subsequent operations, such as stamping. When choosing the right corrective leveler, there’s some important factors
