Leveling process of straightening machine

Source:     Time:2020-04-27 Hits:

Have you heard about straightening machine before? The straightening machine also called the leveler,it is used for thick plate leveling. When choosing the straightening machine, there’s some important factors to consider which are the roll diameter, the roller pitch and the number of work rolls. A straightening machine is the best choice to a straightener as the straightening machine will remove more than cross bow or coil set.

The following are the leveling process of straightening machine:

 

1. Leveling is achieved by accurately bending the metal strip back and forth as it passes through a series of small-diameter offset rolls. The gap between the rolls is set independently on a leveler’s entry and exit. The entry rolls should be deeply nested, as this forces the material through extreme angles to erase memory caused by trapped internal stresses. This is also known as ‘plunge’, a technique for removing strip memory.

 

2. The straightening machine uses adjustable pressure points called flights, under the rolls to raise and lower them to an exact position. By adjusting a work roll’s shape, the material’s path length can be altered through the straightening machine. A longer path length allows the material to be stretched more because more work is being performed on it as it passes through the rolls.

 

3. It’s now time to re-set the strip’s memory to flat as it leaves the straightening machine. The appearance of the material that will be shipped to the end-user is achieved in the final three roll clusters. If the roll gap is set too deep, the material will be forced upward by the last roll, which will create an up-bow. It is normal to set the straightening machine’s exit gap near the materials’ gauge. This is a simple, but important rule to follow.
