Frequently Asked Questions About Levelers in Coil Processing Equipment
Levelers are essential to most manufacturers’ coil processing and feeding lines. Here are some common questions about levelers that our customers ask:
What Are Some Common Features of Levelers?
- Roll diameter, roller pitch, and the number of work rolls are essential factors to consider when selecting the best machine for your needs.
- Work rolls can be backed up for more precise flatness and zone control.
- You can maximize your results by creating a closer roller pitch and smaller leveling roller diameter.
- Unlike a typical straightener, a good leveler will remove more than a cross bow or coil set.
- Newer levelers offer automatic roll positioning for different thicknesses and materials and an automatic roll calibration control option, simplifying adjustments for newly reground roll diameters following roll changes.
What Are Levelers on Cut-to-Length (CTL) Lines
- The most common use for leveling equipment is on cut-to-length lines.
- In some lines, the leveler comes after the shear, which means the material is leveled in plate or sheet form.
- Newer lines have fewer problems when leveling the coil before shearing.
- Stopping and starting a leveler with every length of feed into a shear is a bad idea as it will cause excessive wear on the leveler’s drive train and possibly leave set marks on cold-rolled surfaces.
- Most lines use looping pits or flying shears with the leveler first going slow, then fast.
- Because levelers have a limited range for maximum or minimum material thickness, using two levelers—a big one and a smaller one—is common to extend the capacity of a cut-to-length line.
