Steel Coil Levelers fall into four categories: Leveling is the process of straightening through a number of offset rolls, usually from 13 to 23, with a smaller diameter. Typically these machines are backed up with rolls behind the work rolls to minimize deflection.
Corrective Leveling is configured like a basic steel coil leveler. However the backups are fully adjustable to create bend in the rolls. A corrective leveler can reduce shape defects across the strip and remove the entire coil set. These levelers are 17 to 23 work rolls and have adjustable backups. Some may have a 5HI or 6HI configuration for surface-critical material such as painted or stainless steel.
Tension Leveling is the ultimate in corrective leveling. The material is run through an entry and exit set of bridle rolls – with the corrective leveler located between them. The strip is under great tension with a slight elongation above the yield point of the material and is simultaneously leveled. The material is shape corrected and relieved of most internal stresses. This process usually involves a dedicated line.
No matter how simple or complex your leveling needs, a Galaxie sales engineer is able to match the best machine to meet your coil leveling goals. We carry Herr Voss, Paxson, Mesta, Bronx, and Stamco, to name a few.
