Detailed Description

High precision leveller with inspection mirror Number of chrome plated rolls: 19 Size of levelling rolls: ≤ Φ 55mm - 0.12mm Levelling thickness: ≤ 0.525mm Levelling width: ≤ 1100mm There are 4 different categories of Steel Coil Leveler. Starting from the most basic: straightening or flattening, this is the process of removing coil set or cross bow out of flat rolled material or a steel sheet. Generally, a flattener has 5 to 9 offset rolls, with relatively large diameter rolls. Typically a flattener is in press feed application, or used in a simple cut to length line. 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: This is configured like a basic steel coil leveler, however the back ups are fully adjustable to create bend in the rolls. A corrective leveler can reduce shape defects across the strip and remove all of the coil set. These levelers are 17 to 23 work rolls, and have adjustable back ups, 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 a entry and exit set of bridle rolls, with the corrective leveler in between. The strip is under great tension with a slight elongation above the yield point of the material, and 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 are, a professional sales engineer at Zhongcheng, awaits your phone call or email, to best suit the desired machine for your coil leveling needs.
