We provide Tension leveling lines to remove any shape defects present in the Coiled material. In the steel industry stringent tolerances for the end product necessitates the requirement for Tension leveling of the Coil product to remove any edge to edge length differential, such as so called ‘edge waves’.
With Tension leveling, all parts of the Coil strip are pulled past the yield point, top to bottom, edge to edge. All the trapped stress is removed in the process & the strip pulled out is relatively free of the internal stresses.
The Tension Leveller arrangements include of an undriven leveller with entry and exit bridles. In the automated lines the degree of elongation is determined by the difference in the speed or the tension generated between the bridles. The Tension levellers are available with different drive options such as closed loop mechanical differentials, all-electrical drives and combination electrical-mechanical drives.
