SMS group has developed tension levelers for cold as well as hot strip lines, that are capable to level steel strip with yield points much higher than 1,000 megapascals. The machines are also suited for installation in existing plants to make these facilities meet future material requirements.
In strip processing lines, tension levelers minimize flaws such as waviness, cambers or longitudinal and transverse bends by a combined tensioning and levelling action to create a flat final product. In pickling lines, where it is called scale breaker, the tension leveler has to perform an additional task which is to break the scale layers by alternate bending and stretching to assure better pickling medium efficiency and hence a faster pickling process. Market demands for higher material strengths lead to exacting changes in machine technology.
One aspect is higher forces in stretching and bending.
