SUMMARY:Contactless strip shape measurement for silicon steel grade rolling
DESCRIPTION:"Silicon steel grade sheets are essential to e-mobility. The material is hard, thin, and brittle, especially at the edges. With thinner gauges, magnetic losses are reduced, but the filling factor increases with more sheets. Therefore, the permeability and magnetization diminish. Contactless flatness measurement is beneficial for reducing the risk of strip breaks from edge cracks and to control flatness also at lower rolling speed. 
Additionally, it helps to get faster into the tolerances at the strip head since the response time due to the measuring principle is constant. Compared with flatness rolls which have to turn to get measurement readings the contactless principle allows to measure independently from a rotating roll or strip movement.
Primetals Technologies has developed contactless flatness measurement consisting of actuators to oscillate the strip and eddy current sensors to detect inhomogeneities of the internal tensions.
Since there is no contact with the strip, surface quality is maintained, and no wear occurs. Because of the straight forward construction, compared to a flatness roll, a maintenance can be done on site by the service personal in short time."
