Objective
It is often difficult to cold roll slit strip and uniform strip quality cannot always be guaranteed, the reason being the wedge-shaped or asymmetrical cross- section of the slit strip. Several studies, evaluations and assessments have shown that slit strip with asymmetrical thickness profile will drift sideways on the coiler during coiling until the weight has balanced out. On the other hand, this leads to undesired telescoping of the coiled strip and to stress- related warping in the strip. Pilot trials using a specially designed guide roller system were planned in view of counteracting these disruptive effects during the slit strip rolling process. This control system which has to be optimised as to geometry and roll operation during the pilot trials, will be subsequently verified for suitability in an industrial slit strip rolling mill.
