This project aimed to investigate the influential parameters of the mills through numerical simulations, data analysis and plant-based trials. Models to predict force and shape have been developed at CRM, and plant trials have shown that the shape prediction is dependent upon incoming strip profile. Skin pass rolling has been shown to cause deterioration in the work hardening coefficient, particularly in the non-ageing steel grades at Carlam. Analysis of residual stress measurements has shown a correlation between the surface residual stress values in the sheets and bow of the material after cutting. Roll heating trials have shown that the growth of the thermal camber is independent of the roll diameter and is a function of temperature increase only, for rolls of the same material.
