This research project has investigated methods for adhering to the increasingly strict requirements for specific steel strip flatness profiles. Tests in the laboratory and on two 7-stand hot strip rolling mills examined the relative influence of strip thickness, reduction per pass, strip profile shape and longitudinal tensile stresses on strip thickness profile. Results demonstrated a boundary region at 8 mm to 10 mm thickness below which strip profiles cannot be effectively influenced due to restricted transverse material flow. This boundary thickness is greater for harder steel grades. Tests demonstrated that is most efficient to carry out profile changes in those stands where the thickness is between 8 mm and 16 mm.
