Abstract: The rolling deformation of high-intensity and thin tinplates was investigated for an HCM skin pass mill by FEM method and field experiment. Some reasons for higher actual roll force and poor flatness were revealed, and the solutions to these problems were determined. Based on the FEM analysis and roll profile design software, a new polynomial curve of the intermediate roll profile was proposed. Practical applications showed that the forced-contract was mitigatory, i. e., the actual roll force decreases by 10% to 20% and the actual elongation increases by 0.1% to 0.2%.
