    中文摘要

    On the basis of integrating two-dimensional varying thickness finite element method with hybrid genetic algorithm, a precise model was developed to design ideal backup roll contour (Varying Contact Backup Roll, in short VCR) in finishing trains of hot rolling rapidly and efficaciously. Additionally, a lot of good actual effects of VCR, such as evident improvement of profile and flatness of strip, remarkable decrease of roll consume, excellent maneuverability and maintenance, and so on, were validated by long-term industrial tests in hot rolling strip plant of Wuhan Iron and Steel Group Corporation (WISCO).
