摘要
极薄带冷轧给轧制生产带来了挑战,其中包括接触力学、带材的凸度和表面质量。在考虑工作辊边部接触的前提下,采用自行开发的改良影响函数法对薄带的对称和非对称冷轧过程进行了分析。文章的重点是通过薄带冷轧来阐述辊缝接触力学,分析辊缝处的摩擦对轧制力学和带材凸度的影响,同时还对轧辊边部接触对轧制力学和带材凸度影响进行了讨论,认为轧辊边部接触将对工作辊边部磨损产生影响,并对轧制力计算值与实测值进行了比较。
Cold roiling of thin strip is a challenge in roiling practice, which involves the contact mechanics, strip crown and the surface finish. Using a developed modified influence function method, the cold roiling of thin strip in both symmetric and asymmetric cases were analysed with considering work roll edge contact. This paper addresses the cold roiling of thin strip to justify the roll bite contact mechanics, and to analyse the effects of the friction in the roll bite on roiling mechanics and strip crown. The effects of roll edge contact on roiling mechanics and strip crown are also discussed, Roll edge contact will affect the wear of work roll edge, and the calculated rolling forces are compared with the measured values.
