异步轧制技术作为一种制备高性能超细晶材料的剧烈塑性变形方法主要应用于箔材和带材的生产。通过调整轧机上下辊的辊径实现异步轧制,采用该技术制备5182铝合金热轧厚板,并研究剪切变形和板形控制。结果表明:异步轧制对金属塑性流动具有重要影响,并在一定程度上细化微观组织,提高组织、性能的均匀性,异步轧制也可以降低轧制力。在异步轧制过程中经常出现轧板弯曲现象,同时探讨了影响轧板弯曲的因素。 Asynchronous rolling technology as a preparation of high-performance ultrafine grained plastic deformation method is mainly used in the production of foil and strip. By adjusting the roll diameter of the upper and lower rolling mill to realize the asynchronous rolling, 5182 aluminum alloy hot-rolled thick plate was prepared by this technology, and the shear deformation and shape control were studied. The results show that asynchronous rolling has an important influence on the plastic flow of metal and to a certain extent refine the microstructure and improve the uniformity of microstructure and properties. Asynchronous rolling can also reduce the rolling force. During the process of asynchronous rolling, the phenomenon of the bending of the rolling plate often appears, and the factors that affect the bending of the rolling plate are also discussed.
