分析介绍了热带无头轧制技术在板带高效、高精度轧制中的作用,国外在常规热连轧线上实现无头轧制的技术特点、应用效果及进展,以及最新的ESP技术的特点和最新发展。同时,也简要介绍了国内对热带无头轧制技术的关注以及初步研究探索情况。实践证明,热带无头轧制在减量化板带生产,即低成本大批量生产薄和超薄规格板带,提高板带的组织性能稳定性、均匀性、成材率及板厚板形精度、实现部分＂以热代冷＂等方面效果显著,是推动节能减排和现代板带轧制技术发展的方向,具有重要的研究开发价值和应用前景。

The effect of hot strip endless rolling process on high-efficiency and high-precision rolling,technical characteristics,application and latest progress of endless rolling on abroad conventional hot continuous rolling line and ESP line were introduced.Meanwhile,the domestic attention and preliminary research explorations on endless rolling technology were briefly introduced.It was proved by practices that endless rolling technology has significant effect on mass production for thin and ultra-thin strip with low cost,promoting microstructures uniformity and properties stability,improving thickness accuracy and profile quality and enhancing finished product rate,especially partly replacing cold-rolled sheet with hot-rolled thin strip.Hot strip endless rolling technology,as one of the development directions of modern strip rolling technologies for promoting energy conservation and emission reduction,had important research development value and application prospect.
