摘　　要：高速棒材生产线道次多、压缩丰大,最后几道次应变速率快,经轧制强烈变形后的奥氏体品粒,存在大量的位错和亚晶组织,其位错密度更高利于成品性能提高。现新建的高速棒材生产线多通过模块轧机和控冷水箱实现控轧控冷以提高成品性能。但多模块热机轧制技术和模块轧机国产化设备的稳定运行应用在国内还属于探索期,存在无先例和相关经验及标准可借鉴的现状。所以对高速棒材模块轧机国产化设备的稳定运行的研究具有重大意义。High-speed bar production line has many passes,large compression,and fast strain rate in the last few passes.After rolling,there are a lot of dislocations and sub-crystal structures in austenite grains,which has higher dislocation density and is beneficial to improve the performance of the finished product.At present,the newly built high-speed bar production line mainly realizes controlled rolling and controlled cooling through modular rolling mill and controlled cooling water tank to improve the performance of finished products.However,the application of multi-module hot mill rolling technology and the stable operation of the domestic equipment of modular rolling mill is still in the exploratory stage in China,there is no precedent and relevant experience and standards can be used for reference.Therefore,it is of great significance to study the stable operation of domestic equipment for high-speed bar module rolling mill.
