摘　　要：通过对无孔型轧制的工业试验和技术分析,得出无孔型轧制可在大间距轧机上实现,脱方控制的关键点是导卫控制和宽展控制,翻平宽展能使轧件产生圆弧钝角,避免了应力集中和裂纹,采用无孔型轧制具有可统一坯料、提高轧辊寿命2～4倍、降低能耗6%～7%等优点。The analysis of the application of grooveless roiling technology proves that grooveless roiling can be successfully realized in the big-distance mills. The key point of off-square control is the control of guide and turn over spread, of which the turn over spread can help rolled piece to form arc obtuse angle. The application of grooveless rolling can simplify the billets, increase the roll life 2 to 4 times and reduce energy cost by 6 to 7 per cent.
