单机架轧机轧制Ф270mm～Ф300mm热轧圆钢的开发

The Development of Rolling Φ270 mm～Φ300 mm Hot-rolled Round Steel by Stand-alone Frame

介绍棒材厂在Ф750 mm单机架轧机上开发Ф270 mm～Ф300 mm热轧圆钢的工艺过程。通过选择设计适合初轧机轧制圆钢的孔型系统及工艺制度,包括孔型系统设计、轧辊孔型加工、加热制度、轧制制度、压下规程,使轧钢设备与工艺相匹配,开发出Ф270 mm～Ф300 mm圆钢,解决了生产过程中存在的难点问题。

Process of developing Φ270 mm~Φ300 mm hot rolled round steel by 750 mm single standrolling mill at the Bar Plant.By selecting the pass system and process system designed toaccommodate the early rolling round bar,including the design of the pass system.rolling roll passprocessing,heating system, the rolling system.rolling schedule,rolling equipment matches totechnology,Φ270-Φ300 mm round bar was developed.the difficult problems that exist in theproduction process were solved.
