摘　　要：介绍了唐钢第二钢轧厂二棒生产线的Φ22 mm螺切分轧制工艺的研究开发情况,重点介绍了Φ22 mm螺切分轧制的孔型系统和导卫系统。切分工艺应用后,彻底解决了5#连铸机与二棒生产能力不匹配的问题,提高了产品产量,取得了较好的经济效益。It is introduced the research and development of splitting rolling process for φ22 mm reinforced bar in second bar production line of No. 2 Steel Rolling Mill of Tang Steel, especial its pass and guide sys- tems. After applied the process solves thoroughly the problem of mismatching between the capacities of 5# caster and the second bar line, the output increased, good economic profit got.
