摘　　要：CPE轧管工艺是经过改良的顶管工艺,但其仍然存在成品管长度短、金属收得率低、生产能力低等缺点。为提高该轧管工艺的成材率,武钢集团汉阳钢厂通过具体分析CPE机组缩口工艺的特点,提出了CPE机组减少金属切头损失的工艺创新思路,改进缩口工艺,实施不切"杯底"的技术措施。此技术已在该厂Φ114mmCPE机组上应用并取得良好效果。Although the CPE pipe-rolling process is in fact a well-modified push bench process, it has disadvantages as rather limited length range of finished tubes, low metal yield and small production capacity, etc. Based on analysis of characteristics of the CPE plant＇ s tube-end pointing process, some proposals are put forward by the Hanyang Steel Works, Wuhan Iron and Steel （Group） Corporation to reduce the metal loss of the plant, including improvement of the tube-end pointing process and taking non- ＂cup bottom＂-cutting technique. The innovative technology has been applied to the Ф114 mm CPE plant of the company, resulting in satisfactory effectiveness.
