摘要: 针对Φ114mm CPE(斜轧穿孔延伸)机组生产石油用管成材率低的问题,对生产工艺流程进行了分析。得出中间热锯切和热切头尾是导致成材率低的两个重要原因。通过采用改进的钢管下冷床对齐方法以及缩口工艺,使Φ73.0 mm×5.5 mm和Φ88.9 mm×6.5 mm的石油用管综合成材率由78%提高至84.5%~85.0%。

Abstract: In light of the problem of low yield of pipe for petroleum produced by Φ114mm cross roll piercing elongation(CPE)mill,an analysis on production process flow sheet has been carried out.  It is obtained that hot-sawing on pipe in middle procedure and hot-cutting ends are two factors led to low yield. With adopting the improved alignment method as pipe moved to cooling bed and the  pointing  process,the  comprehensive yield of Φ73.0  mm×5.5 mm and P88.9 mm× 6.5 mm pipes for petroleum increases to84.5%~85.0% from original 78%
