摘要
介绍了中频感应加热推挤式钢管扩径工艺,对扩径新老工艺经济技术条件进行了对比分析,结合三年来扩径生产实践,对主要工艺参数做了简介,提出了今后应注重研究探索的几个相关问题。
The expanding diameter process is desctribed.The economic and technical condition of the new and old expanding diameter process is compared and analyzed.With the practice of three years,the main technological parameter is introduced in brief, and some relevant problems to be studied in future is brought forward.
