连轧管机用芯棒的发展状况

重点介绍了国内外连轧管机用芯棒的基本生产工艺、芯棒制造企业的生产技术装备和芯棒的生产与需求情况,并对国内外芯棒的发展状况进行了对比。分析认为,目前连轧管机芯棒产品尚有一些国际市场发展前景。指出,我国生产连轧管机用芯棒的装备水平基本达到国际先进水平,产品质量也达到了国际水平,但在材料成分和综合性能控制方面尚有差距。建议制定芯棒制造的国家标准或行业标准,生产企业需注意对芯棒的服役条件进行系统研究。

Development Situation of Mandrel for Continuous Rolling Pipe Mill

Focused on are the development situations of the continuous rolling pipe mill-used mandrel both at home and abroad,covering such aspects as basic manufacturing process,production equipment of the mandrel maker and the supply-demand circumstances. Also presented in the paper is a comparison of the mandrel development in China with that abroad. Based on the analysis by the writer,it is identified that there still exists some world market potential for such product. It is also concluded that the domestic equipment level for manufacture of the said mandrel has been up to relevant international advanced level,and the product quality up to relevant world level as well,whereas a gap is not yet eliminated in terms of material composition and control of overall performance of the product. Furthermore,relevant suggestions are proposed,including establishing the national standard and the industrial standard for manufacture of the mandrel,and further focusing by the mandrel maker on systematic research on operation conditions of the mandrel.
