    From MPM to PQF——Looking back and Prospects of Development of Retained-mandrel Pipe Mill

    • 摘要: 敘述了限動(dòng)芯棒連軋管機(jī)的發(fā)展情況,從工藝使用角度論述不同時(shí)期限動(dòng)芯棒連軋管機(jī)的特點(diǎn)。重點(diǎn)介紹了PQF連軋管機(jī)在生產(chǎn)工藝、設(shè)備結(jié)構(gòu)等方面的特點(diǎn)。對(duì)PQF軋管機(jī)的牌坊及工作機(jī)架在軋管時(shí)所承受的軋制力進(jìn)行了簡(jiǎn)要分析;討論了相關(guān)工藝問(wèn)題并展望了限動(dòng)芯棒連軋管機(jī)的發(fā)展前景。

       

      Abstract: Described in the article is the development history of the retained mandrel pipe mill, covering analysis of the features of the retained-mandrel pipe mill at different stages of its development from the point of view of technological application, and focusing on characteristics of PQF mill in manufacturing process and equipment configuration. The rolling force imposed upon the mill frame and the roll stand of PQF mill is also roughly analyzed, and relevant technological issues are discussed and the future development of such type of pipe-rolling mill is looked ahead.
