摘要: 限動(dòng)芯棒連軋管機(jī)經(jīng)過(guò)近20年的發(fā)展,工藝技術(shù)不斷完善,已成為無(wú)縫鋼管生產(chǎn)的主要機(jī)型。簡(jiǎn)介了限動(dòng)芯棒連軋管機(jī)的重大技術(shù)進(jìn)步情況和少機(jī)架限動(dòng)芯棒連軋管機(jī)的特點(diǎn)。對(duì)正在研究的三輥可調(diào)式連軋管機(jī)(PQF)也作了較詳細(xì)的介紹。Abstract: Thanks to the continuous development for nearly twenty years, the process technology of retained-mandrel MPM has been so sound that it has become one of the major seamless steel tube mills being used nowadays. Briefly introduced in this paper are the significant progress made in technical development of retained-mandrel MPM and the characteristics of the retained-mandrel MPM with fewer stands. Also describd here is details about research involving the three-roll adjustable MPM (PQF).
