    CPE頂管機(jī)組熱軋T91無(wú)縫鋼管的工藝研究

    Process Study of CPE Mill for Hot-rolling T91 Seamless Steel Tube

    • 摘要: 介紹CPE頂管機(jī)組生產(chǎn)T91無(wú)縫鋼管的工藝流程，分析生產(chǎn)中可能出現(xiàn)的問(wèn)題，評(píng)定生產(chǎn)的Φ60 mm×7 mm規(guī)格T91無(wú)縫鋼管的質(zhì)量。生產(chǎn)實(shí)踐表明：采用合理的加熱制度及可靠的穿孔工藝參數(shù)，通過(guò)頂管及張力減徑延伸，完全可以實(shí)現(xiàn)T91無(wú)縫鋼管的穩(wěn)定生產(chǎn)。CPE頂管機(jī)組熱軋T91無(wú)縫鋼管時(shí)，應(yīng)重點(diǎn)對(duì)加熱制度、穿孔工藝進(jìn)行控制。

       

      Abstract: The producing process of T91 seamless steel tube by CPE mill is introduced.Problems that may occur during the process are analyzed, and the quality of the produced Φ60 mm×7 mm T91 seamless steel tubes are evluated.The practical production shows that by adopting reasonalble heating schedule and reliable piercing parameters, and through elongating on the push-bench and the stretch reducing mill, a stable production of T91 seamless steel tube can be realized.For producing T91 seamless steel tube by CPE mill, the heating schedule and the piercing process shall be well controlled.
