    Practice of Production Technology for ZT640 Economical Heavy/medium-walled Seamless Steel Tube for Geological Drilling Service

    • 摘要: 用37Mn5鋼生產(chǎn)經(jīng)濟(jì)型中厚壁ZT640地質(zhì)鉆探用無縫鋼管。介紹ZT640無縫鋼管的生產(chǎn)工藝、關(guān)鍵控制技術(shù)和質(zhì)量情況，以及37Mn5中厚壁無縫鋼管淬火裂紋的控制措施。分析認(rèn)為：通過“轉(zhuǎn)爐煉鋼+LF精煉+方坯連鑄+軋制圓坯+連軋+調(diào)質(zhì)”工藝生產(chǎn)的中厚壁地質(zhì)鉆探用ZT640調(diào)質(zhì)無縫鋼管，其各項(xiàng)性能指標(biāo)和尺寸精度等完全滿足技術(shù)要求，說明生產(chǎn)工藝可行；用37Mn5鋼代替35CrMo鋼種，可實(shí)現(xiàn)經(jīng)濟(jì)型生產(chǎn)的目的。

       

      Abstract: Described here in the paper is how to use the 37Mn5 steel to produce the ZT640 economical heavy/mediumwalled seamless steel tube for geological drilling service,involving the manufacturing process,the key control techniques and the quality status,and the control measures as taken to prevent the quench-caused crack of the 37Mn5 heavy/medium-walled seamless steel tube.It is regarded via the analysis that the ZT640 quench and tempered heavy/mediumwalled seamless steel tube for geological drilling service as produced by means of the process of“Converter+LF+Square CC+Round rolling+PQFpipe-rolling+Quenching & tempering”hasall of itstechnical indexes and dimensional tolerances fully conform to applicable technical requirements,which means that the manufacturing process as employed is quite practical.And it is finally concluded that substituting the 37Mn5 steel for the 35CrMo steel is able to bring about the economical production of the said product.
