20世(shi)紀50年代(dai)以(yi)來，由于傳動(dong)(dong)技(ji)(ji)術(shu)(shu)和電(dian)氣控制(zhi)技(ji)(ji)術(shu)(shu)的(de)(de)突破，連軋(ya)(ya)管(guan)生產(chan)(chan)技(ji)(ji)術(shu)(shu)得(de)到(dao)了長足的(de)(de)發展。芯(xin)棒(bang)(bang)(bang)運行(xing)方(fang)式(shi)從浮動(dong)(dong)式(shi)芯(xin)棒(bang)(bang)(bang)軋(ya)(ya)機(ji)(ji)(ji)(ji)(ji)(ji)到(dao)限(xian)動(dong)(dong)式(shi)芯(xin)棒(bang)(bang)(bang)軋(ya)(ya)機(ji)(ji)(ji)(ji)(ji)(ji)以(yi)及半浮動(dong)(dong)式(shi)芯(xin)棒(bang)(bang)(bang)軋(ya)(ya)機(ji)(ji)(ji)(ji)(ji)(ji)，機(ji)(ji)(ji)(ji)(ji)(ji)架數從9～7架減(jian)少到(dao)6～5架，軋(ya)(ya)制(zhi)工藝從兩輥變為三輥，80年代(dai)后(hou)大口徑、少機(ji)(ji)(ji)(ji)(ji)(ji)架限(xian)動(dong)(dong)芯(xin)棒(bang)(bang)(bang)連軋(ya)(ya)管(guan)技(ji)(ji)術(shu)(shu)的(de)(de)出現，使得(de)鋼管(guan)連軋(ya)(ya)更是爐火(huo)純(chun)青(qing)。生產(chan)(chan)過程的(de)(de)操(cao)作(zuo)方(fang)式(shi)由手動(dong)(dong)到(dao)區域自動(dong)(dong)化(hua)到(dao)整條線(xian)由CPU、PLC控制(zhi)的(de)(de)全自動(dong)(dong)化(hua)運行(xing)方(fang)式(shi)，采用了液壓(ya)小(xiao)倉(cang)控制(zhi)技(ji)(ji)術(shu)(shu)，配套了工藝控制(zhi)軟件技(ji)(ji)術(shu)(shu)，連軋(ya)(ya)管(guan)機(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)整體裝(zhuang)備水平(ping)有了很大的(de)(de)改(gai)變。與其(qi)他機(ji)(ji)(ji)(ji)(ji)(ji)型相(xiang)比連軋(ya)(ya)管(guan)機(ji)(ji)(ji)(ji)(ji)(ji)以(yi)優質、高產(chan)(chan)、高效率、低消耗(hao)等特點，成為世(shi)界(jie)無縫鋼管(guan)主要生產(chan)(chan)企(qi)業的(de)(de)首選機(ji)(ji)(ji)(ji)(ji)(ji)型。

  經過(guo)30余(yu)年的(de)(de)(de)消化、吸收、再創新，國產連(lian)(lian)(lian)(lian)軋(ya)(ya)(ya)管機(ji)已基本達(da)到國際先進水平。太原重工(gong)(gong)繼(ji)與(yu)國外聯合(he)設計寶鋼ф140機(ji)組(zu)(zu)(zu)(zu)(zu)和天(tian)津φ250機(ji)組(zu)(zu)(zu)(zu)(zu)后(hou)，又陸續制(zhi)造(zao)了多套Φ159mm、φ180mm三輥連(lian)(lian)(lian)(lian)軋(ya)(ya)(ya)機(ji)組(zu)(zu)(zu)(zu)(zu)。太原通澤重工(gong)(gong)繼(ji)2006年建(jian)設了φ250mm 五機(ji)架限(xian)動芯棒連(lian)(lian)(lian)(lian)軋(ya)(ya)(ya)機(ji)后(hou)，又陸續制(zhi)造(zao)了φ114mm二輥連(lian)(lian)(lian)(lian)軋(ya)(ya)(ya)機(ji)組(zu)(zu)(zu)(zu)(zu)和ф159mm、Φ273mm、Φ356mm等(deng)多個規格三輥連(lian)(lian)(lian)(lian)軋(ya)(ya)(ya)機(ji)組(zu)(zu)(zu)(zu)(zu)；中(zhong)冶賽迪分別于2012年、2017年自主(zhu)集成(cheng)建(jian)設了φ76mm四機(ji)架、ф89mm六機(ji)架三輥連(lian)(lian)(lian)(lian)軋(ya)(ya)(ya)機(ji)組(zu)(zu)(zu)(zu)(zu)和正在建(jian)設的(de)(de)(de)φ159mm三輥連(lian)(lian)(lian)(lian)軋(ya)(ya)(ya)管機(ji)組(zu)(zu)(zu)(zu)(zu)。以(yi)上機(ji)組(zu)(zu)(zu)(zu)(zu)的(de)(de)(de)設備的(de)(de)(de)控(kong)制(zhi)精度逐步(bu)提高，代表了我(wo)國軋(ya)(ya)(ya)管設備制(zhi)造(zao)和工(gong)(gong)藝水平。國產的(de)(de)(de)連(lian)(lian)(lian)(lian)軋(ya)(ya)(ya)管機(ji)組(zu)(zu)(zu)(zu)(zu)的(de)(de)(de)建(jian)設推動了中(zhong)國鋼管工(gong)(gong)業的(de)(de)(de)高速發展(zhan)。截至2018年，國內共有(you)連(lian)(lian)(lian)(lian)軋(ya)(ya)(ya)管機(ji)組(zu)(zu)(zu)(zu)(zu)46套（含在建(jian)機(ji)組(zu)(zu)(zu)(zu)(zu)）。
