 生產(chan)改組(zu)前鋼(gang)管(guan)(guan)公司(si)的(de)(de)煉(lian)鋼(gang)廠由(you)于生產(chan)率低(di)，競爭能(neng)力(li)很(hen)差；MPM軋管(guan)(guan)廠對于直(zhi)徑大于179mm的(de)(de)管(guan)(guan)子來說生產(chan)率是(shi)很(hen)高的(de)(de)，但(dan)設備利用(yong)率低(di)于70%;周期軋管(guan)(guan)廠，對大直(zhi)徑鋼(gang)管(guan)(guan)的(de)(de)生產(chan)來說，生產(chan)能(neng)力(li)是(shi)足(zu)夠(gou)的(de)(de)，但(dan)由(you)于采用(yong)鋼(gang)錠(ding)，原材料成(cheng)本高。工藝陳舊，質量水平低(di)下。

 根據上(shang)述情況(kuang)，為(wei)了提(ti)高競爭(zheng)能力，生產系統重組(zu)的總目標(biao)是：提(ti)高MPM軋管(guan)廠的設備利用率；由于擴徑管(guan)坯(pi)單重提(ti)高，使MPM軋機按新的產品大綱生產，提(ti)高其產量水平；用連鑄圓(yuan)坯(pi)取代鋼錠(ding)。

 其(qi)具體做法是：對煉鋼(gang)(gang)廠而言，45噸(dun)煉鋼(gang)(gang)爐停產，為(wei)了提高管(guan)坯(pi)自給能(neng)力要提高煉鋼(gang)(gang)能(neng)力，以提供本(ben)廠所需的全(quan)部連(lian)鑄圓(yuan)坯(pi)；對于ф406mm(16英寸）以上不銹鋼(gang)(gang)管(guan)的產生而言，拆除周期軋管(guan)機(ji)，設置(zhi)擴管(guan)機(ji)和(he)均整機(ji)，其(qi)母體管(guan)由MPM軋機(ji)生產。在1995年3月(yue)舉行的費城國際鋼(gang)(gang)管(guan)會(hui)議(yi)上INNSE和(he)Dalmine兩(liang)公(gong)(gong)司(si)聯合宣讀了關于斜(xie)軋擴徑工(gong)藝及(ji)其(qi)應(ying)用(yong)實例的論文，接著INNSE公(gong)(gong)司(si)又(you)在1996年第1期的《Tube &Pipe Technology》雜(za)志上發表(biao)題為(wei)“Quality Improvement and production Flexibility ob-tained through Hot Rotary Expansion of Tubes”一(yi)文，其(qi)內容主要是講(jiang)斜(xie)軋擴徑工(gong)藝技術，根據達爾明公(gong)(gong)司(si)新(xin)的斜(xie)軋擴徑機(ji)投(tou)產的經驗，INNSE將(jiang)這(zhe)種工(gong)藝正(zheng)式(shi)稱(cheng)作NRE工(gong)藝，即“New Rotary Expanding(technology)。
