 生產改組前鋼(gang)(gang)管公司的(de)(de)(de)煉鋼(gang)(gang)廠由于生產率低(di)，競爭(zheng)能力很差；MPM軋管廠對于直徑大于179mm的(de)(de)(de)管子來說(shuo)(shuo)生產率是很高(gao)的(de)(de)(de)，但設備利用(yong)率低(di)于70%;周(zhou)期軋管廠，對大直徑鋼(gang)(gang)管的(de)(de)(de)生產來說(shuo)(shuo)，生產能力是足夠的(de)(de)(de)，但由于采用(yong)鋼(gang)(gang)錠，原材料成本高(gao)。工(gong)藝陳舊，質量水平低(di)下。

 根(gen)據上述情況，為了(le)提(ti)高(gao)競爭(zheng)能(neng)力，生產系(xi)統重組(zu)的(de)總(zong)目標是：提(ti)高(gao)MPM軋管廠的(de)設備利用率；由(you)于擴(kuo)徑管坯單重提(ti)高(gao)，使MPM軋機按新的(de)產品大綱生產，提(ti)高(gao)其產量水平；用連鑄圓坯取代鋼錠。

 其具體(ti)做(zuo)法是(shi)：對煉鋼(gang)(gang)廠而言，45噸煉鋼(gang)(gang)爐停產，為(wei)了(le)提(ti)(ti)高管(guan)(guan)(guan)坯自給能力要(yao)提(ti)(ti)高煉鋼(gang)(gang)能力，以(yi)提(ti)(ti)供(gong)本廠所需的(de)全部連鑄(zhu)圓坯；對于(yu)ф406mm(16英(ying)寸）以(yi)上(shang)不銹鋼(gang)(gang)管(guan)(guan)(guan)的(de)產生而言，拆除周期軋管(guan)(guan)(guan)機，設置擴(kuo)(kuo)管(guan)(guan)(guan)機和(he)均整機，其母(mu)體(ti)管(guan)(guan)(guan)由(you)MPM軋機生產。在(zai)1995年3月(yue)舉行的(de)費城國際鋼(gang)(gang)管(guan)(guan)(guan)會議上(shang)INNSE和(he)Dalmine兩公(gong)(gong)司(si)聯(lian)合宣(xuan)讀了(le)關于(yu)斜(xie)軋擴(kuo)(kuo)徑工(gong)(gong)藝(yi)及其應用實例的(de)論文，接(jie)著(zhu)INNSE公(gong)(gong)司(si)又在(zai)1996年第1期的(de)《Tube &Pipe Technology》雜志上(shang)發表題為(wei)“Quality Improvement and production Flexibility ob-tained through Hot Rotary Expansion of Tubes”一文，其內容主(zhu)要(yao)是(shi)講斜(xie)軋擴(kuo)(kuo)徑工(gong)(gong)藝(yi)技術，根據達爾明公(gong)(gong)司(si)新的(de)斜(xie)軋擴(kuo)(kuo)徑機投產的(de)經驗，INNSE將這種工(gong)(gong)藝(yi)正式(shi)稱作NRE工(gong)(gong)藝(yi)，即“New Rotary Expanding(technology)。
