 生(sheng)(sheng)產改組(zu)前(qian)鋼(gang)管(guan)(guan)公司的煉(lian)鋼(gang)廠由(you)(you)于(yu)(yu)(yu)生(sheng)(sheng)產率(lv)(lv)低(di)，競爭能(neng)力很差；MPM軋管(guan)(guan)廠對于(yu)(yu)(yu)直徑(jing)大于(yu)(yu)(yu)179mm的管(guan)(guan)子來(lai)說生(sheng)(sheng)產率(lv)(lv)是很高的，但(dan)設備利(li)用(yong)率(lv)(lv)低(di)于(yu)(yu)(yu)70%;周期軋管(guan)(guan)廠，對大直徑(jing)鋼(gang)管(guan)(guan)的生(sheng)(sheng)產來(lai)說，生(sheng)(sheng)產能(neng)力是足夠的，但(dan)由(you)(you)于(yu)(yu)(yu)采用(yong)鋼(gang)錠(ding)，原材(cai)料成本高。工(gong)藝陳舊，質量水(shui)平低(di)下。

 根據上述(shu)情(qing)況(kuang)，為(wei)了提高競爭能力，生產系統重組的總目標是(shi)：提高MPM軋(ya)管(guan)廠(chang)的設備(bei)利用率；由于擴徑管(guan)坯單重提高，使MPM軋(ya)機按(an)新的產品大綱生產，提高其產量水平；用連鑄圓坯取代鋼錠(ding)。

 其具體(ti)(ti)做法(fa)是：對煉鋼(gang)(gang)廠(chang)而(er)言，45噸(dun)煉鋼(gang)(gang)爐停產(chan)(chan)，為了(le)提(ti)高管(guan)坯自給能(neng)力要提(ti)高煉鋼(gang)(gang)能(neng)力，以提(ti)供本廠(chang)所需的全部連(lian)鑄圓坯；對于(yu)ф406mm(16英(ying)寸(cun)）以上(shang)(shang)不銹鋼(gang)(gang)管(guan)的產(chan)(chan)生(sheng)而(er)言，拆除周期軋(ya)管(guan)機，設置擴管(guan)機和(he)均整機，其母體(ti)(ti)管(guan)由(you)MPM軋(ya)機生(sheng)產(chan)(chan)。在1995年3月舉(ju)行(xing)的費城國際(ji)鋼(gang)(gang)管(guan)會議上(shang)(shang)INNSE和(he)Dalmine兩公(gong)司聯合宣(xuan)讀了(le)關于(yu)斜(xie)軋(ya)擴徑工藝及(ji)其應(ying)用實例的論(lun)文(wen)，接著INNSE公(gong)司又在1996年第(di)1期的《Tube &Pipe Technology》雜(za)志上(shang)(shang)發表題(ti)為“Quality Improvement and production Flexibility ob-tained through Hot Rotary Expansion of Tubes”一文(wen)，其內容(rong)主(zhu)要是講斜(xie)軋(ya)擴徑工藝技術，根據達爾(er)明公(gong)司新的斜(xie)軋(ya)擴徑機投產(chan)(chan)的經驗，INNSE將這種工藝正式稱作NRE工藝，即(ji)“New Rotary Expanding(technology)。
