 生產(chan)(chan)改組前鋼(gang)管(guan)公司的(de)(de)煉(lian)鋼(gang)廠由于(yu)生產(chan)(chan)率(lv)(lv)低，競爭能(neng)力很(hen)差；MPM軋管(guan)廠對(dui)于(yu)直徑(jing)大于(yu)179mm的(de)(de)管(guan)子來說(shuo)生產(chan)(chan)率(lv)(lv)是很(hen)高的(de)(de)，但設備(bei)利(li)用率(lv)(lv)低于(yu)70%;周期軋管(guan)廠，對(dui)大直徑(jing)鋼(gang)管(guan)的(de)(de)生產(chan)(chan)來說(shuo)，生產(chan)(chan)能(neng)力是足夠的(de)(de)，但由于(yu)采(cai)用鋼(gang)錠，原(yuan)材料成(cheng)本(ben)高。工(gong)藝陳(chen)舊，質量水平低下。

 根據上述(shu)情況，為了提(ti)(ti)高(gao)競爭能力(li)，生(sheng)產系統重組的(de)(de)總目標是：提(ti)(ti)高(gao)MPM軋管廠的(de)(de)設備利用率；由于擴(kuo)徑管坯單(dan)重提(ti)(ti)高(gao)，使MPM軋機按新的(de)(de)產品(pin)大綱生(sheng)產，提(ti)(ti)高(gao)其產量水平；用連鑄(zhu)圓坯取(qu)代鋼錠。

 其具體做法是：對煉(lian)鋼(gang)廠(chang)而言，45噸煉(lian)鋼(gang)爐停產，為了提(ti)高(gao)管坯自給能力要(yao)提(ti)高(gao)煉(lian)鋼(gang)能力，以提(ti)供本廠(chang)所(suo)需的(de)全部連(lian)鑄圓坯；對于ф406mm(16英(ying)寸）以上(shang)不銹鋼(gang)管的(de)產生(sheng)(sheng)而言，拆除周期(qi)(qi)軋管機，設置擴(kuo)管機和(he)均整機，其母體管由(you)MPM軋機生(sheng)(sheng)產。在(zai)1995年3月舉行的(de)費城(cheng)國際鋼(gang)管會議上(shang)INNSE和(he)Dalmine兩公司(si)聯合宣讀了關于斜軋擴(kuo)徑(jing)工(gong)藝及其應用實例的(de)論(lun)文(wen)，接(jie)著(zhu)INNSE公司(si)又在(zai)1996年第1期(qi)(qi)的(de)《Tube &Pipe Technology》雜志上(shang)發表題為“Quality Improvement and production Flexibility ob-tained through Hot Rotary Expansion of Tubes”一文(wen)，其內容主(zhu)要(yao)是講斜軋擴(kuo)徑(jing)工(gong)藝技術(shu)，根據達爾明(ming)公司(si)新的(de)斜軋擴(kuo)徑(jing)機投產的(de)經驗，INNSE將這種工(gong)藝正式稱作NRE工(gong)藝，即“New Rotary Expanding(technology)。
