 生產(chan)(chan)改組前(qian)鋼管公司的(de)煉鋼廠(chang)由(you)(you)于(yu)生產(chan)(chan)率(lv)(lv)低(di)(di)，競爭(zheng)能(neng)力(li)很差(cha)；MPM軋(ya)管廠(chang)對(dui)于(yu)直(zhi)徑(jing)大于(yu)179mm的(de)管子來說(shuo)生產(chan)(chan)率(lv)(lv)是很高的(de)，但(dan)(dan)設備利用率(lv)(lv)低(di)(di)于(yu)70%;周期軋(ya)管廠(chang)，對(dui)大直(zhi)徑(jing)鋼管的(de)生產(chan)(chan)來說(shuo)，生產(chan)(chan)能(neng)力(li)是足夠(gou)的(de)，但(dan)(dan)由(you)(you)于(yu)采用鋼錠，原材料成本(ben)高。工藝陳舊(jiu)，質(zhi)量水平(ping)低(di)(di)下。

 根據上(shang)述情況，為了提高競爭能力，生產(chan)(chan)系統重組的總目標是：提高MPM軋(ya)(ya)管廠(chang)的設備利用(yong)率；由于擴徑(jing)管坯單重提高，使(shi)MPM軋(ya)(ya)機按新(xin)的產(chan)(chan)品大(da)綱生產(chan)(chan)，提高其產(chan)(chan)量水平；用(yong)連鑄圓(yuan)坯取代(dai)鋼(gang)錠。

 其具體做法(fa)是(shi)：對煉(lian)(lian)鋼(gang)廠(chang)而言，45噸(dun)煉(lian)(lian)鋼(gang)爐停產(chan)，為(wei)了提(ti)高(gao)管坯(pi)自(zi)給能力要提(ti)高(gao)煉(lian)(lian)鋼(gang)能力，以提(ti)供本廠(chang)所需的全部連(lian)鑄圓(yuan)坯(pi)；對于ф406mm(16英寸）以上(shang)不銹(xiu)鋼(gang)管的產(chan)生而言，拆除周期軋(ya)(ya)管機(ji)，設置擴(kuo)管機(ji)和均整機(ji)，其母體管由MPM軋(ya)(ya)機(ji)生產(chan)。在(zai)1995年3月舉行的費(fei)城國際(ji)鋼(gang)管會議上(shang)INNSE和Dalmine兩公司(si)(si)聯合(he)宣讀(du)了關于斜(xie)軋(ya)(ya)擴(kuo)徑(jing)工(gong)藝(yi)及其應用實例的論文(wen)，接著INNSE公司(si)(si)又在(zai)1996年第(di)1期的《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(wen)，其內(nei)容主(zhu)要是(shi)講(jiang)斜(xie)軋(ya)(ya)擴(kuo)徑(jing)工(gong)藝(yi)技術，根據達爾明公司(si)(si)新的斜(xie)軋(ya)(ya)擴(kuo)徑(jing)機(ji)投產(chan)的經驗，INNSE將這種工(gong)藝(yi)正(zheng)式稱作NRE工(gong)藝(yi)，即“New Rotary Expanding(technology)。
