浙江至德鋼業穿孔+(冷軋、冷拔)不銹鋼無縫管生產工藝介紹
采用(yong)二輥斜(xie)軋穿孔生產不(bu)銹(xiu)鋼毛管,是(shi)國(guo)外20世紀30年代所(suo)采用(yong)過的方法。我國(guo)從(cong)60年代開始,采用(yong)二輥斜(xie)軋穿孔+冷軋/拔(ba)工(gong)(gong)藝(yi)生產不(bu)銹(xiu)鋼管,并一(yi)直(zhi)延續(xu)到(dao)今天。這種(zhong)工(gong)(gong)藝(yi)已成為我國(guo)不(bu)銹(xiu)鋼無縫管生產的傳統工(gong)(gong)藝(yi)。采用(yong)這種(zhong)工(gong)(gong)藝(yi)開發不(bu)銹(xiu)鋼管品種(zhong)以及工(gong)(gong)藝(yi)優化的研究一(yi)直(zhi)沒有中(zhong)斷,并積累了...
