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(cai)用(yong)(yong)二(er)輥(gun)斜(xie)軋穿孔生(sheng)產不(bu)銹(xiu)鋼毛(mao)管，是國外(wai)20世紀30年代所采(cai)用(yong)(yong)過(guo)的(de)方法(fa)。我(wo)國從60年代開(kai)(kai)始，采(cai)用(yong)(yong)二(er)輥(gun)斜(xie)軋穿孔＋冷軋／拔工(gong)(gong)(gong)藝(yi)(yi)生(sheng)產不(bu)銹(xiu)鋼管，并一直(zhi)延(yan)續(xu)到今(jin)天。這(zhe)種工(gong)(gong)(gong)藝(yi)(yi)已成(cheng)為我(wo)國不(bu)銹(xiu)鋼無縫管生(sheng)產的(de)傳統工(gong)(gong)(gong)藝(yi)(yi)。采(cai)用(yong)(yong)這(zhe)種工(gong)(gong)(gong)藝(yi)(yi)開(kai)(kai)發不(bu)銹(xiu)鋼管品種以及(ji)工(gong)(gong)(gong)藝(yi)(yi)優化的(de)研究一直(zhi)沒(mei)有中斷，并積累了...
