至德鋼業不銹鋼無縫鋼管制造工藝介紹
不(bu)銹鋼無(wu)(wu)縫(feng)(feng)鋼管(guan)(guan)因其制造工藝(yi)不(bu)同，又(you)分為熱(re)軋(ya)(ya)（擠壓）不(bu)銹鋼無(wu)(wu)縫(feng)(feng)管(guan)(guan)和冷拔(ba)（軋(ya)(ya)）不(bu)銹鋼無(wu)(wu)縫(feng)(feng)管(guan)(guan)兩(liang)種。冷拔(ba)（軋(ya)(ya)）管(guan)(guan)又(you)分為圓形管(guan)(guan)和異形管(guan)(guan)兩(liang)種。 工藝(yi)流程：①.熱(re)軋(ya)(ya)（擠壓）無(wu)(wu)縫(feng)(feng)鋼管(guan)(guan)生產(chan)工藝(yi)：生產(chan)圓管(guan)(guan)坯→加(jia)熱(re)→穿孔→三輥斜軋(ya)(ya)、連軋(ya)(ya)或擠壓→脫管(guan)(guan)→定徑（或減徑）→冷卻→矯...
