至德鋼業不銹鋼無縫鋼管制造工藝介紹
不銹鋼無(wu)(wu)(wu)(wu)縫鋼管(guan)(guan)因其制造工(gong)藝(yi)不同，又分(fen)(fen)為熱(re)軋(ya)(ya)（擠壓(ya)）不銹鋼無(wu)(wu)(wu)(wu)縫管(guan)(guan)和冷(leng)(leng)拔(ba)（軋(ya)(ya)）不銹鋼無(wu)(wu)(wu)(wu)縫管(guan)(guan)兩(liang)種。冷(leng)(leng)拔(ba)（軋(ya)(ya)）管(guan)(guan)又分(fen)(fen)為圓形管(guan)(guan)和異形管(guan)(guan)兩(liang)種。 工(gong)藝(yi)流程：①.熱(re)軋(ya)(ya)（擠壓(ya)）無(wu)(wu)(wu)(wu)縫鋼管(guan)(guan)生產(chan)工(gong)藝(yi)：生產(chan)圓管(guan)(guan)坯→加熱(re)→穿孔→三輥斜軋(ya)(ya)、連軋(ya)(ya)或擠壓(ya)→脫(tuo)管(guan)(guan)→定徑（或減徑）→冷(leng)(leng)卻→矯...
