不(bu)銹(xiu)鋼(gang)(gang)管(guan)是一種(zhong)用穿孔法加工的中空焊接鋼(gang)(gang)管(guan)。溫州不(bu)銹(xiu)鋼(gang)(gang)管(guan)廠家通常(chang),不(bu)銹(xiu)鋼(gang)(gang)管(guan)的外徑范(fan)圍為0.1毫(hao)米(mi)至1425毫(hao)米(mi),壁厚范(fan)圍為0.01-200毫(hao)米(mi)至200毫(hao)米(mi)。不(bu)銹(xiu)鋼(gang)(gang)管(guan)分為從鋼(gang)(gang)到(dao)最終成(cheng)型的三個過(guo)程:
第(di)一(yi)階段在軋鋼廠完成,主要(yao)通(tong)過(guo)鑄造生產環形(xing)實心管(guan)坯。
第二階(jie)段在軋(ya)(ya)(ya)管(guan)(guan)廠完(wan)成。將(jiang)軋(ya)(ya)(ya)鋼(gang)(gang)不銹鋼(gang)(gang)管(guan)(guan)廠家廠獲得的(de)(de)管(guan)(guan)坯(pi)切割(ge)成塊,然(ran)后(hou)(hou)轉(zhuan)移到(dao)熔化(hua)爐(lu)中加熱,并(bing)在出爐(lu)后(hou)(hou)用(yong)壓力穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong)器穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong)。常見的(de)(de)穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong)器是錐形輥穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong)器。用(yong)該穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong)器加工的(de)(de)產(chan)品質(zhi)量好,直徑(jing)膨脹大。同時(shi),生產(chan)效率相(xiang)對(dui)較高。穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong)時(shi),穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong)毛細(xi)管(guan)(guan)的(de)(de)壁厚必(bi)須均勻,橄(gan)欖(lan)環度小,幾何尺寸(cun)精度高。其(qi)次,毛細(xi)管(guan)(guan)的(de)(de)內表面(mian)和(he)外(wai)表面(mian)應(ying)(ying)該更(geng)光滑(hua),并(bing)且(qie)沒有諸如結(jie)疤、折(zhe)疊和(he)開(kai)裂等缺(que)陷。最后(hou)(hou),必(bi)須有相(xiang)應(ying)(ying)的(de)(de)穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong)速度和(he)軋(ya)(ya)(ya)制(zhi)周(zhou)期(qi)來適應(ying)(ying)機組的(de)(de)生產(chan)節奏,使鋼(gang)(gang)坯(pi)的(de)(de)最終軋(ya)(ya)(ya)制(zhi)溫(wen)度能夠滿足軋(ya)(ya)(ya)管(guan)(guan)機的(de)(de)要求。穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong)后(hou)(hou),管(guan)(guan)坯(pi)面(mian)臨熱軋(ya)(ya)(ya)和(he)冷軋(ya)(ya)(ya)兩種軋(ya)(ya)(ya)制(zhi)方法。熱軋(ya)(ya)(ya)是根據后(hou)(hou)續(xu)工序的(de)(de)縮徑(jing)母量和(he)經驗公式(shi)確定鋼(gang)(gang)管(guan)(guan)的(de)(de)壁厚,然(ran)后(hou)(hou)通過連續(xu)軋(ya)(ya)(ya)制(zhi)將(jiang)鋼(gang)(gang)坯(pi)轉(zhuan)變成壁厚接(jie)近(jin)成品的(de)(de)鋼(gang)(gang)坯(pi),然(ran)后(hou)(hou)將(jiang)鋼(gang)(gang)坯(pi)高速旋轉(zhuan)到(dao)定徑(jing)機中,得到(dao)所需的(de)(de)鋼(gang)(gang)坯(pi)。冷軋(ya)(ya)(ya)后(hou)(hou)對(dui)管(guan)(guan)坯(pi)進行(xing)穿(chuan)(chuan)(chuan)孔(kong)(kong)(kong),坯(pi)體進行(xing)鐓頭(tou)退火,用(yong)特殊酸性液體酸洗(xi),經多次冷軋(ya)(ya)(ya)形成坯(pi)體。
第(di)三階(jie)段在制管(guan)(guan)廠完成(cheng)。制管(guan)(guan)廠的(de)(de)后(hou)續(xu)處理(li)分為兩部分:熱處理(li)和管(guan)(guan)道加(jia)工。熱處理(li)是(shi)對坯管(guan)(guan)進(jin)(jin)行(xing)相應的(de)(de)熱處理(li),然后(hou)矯(jiao)直(zhi),然后(hou)對不銹鋼管(guan)(guan)進(jin)(jin)行(xing)裂紋、氣(qi)泡等問題的(de)(de)無損檢測。管(guan)(guan)材加(jia)工是(shi)對坯管(guan)(guan)進(jin)(jin)行(xing)相應的(de)(de)機械加(jia)工,包括攻絲、通徑、涂(tu)漆等工序。熱處理(li)和管(guan)(guan)材加(jia)工完成(cheng)后(hou),最終(zhong)得到(dao)成(cheng)品鋼管(guan)(guan)。
