　　由(you)于汽車用(yong)(yong)(yong)材(cai)的(de)(de)(de)特殊(shu)性(xing)(xing)，要(yao)(yao)(yao)求(qiu)所用(yong)(yong)(yong)鋼(gang)(gang)(gang)管(guan)(guan)(guan)外型美觀(guan)、重量輕、行駛安全(quan)、平穩可靠。為確保45#精密(mi)(mi)光(guang)亮管(guan)(guan)(guan)的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)時效，要(yao)(yao)(yao)求(qiu)鋼(gang)(gang)(gang)管(guan)(guan)(guan)用(yong)(yong)(yong)材(cai)質具有良好(hao)的(de)(de)(de)耐腐蝕性(xing)(xing)，具有一定的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽(shou)命，所以(yi)根據使(shi)(shi)用(yong)(yong)(yong)部位的(de)(de)(de)不同，分(fen)別(bie)對45#精密(mi)(mi)光(guang)亮管(guan)(guan)(guan)的(de)(de)(de)材(cai)質、尺寸精度(du)、機械性(xing)(xing)能(neng)、工藝性(xing)(xing)能(neng)及表面質量等各方面都有嚴格的(de)(de)(de)要(yao)(yao)(yao)求(qiu)。部分(fen)特殊(shu)產品還(huan)對鋼(gang)(gang)(gang)管(guan)(guan)(guan)有耐磨性(xing)(xing)、--性(xing)(xing)能(neng)、焊(han)接性(xing)(xing)能(neng)等相應要(yao)(yao)(yao)求(qiu)。許多情(qing)況下鋼(gang)(gang)(gang)管(guan)(guan)(guan)需要(yao)(yao)(yao)有良好(hao)的(de)(de)(de)焊(han)接性(xing)(xing)能(neng)，45#精密(mi)(mi)光(guang)亮管(guan)(guan)(guan)，而且(qie)要(yao)(yao)(yao)有很好(hao)的(de)(de)(de)再(zai)加工性(xing)(xing)能(neng)和熱(re)處(chu)理(li)性(xing)(xing)能(neng)。部分(fen)最終零部件(jian)有表面鍍、涂層要(yao)(yao)(yao)求(qiu)的(de)(de)(de)鋼(gang)(gang)(gang)管(guan)(guan)(guan)，要(yao)(yao)(yao)求(qiu)光(guang)亮熱(re)處(chu)理(li)狀態

　　45#精密光亮管屬于高級機械結構用管，按其生產方式可以分為三類：一種是45#精密光亮管(拔制或軋制);另(ling)一(yi)種是高精度焊接(jie)(jie)鋼管(要求去(qu)內毛刺(ci));再有(you)一(yi)種是將去(qu)除(chu)內毛刺(ci)的焊接(jie)(jie)鋼管作為管坯繼續冷(leng)加工(gong)(或最(zui)后(hou)熱處理)后(hou)使用

　　45#精密光亮管的生產工藝

　　45#精密光亮管，因其產(chan)(chan)(chan)品特(te)殊性，具有(you)較高(gao)的產(chan)(chan)(chan)品技(ji)術含量，需(xu)要采用多種生產(chan)(chan)(chan)方式(shi)。部(bu)(bu)分(fen)產(chan)(chan)(chan)品需(xu)要集“焊—拔—軋(ya)(ya)”結合的生產(chan)(chan)(chan)方式(shi)，才(cai)能完(wan)全滿足使用要求(qiu)。對于一些需(xu)要開(kai)發綜(zong)合生產(chan)(chan)(chan)技(ji)術的產(chan)(chan)(chan)品，國內(nei)(nei)部(bu)(bu)分(fen)生產(chan)(chan)(chan)企業進行過一些試驗研究工(gong)(gong)作，積累(lei)有(you)一定的生產(chan)(chan)(chan)技(ji)術經驗。但需(xu)要在(zai)管(guan)坯質(zhi)(zhi)量的控制選定、焊管(guan)成型工(gong)(gong)藝、焊縫熱處(chu)理、去(qu)內(nei)(nei)毛(mao)刺技(ji)術、冷拔(軋(ya)(ya))聯合工(gong)(gong)藝、成品無(wu)氧化(光(guang)亮)熱處(chu)理、高(gao)精(jing)度(薄(bo)壁)鋼管(guan)精(jing)整、檢測等關鍵技(ji)術上實現(xian)有(you)效(xiao)配套，才(cai)能完(wan)全確保45#精(jing)密光(guang)亮管(guan)生產(chan)(chan)(chan)的技(ji)術質(zhi)(zhi)量要求(qiu)。
