碳鋼管制備方法編輯
碳鋼管的原料是圓管坯,圓管胚要經(jīng)過(guò)切割機(jī)的切割加工成長(zhǎng)度約為1米的坯料,并經(jīng)傳送帶送到熔爐內(nèi)加熱。鋼坯被送入熔爐內(nèi)加熱,溫度大約為1200攝氏度。燃料為氫氣或乙炔。爐內(nèi)溫度控制是關(guān)鍵性的問(wèn)題.圓管坯出爐后要經(jīng)過(guò)壓力穿孔機(jī)進(jìn)行穿空。一般較常見(jiàn)的穿孔機(jī)是錐形輥穿孔機(jī),這種穿孔機(jī)生產(chǎn)效率高,產(chǎn)品質(zhì)量好,穿孔擴(kuò)徑量大,可穿多種鋼種。穿孔后,圓管坯就先后被三輥斜軋、連軋或擠壓。擠壓后要脫管定徑。定徑機(jī)通過(guò)錐形鉆頭高速旋轉(zhuǎn)入鋼胚打孔,形成鋼管。鋼管內(nèi)徑由定徑機(jī)鉆頭的外徑長(zhǎng)度來(lái)確定。鋼管經(jīng)定徑后,進(jìn)入冷卻塔中,通過(guò)噴水冷卻,鋼管經(jīng)冷卻后,就要被矯直。鋼管經(jīng)矯直后由傳送帶送至金屬探傷機(jī)(或水壓實(shí)驗(yàn))進(jìn)行內(nèi)部探傷。若鋼管內(nèi)部有裂紋,氣泡等問(wèn)題,將被探測(cè)出。鋼管質(zhì)檢后還要通過(guò)嚴(yán)格的手工挑選。鋼管質(zhì)檢后,用油漆噴上編號(hào)、規(guī)格、生產(chǎn)批號(hào)等。并由吊車(chē)吊入倉(cāng)庫(kù)中。:http//www.dadipump.cn
