厚壁無縫鋼管的常識

無(wu)縫(feng)鋼(gang)管(guan)(guan)是(shi)如(ru)今運用(yong)非常(chang)廣(guang)泛的(de)制(zhi)造(zao)結構件和機械零件,如(ru)石油鉆桿、汽車(che)傳動軸、自(zi)行(xing)車(che)架(jia)以及修建施工頂(ding)用(yong)的(de)鋼(gang)腳(jiao)手架(jia)等都(dou)會用(yong)到(dao)無(wu)縫(feng)鋼(gang)管(guan)(guan),而無(wu)縫(feng)鋼(gang)管(guan)(guan)有(you)很(hen)多類(lei)型(xing),厚壁無(wu)縫(feng)鋼(gang)管(guan)(guan)便是(shi)一(yi)種(zhong)熱銷(xiao)的(de)類(lei)型(xing),下面無(wu)縫(feng)鋼(gang)管(guan)(guan)廠家就給我們介(jie)紹(shao)了(le)厚壁無(wu)縫(feng)鋼(gang)管(guan)(guan)的(de)常(chang)識,希望對我們有(you)所幫助.

一般厚(hou)壁(bi)(bi)無(wu)縫(feng)鋼管(guan)(guan)(guan)指的是(shi)壁(bi)(bi)厚(hou)在20毫(hao)米以上,其與薄壁(bi)(bi)無(wu)縫(feng)鋼管(guan)(guan)(guan)的差異首要也(ye)便是(shi)在鋼管(guan)(guan)(guan)壁(bi)(bi)的厚(hou)度上,一般以為,壁(bi)(bi)厚(hou)/管(guan)(guan)(guan)徑等(deng)于(yu)0.02是(shi)厚(hou)壁(bi)(bi)鋼管(guan)(guan)(guan)和薄壁(bi)(bi)鋼管(guan)(guan)(guan)的分水嶺(ling),壁(bi)(bi)厚(hou)/管(guan)(guan)(guan)徑小于(yu)0.02的是(shi)薄壁(bi)(bi)鋼管(guan)(guan)(guan),大于(yu)的是(shi)厚(hou)壁(bi)(bi)鋼管(guan)(guan)(guan).

厚壁無(wu)縫鋼管的制(zhi)造進程解(jie)析:

厚壁無縫(feng)鋼(gang)(gang)管(guan)的(de)(de)原(yuan)料(liao)是(shi)鋼(gang)(gang)管(guan)坯(pi)(pi)料(liao),使用切割機(ji)(ji)將管(guan)坯(pi)(pi)加工成(cheng)長(chang)度大約(yue)為(wei)1米(mi)的(de)(de)坯(pi)(pi)料(liao),再通(tong)過(guo)熔爐(lu)(lu)內(nei)加熱,溫(wen)度大約(yue)為(wei)1200攝氏(shi)度(需求注意(yi)的(de)(de)是(shi)爐(lu)(lu)內(nei)溫(wen)度控制的(de)(de)是(shi)比(bi)較(jiao)關(guan)鍵性(xing)的(de)(de)一(yi)個(ge)問題),圓管(guan)坯(pi)(pi)出爐(lu)(lu)后要通(tong)過(guo)壓(ya)力穿(chuan)(chuan)孔(kong)(kong)機(ji)(ji)進行穿(chuan)(chuan)孔(kong)(kong),一(yi)般比(bi)較(jiao)常見的(de)(de)是(shi)穿(chuan)(chuan)孔(kong)(kong)機(ji)(ji)是(shi)錐(zhui)形輥(gun)穿(chuan)(chuan)孔(kong)(kong)機(ji)(ji),這(zhe)種(zhong)(zhong)穿(chuan)(chuan)孔(kong)(kong)機(ji)(ji)出產效率高(gao),產品質量(liang)也好,穿(chuan)(chuan)孔(kong)(kong)擴(kuo)徑(jing)量(liang)大,可以穿(chuan)(chuan)多種(zhong)(zhong)鋼(gang)(gang)種(zhong)(zhong),穿(chuan)(chuan)孔(kong)(kong)后,圓管(guan)坯(pi)(pi)就先后被三輥(gun)斜軋、連軋或(huo)者(zhe)擠(ji)(ji)壓(ya),擠(ji)(ji)壓(ya)之后要脫管(guan)定(ding)徑(jing),定(ding)徑(jing)機(ji)(ji)通(tong)過(guo)錐(zhui)形鉆頭(tou)高(gao)速旋轉入鋼(gang)(gang)坯(pi)(pi)打孔(kong)(kong)從(cong)而形成(cheng)了鋼(gang)(gang)管(guan).

一般(ban)厚壁(bi)無縫(feng)鋼管分為兩(liang)種(zhong),一種(zhong)是熱軋(ya)無縫(feng)鋼管,一種(zhong)便是熱擴無縫(feng)鋼管,大多厚壁(bi)鋼管一般(ban)使用熱軋(ya)技術.
