一般用(yong)(yong)無縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)是用(yong)(yong)10#、20#、30#、35#、45#等(deng)(deng)優質(zhi)碳(tan)結鋼(gang)或16Mn、5MnV等(deng)(deng)低合(he)金結構鋼(gang)或40Cr、30CrMnSi、45Mn2、40MnB等(deng)(deng)合(he)結鋼(gang)熱軋(ya)或冷軋(ya)制(zhi)成的(de)(de)。10#、20#等(deng)(deng)低碳(tan)鋼(gang)制(zhi)造的(de)(de)無縫(feng)(feng)(feng)管(guan)(guan)主要用(yong)(yong)于流(liu)體(ti)輸送管(guan)(guan)道。45#、40Cr等(deng)(deng)中碳(tan)鋼(gang)制(zhi)成的(de)(de)無縫(feng)(feng)(feng)管(guan)(guan)通常用(yong)(yong)來制(zhi)造機(ji)(ji)械零(ling)件，如汽車、拖(tuo)拉(la)機(ji)(ji)的(de)(de)受力零(ling)件。一般用(yong)(yong)無縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)要保證(zheng)強度和進(jin)行(xing)壓扁試驗。熱軋(ya)鋼(gang)管(guan)(guan)以(yi)熱軋(ya)狀態(tai)或熱處理(li)狀態(tai)交貨；冷軋(ya)以(yi)熱處理(li)狀態(tai)交貨。
熱(re)軋(ya)(ya)，顧名思義，軋(ya)(ya)件的溫(wen)度(du)(du)(du)(du)高，因此變(bian)形抗(kang)力小(xiao)，可以(yi)實(shi)現大的變(bian)形量。以(yi)鋼(gang)板(ban)的軋(ya)(ya)制為(wei)例(li)，一般連鑄坯厚(hou)度(du)(du)(du)(du)在230mm左右(you)，而經過粗軋(ya)(ya)和(he)精軋(ya)(ya)，最終(zhong)厚(hou)度(du)(du)(du)(du)為(wei)1~20mm。同時，由(you)于(yu)鋼(gang)板(ban)的寬厚(hou)比(bi)小(xiao)，尺寸精度(du)(du)(du)(du)要求(qiu)相對(dui)低，不容易(yi)出現板(ban)形問題，以(yi)控(kong)(kong)(kong)制凸(tu)度(du)(du)(du)(du)為(wei)主。對(dui)于(yu)組織有要求(qiu)的，一般通(tong)過控(kong)(kong)(kong)軋(ya)(ya)控(kong)(kong)(kong)冷來實(shi)現，即控(kong)(kong)(kong)制精軋(ya)(ya)的開軋(ya)(ya)溫(wen)度(du)(du)(du)(du)、終(zhong)軋(ya)(ya)溫(wen)度(du)(du)(du)(du)和(he)卷曲溫(wen)度(du)(du)(du)(du)來控(kong)(kong)(kong)制帶(dai)鋼(gang)的微觀組織和(he)機(ji)械性能。
