class="khcont">根據(jù)生產(chǎn)方法，無縫管分熱軋管、冷軋管、冷拔管、擠壓管、頂管等。按照斷面形狀，無縫鋼管分圓形和異形兩種，異形管有方形、橢圓形、三角形、六角形、瓜子形、星形、帶翅管多種復(fù)雜形狀。直徑達650mm，直徑為 0.3mm。根據(jù)用途不同，有厚壁管和薄壁管。無縫鋼管主要用做石油地質(zhì)鉆探管、石油化工用的裂化管、鍋爐管、軸承管以及汽車、拖拉機、用高精度結(jié)構(gòu)鋼管。精密鋼管是一種通過冷拔或熱軋?zhí)幚砗蟮囊环N高精密的鋼管材料。由于精密鋼管內(nèi)外壁無氧化層、承受高壓無泄漏、高精度、高光潔度、冷彎不變形、擴口、壓扁無裂縫等優(yōu)點，所以主要用來生產(chǎn)氣動或液壓元件的產(chǎn)品，如氣缸或油缸，可以是無縫管，也有焊接管。方管，是方形管材的一種稱呼，也就是邊長相等的的鋼管。是帶鋼經(jīng)過工藝處理卷制而成。焊接鋼管也稱焊管，是用鋼板或帶鋼經(jīng)過卷曲成型后焊接制成的鋼管，一般定尺6米。焊接鋼管生產(chǎn)工藝簡單，生產(chǎn)效率高，品種規(guī)格多，設(shè)備投資少，但一般強度低于無縫鋼管。鍍鋅管，又稱鍍鋅鋼管，分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強，使用壽命長等優(yōu)點。電鍍鋅成本低，表面不是很光滑，其本身的耐腐蝕性比熱鍍鋅管差很多。</div><p><img

管坯在加熱環(huán)節(jié)如果升溫速度過快、保溫時間不夠便會導(dǎo)致穿軋后的厚壁管在壁厚方向上呈現(xiàn)晶粒度及組織的不一致，近而在冷拔過程中出現(xiàn)顯微變形差異，聚集到一定程度便會釋放形成橫裂。我們只要在冷拔前增加一個道次的半品退火即可壁厚方向上組織、性能的異向，避免橫裂的發(fā)生。無縫鋼管主要用做石油地質(zhì)鉆探管、石油化工用的裂化管、鍋爐管、軸承管以及汽車、拖拉機、航空用高精度結(jié)構(gòu)管等。國內(nèi)常用材質(zhì)為：10#20mn42crmo36CrMo40Cr20Cr15CrMo12Cr1MovQ235A，Q235B、0Cr13、1Cr17、00Cr19Ni11、1Cr18Ni9、0Cr18Ni11Nb、16Mn、20#、45#，Q345、L245、L290、X42、X46、X70、X80。

精密管中合金元素對低溫回火脆性產(chǎn)生較大的影響。鉻和錳促進雜質(zhì)元素磷等在奧氏體晶界偏聚，從而<br /> 促進低溫回火脆性，鎢和釩基本上沒有影響，鉬降低低溫回火精密管的韌性一脆性轉(zhuǎn)化溫度，但尚不足<br /> 以抑制低溫回火脆性。硅能推遲回火時滲碳體析出，提高其生成溫度，故可提高精密管低溫回火脆性發(fā)<br /> 生的溫度。<br /> 膨脹系數(shù)編輯<br /> 檢查的方法可以用肥皂水抹在退火爐各個接頭縫隙處，看是否跑氣；其中容易跑氣的地方是退火爐進<br /> 管子的地方和出管子的地方，這個地方的密封圈特別容易磨損，要經(jīng)常檢查經(jīng)常換。提出了冷彎成型前<br /> 對無錫精密鋼管進行預(yù)處理的工藝方案;研究分析了正火溫度、保溫時間和冷卻方式對原料管組織和力學(xué)<br /> 性能的影響規(guī)律;確定了無錫精密鋼管的常規(guī)正火工藝:加熱溫度(890±10)℃,保溫6min后散置空冷。常<br /> 規(guī)正火工藝可完全無錫精密鋼管的魏氏組織,使其屈服強度和抗拉強度的匹配更加合理,屈強比σS/b<br /> σ≤0.78,延伸率5δ≥30%,冷成型性能大幅度提高并避免出現(xiàn)冷彎開裂現(xiàn)象。膨脹系數(shù)可以用體積或者<br /> 是長度表示，通常是用長度表示。密度物質(zhì)的密度是該物質(zhì)單位體積的質(zhì)量，單位是kg/m3或1b/in3。殘<br /> 余拉應(yīng)力主要來自設(shè)備在焊接過程中產(chǎn)生的殘余拉應(yīng)力。當(dāng)前，工程上廣泛采用焊接冷卻后進行退火處<br /> 理殘余應(yīng)力，而焊后冷卻是殘余應(yīng)力產(chǎn)生的重要過程，這種做法既浪費了能源又容易產(chǎn)生較大的焊<br /> 接殘余應(yīng)力。焊接后熱處理是一種新的殘余應(yīng)力技術(shù)。焊前將無錫精密鋼管預(yù)熱至后熱處理溫度并<br /> 在焊接過程中對焊件持續(xù)加熱保持這一溫度，焊接完成后使用保溫棉對其進行保溫使其緩慢冷卻。淬火<br /> 能增加鋼管的強度和硬度，但要減少其塑性。淬火中常用的淬火劑有水、油、堿水和鹽類溶液等。無錫<br /> 精密鋼管的回火將已經(jīng)淬火的無錫精密鋼管重新加熱到一定溫度，再用一定方法冷卻稱為回火。其目的<br /> 是淬火產(chǎn)生的內(nèi)應(yīng)力，降低硬度和脆性，以取得預(yù)期的力學(xué)性能。回火分高溫回火、中溫回火和低<br /> 溫回火三類。回火多與淬火、正火配合使用。調(diào)質(zhì)處理淬火后高溫回火的熱處理方法稱為調(diào)質(zhì)處理。 </p> <p> </p></div><div id="osmycuu" class=imgtipsbox>點擊查看金寶倉金屬制品(宜春市上高縣分公司)的<a href="/shanggaolchhwy/picture.html"><span
