</p> <p> T22質(zhì)量控制<br /> 1管坯控制 </p> <p> 管坯對(duì)無(wú)縫鋼管生產(chǎn)具有較大影響，主要表現(xiàn)為鋼的化學(xué)成分的穩(wěn)定及鋼的純凈度方面。一般高壓管坯通常采用"電爐+LF+VD"生產(chǎn)流程，電弧爐主要用于冶煉出合格的粗鋼水，LF爐除對(duì)鋼水進(jìn)行脫氧、脫硫和溫度控制外，重要的任務(wù)是調(diào)整鋼水的化學(xué)成分，VD爐主要是凈化鋼液，保證鋼水的純凈度。根據(jù)高壓鍋爐管的應(yīng)用特點(diǎn)，要求鍋爐鋼在冶煉控制技術(shù)方面，除化學(xué)成分要命中目標(biāo)以外，還要求鍋爐鋼純凈度要高，S、P有害元素控制要低，特別是S元素要嚴(yán)格控，主要因?yàn)镾元素是引起原晶界弱化的主要雜質(zhì)元素，是導(dǎo)致鋼蠕變脆化的主要因素。長(zhǎng)期以來(lái)鍋爐管都是采用鍛軋管坯制造的，鍛軋管坯不僅可以在鋼錠上切除縮孔、夾渣等澆鋼缺陷，同時(shí)也可以通過(guò)大的軋制變形殘留的缺陷。 </p> <p> 近年來(lái)隨著冶金工藝裝備水平的大幅度，管坯連鑄連軋生產(chǎn)工藝以其、低耗、優(yōu)質(zhì)、低成本優(yōu)勢(shì)得到迅速推廣，管坯廠為了保證表面質(zhì)量一般配有鋼棒漏磁探傷、超聲波相控陣探傷或紅外探傷等檢測(cè)手段，發(fā)現(xiàn)缺陷進(jìn)行表面扒皮等相關(guān)配套手段。 </p> <p> 2熱處理工序控制要點(diǎn) </p> <p> 在鍋爐用無(wú)縫鋼管生產(chǎn)工序中，熱處理是關(guān)鍵工序，熱處理對(duì)無(wú)縫鋼管的內(nèi)在質(zhì)量及表面質(zhì)量產(chǎn)生重要影響，對(duì)生產(chǎn)合金無(wú)縫鋼管尤為重要，對(duì)電站鍋爐用高壓鍋爐管的持久性能影響較大，穩(wěn)定的金相組織和良好的內(nèi)外表面質(zhì)量代表鋼管企業(yè)的制造水平。鋼管的化學(xué)成分確定之后，終賦予鋼管優(yōu)良力學(xué)性能和內(nèi)在組織的是熱處理工藝，ASME標(biāo)準(zhǔn)給出的工藝參數(shù)范圍較寬，生產(chǎn)企業(yè)需現(xiàn)場(chǎng)試驗(yàn)，找出合適的熱處理工藝。T22的通常熱處理工藝:920℃-940℃正火，保溫大于20分鐘;720℃-740℃回火，保溫2h。 </p> <p> 3無(wú)損檢測(cè)的控制 </p> <p> 一般國(guó)內(nèi)鍋爐企業(yè)按照GB5310或企業(yè)采購(gòu)規(guī)程(訂貨技術(shù)條件)進(jìn)行采購(gòu)高壓鍋爐管，無(wú)損檢測(cè)一般采用渦流及超聲波自動(dòng)探傷，要求鋼管逐根進(jìn)行渦流探傷，渦流探傷方法及驗(yàn)收標(biāo)準(zhǔn)按GB7735較高級(jí)控制;鋼管逐根進(jìn)行超聲波探傷，探傷方法按GB5777級(jí)，所有規(guī)格鋼管的驗(yàn)收標(biāo)準(zhǔn)應(yīng)符合L2級(jí)的規(guī)定;出口管或按照ASME SA-213標(biāo)準(zhǔn)交貨的鋼管的無(wú)損檢測(cè)按照SA-450進(jìn)行控制。超聲波測(cè)厚、斜向傷檢測(cè)功能開(kāi)始在國(guó)產(chǎn)自動(dòng)探傷設(shè)備配置，將較好地國(guó)產(chǎn)設(shè)備的性能，同時(shí)有效地檢測(cè)鋼管內(nèi)分層缺陷。 </p> <p> </p> <p>

20G高壓鍋爐管是，但對(duì)制造鋼管所用的鋼種有嚴(yán)格的要求。20G高壓鍋爐管使用時(shí)經(jīng)常處于高溫和高壓條件，管子在高溫?zé)煔夂退魵獾淖饔孟?，?huì)發(fā)生氧化和腐蝕。要求鋼管具有高的持久強(qiáng)度，高的抗氧化腐蝕性能，并有良好的組織穩(wěn)定性。高壓鍋爐管主要用來(lái)制造高壓和超高壓鍋爐的過(guò)熱器管、再熱器管、導(dǎo)氣管、主蒸汽管等。 </p> <p> 20G高壓鍋爐管采用的鍋爐受壓元件用鋼,一般在39公斤以下的鍋爐應(yīng)用，為了在較高壓力下使用，往往都把受熱面管設(shè)計(jì)的很厚。為了減少熱阻和節(jié)省鋼材，保證較高或高壓鍋爐用鋼的性，同時(shí)也為了降低用鋼量，普遍采用的是16MnG。同時(shí)也有添加稀土、鎂等金屬和非金屬材料的特殊鋼材。這樣會(huì)提高鍋爐用鋼的性能，減少鋼材的耗量，同時(shí)也降低了熱阻。
