高壓鍋爐管是鍋爐管的一種，屬于無縫鋼管類別。制造方法與無縫管高壓鍋爐管相同，但對制造鋼管所用的鋼種有嚴(yán)格的要求。高壓鍋爐管使用時(shí)經(jīng)常處于高溫和高壓條件。高壓鍋爐管主要用來制造高壓和超高壓鍋爐的過熱器管、再熱器管、導(dǎo)氣管、主蒸汽管等。 </p> <p> <br /> 高壓鍋爐管的熱處理：1.正火：正火溫度880℃-940℃（20G, 20MNG, 25MNG)；正火溫度890℃-950℃（15MOG,20MOG) </p> <p> 2.正火加回火：正火溫度：900℃-960℃；回火溫度680℃-730℃（15CRMOG,12CR1MOVG) </p> <p> 熱處理(Heat Treatment) - 是利用加熱和冷卻以改變高壓鍋爐管物理性質(zhì)的方法。熱處理能改善高壓鍋爐管的顯微結(jié)構(gòu), 使達(dá)到所需的物理要求。韌性, 硬度和耐磨性是通過熱處理而獲得的特性中的幾種。要獲得這些特性, 需使用熱處理中的淬硬<又稱淬火>, 回火, 退火<又稱朡化>和表面淬硬等操作。<br /> 淬硬(Hardening, 又稱淬火) - 是將高壓鍋爐管均勻地加熱至適當(dāng)溫度, 然後迅速浸入水或油中急冷, 或在空氣中或冷凍區(qū)中冷卻, 使高壓鍋爐管獲得所需要的硬度。<br /> 回火 - 高壓鍋爐管淬硬後會變脆, 同時(shí)由淬火急冷而引致的應(yīng)力, 可使高壓鍋爐管受到輕擊而斷裂。要脆性, 可用回火處理法。回火就是將高壓鍋爐管重新加熱至適當(dāng)?shù)臏囟然蝾伾? 然後予以急冷。回火雖然高壓鍋爐管的硬度略為減少, 但可增加高壓鍋爐管的韌性而降低其脆性。<br /> 退火 - 退火是高壓鍋爐管的內(nèi)在應(yīng)力和勒化鋼件的方法。退火法是將鋼件加熱至高於臨界溫度, 然後放入乾灰, 石灰, 石棉或封閉在爐內(nèi), 令它慢慢冷卻。 </p></div></div></div><div id="9hprh9l" class="box12-3"><img
