GB3087鍋爐管的地位。據(jù)不完全統(tǒng)計，我國現(xiàn)有無縫管生產(chǎn)企業(yè)約240多家，無縫鋼管機(jī)組約250多套，年產(chǎn)能力約450多萬噸。從口徑看，<φ76的，占35%，<φ159-650的，占25%。從品種看，一般用途管190萬噸，占54%；石油管76萬噸，占5.7%；液壓支柱、精密管15萬噸，占4.3%；不銹管、軸承管、汽車管共5萬噸，占1.4%。 </p> <p> GB3087鍋爐管的原料是圓管坯，圓管胚要經(jīng)過切割機(jī)的切割加工成長度約為1米的坯料，并經(jīng)傳送帶送到熔爐內(nèi)加熱。鋼坯被送入熔爐內(nèi)加熱，溫度大約為1200℃。燃料為氫氣或乙炔。爐內(nèi)溫度控制是關(guān)鍵性的問題.圓管坯出爐后要經(jīng)過壓力穿孔機(jī)進(jìn)行穿空。一般較常見的穿孔機(jī)是錐形輥穿孔機(jī)，這種穿孔機(jī)生產(chǎn)效率高，產(chǎn)品質(zhì)量好，穿孔擴(kuò)徑量大，可穿多種鋼種。穿孔后，圓管坯就先后被三輥斜軋、連軋或擠壓。擠壓后要脫管定徑。定徑機(jī)通過錐形鉆頭高速旋轉(zhuǎn)入鋼胚打孔，形成鋼管。鋼管內(nèi)徑由定徑機(jī)鉆頭的外徑長度來確定。鋼管經(jīng)定徑后，進(jìn)入冷卻塔中，通過噴水冷卻，鋼管經(jīng)冷卻后，就要被矯直。鋼管經(jīng)矯直后由傳送帶送至金屬探傷機(jī)（或水壓實驗）進(jìn)行內(nèi)部探傷。若鋼管內(nèi)部有裂紋，氣泡等問題，將被探測出。鋼管質(zhì)檢后還要通過嚴(yán)格的手工挑選。鋼管質(zhì)檢后，用油漆噴上編號、規(guī)格、生產(chǎn)批號等。并由吊車吊入倉庫中。

title="鍋爐管遠(yuǎn)銷海外"><br></p><div id="um8iqmy" class="khcont4"><p> 鍋爐管的用途分類 </p> <p> 用于低中壓鍋爐（工作壓力一般不大于5.88Mpa，工作溫度在450℃以下）的受熱面管子；用于高壓鍋爐（工作壓力一般在9.8Mpa以上，工作溫度在450℃～650℃之間）的受熱面管子、省煤器、過熱器、再熱器、石化工業(yè)用管等。 </p> <p> 按照組成材料分類可分為20G高壓鍋爐管、12Cr1MoVG高壓鍋爐管、鋼研102高壓鍋爐管、15CrMoG高壓鍋爐管、5310高壓鍋爐管、3087低中壓鍋爐管、40Cr高壓鍋爐管、1Cr5Mo高壓鍋爐管、42CrMo高壓鍋爐管。 </p> <p> <br /> 制造及用途 </p> <p> （1）生產(chǎn)制造方法： </p> <p> ①一般鍋爐管使用溫度在450℃以下，國產(chǎn)管主要用10號、20號碳結(jié)鋼熱軋管或冷拔管制造。 </p> <p> ②高壓鍋爐管使用時經(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?，會發(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。 </p> <p> （2）用途： </p> <p> ①一般鍋爐管主要用來制造水冷壁管、沸水管、過熱蒸汽管、機(jī)車鍋爐用的過熱蒸汽管，大、小煙管及拱磚管等。 </p> <p> ②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> 高壓鍋爐管的生產(chǎn)工藝隨鋼種的不同各有差異。以珠光體型鉻鉬釩鋼為例，鍋爐管的生產(chǎn)工藝特點是：（1）管坯應(yīng)剝皮，剝皮量通常為5mm；（2）由于鋼質(zhì)較硬，管坯多用氧氣切割或鋸切；（3）由于鉻鉬釩鋼的導(dǎo)熱性比碳鋼低，加熱速度宜稍慢，加熱溫度為1120～1180℃，穿孔溫度為1100～1160℃；（4）這類鋼在1000～1100℃區(qū)間有良好的塑性和低的變形抗力，因而穿孔性能較好，變形參數(shù)可照中碳鋼或合金鋼（例如30CrMnSiA）選??；（5）軋后鋼管要正火和回火，正火溫度為950～980℃，回火溫度為730～750℃，保溫時間為2～3h；（6）鋼管尺寸公差較嚴(yán)，以保證對口焊接；管子長度盡可能長，以利于減少焊口數(shù)量。
