加熱用的輻射管有直單管、直套管（包括單孔燒嘴和多孔燒嘴）和U形管等。直單管單孔燒嘴輻射管管面的溫度較低，使用壽命較長，結(jié)構(gòu)簡單，易于維修，價格也比較便宜。但是由于進(jìn)入的空氣溫度低，產(chǎn)生的廢氣溫度較高，因而熱效率較低，只有30%左右。另外，由于是單孔燒嘴，其噪聲較大，在管子的長度方向上，溫度分布也不均勻。作為改進(jìn)型，使用多孔燒嘴，可以降低噪聲，改善長度方向上的熱量分布狀態(tài)。使用直套管式輻射管，可以利用燃燒排出的廢氣來預(yù)熱助燃空氣，使其溫度達(dá)到450攝氏度。這樣熱效率可提髙1倍以上。在長度方向上的溫度分布也比單直管式均勻，不過，由于直套管式輻射管是雙層結(jié)構(gòu)，外層管的溫度自然要低于內(nèi)層管，這樣，為了保護(hù)內(nèi)管不會因溫度過髙而燒壞，只好限制外管的溫度，從而使加熱能力有所降低，由于內(nèi)管的溫度較髙，所以使用壽命也低^U形輻射管具有單管和套管兩種類型輻射管的優(yōu)點(diǎn)，它一端為燒嘴，另一端為空氣預(yù)熱器，爐內(nèi)加熱部分則為單層。輻射管長期在950-1100攝氏度的溫度范圍內(nèi)工作，其內(nèi)層接觸的是燃燒氣體，在外側(cè)接觸的則是爐內(nèi)保護(hù)氣氛。在燃燒氣體中，主要成分是N2、02、CO和C02。在髙溫條件下，CO、N2和02都將對輻射管壁起破壞作用。</p><div

高溫電熱輻射管特點(diǎn)：1、選用質(zhì)量原材料生產(chǎn)的無縫冷拔耐熱鋼管（比較高溫度為1200度）制造2、內(nèi)芯采用電阻絲U型軸向排列端部焊接方式3、電阻絲與陶瓷架基本上無屏蔽，電阻絲與爐膛溫差小4、比較高工作溫度1000度或1200度5、本公司生產(chǎn)的輻射管比較大的優(yōu)點(diǎn)是選用無縫冷拔、薄壁耐熱鋼管（1Cr25Ni20Si2或0Cr25Ni20Si2），其產(chǎn)品的熱輻射比同類產(chǎn)品高10%6、使用8000h以上輻射管使用的電熱合金材料應(yīng)具有較高的電阻率，電熱轉(zhuǎn)化率高。由于輻射管放置在套管內(nèi)，傳熱過程與一般敞露型電熱元件不同，其熱屏蔽大，升溫過程中必須對元件溫度進(jìn)行控制，防止元件超溫。輻射管封閉加熱時，電熱元件表面溫度比爐膛溫度高約100℃-150℃。所以在選材時要分析爐溫、爐內(nèi)氣溫氛圍，選擇正確的加熱材料。本公司生產(chǎn)的輻射管常使用Cr20Ni80（鎳鉻系）Cr25A15、Cr21A16Nb、Cr27A17Mo2（鐵鉻鋁系）等材料，各材料化學(xué)成份/%如下表：Cr20Ni80使用在500℃-800℃之間，因其穩(wěn)定的、單一的、均勻的固熔體，所以具有良好的常溫和高溫力學(xué)性質(zhì)，均勻的電氣物理性質(zhì)以及良好的加工工藝性質(zhì)。使用溫度低，使用壽命長，不易損壞等方面區(qū)別于鐵鉻鋁系電熱合金材料。</p></p><br
