style="text-indent:25px">雙螺紋硅碳管是用高精度碳化硅（SIC）為主要原料、經(jīng)高溫（2200℃）再結(jié)晶制成的非金屬電熱元件。使用比較高溫度1600℃，正常使用溫度1450攝氏度，連續(xù)使用壽命可達(dá)3000小時(shí)以上。　　發(fā)熱原理：在外加電能量作用下，電子和空穴的輻射復(fù)合發(fā)生電致發(fā)光，在PN結(jié)附近輻射出來(lái)的光還需經(jīng)過(guò)碳管本身的半導(dǎo)體介質(zhì)和封裝介質(zhì)才能抵達(dá)外界（空氣）。綜合電流注入效率、輻射發(fā)光量子效率、碳管外部光取出效率等，**終大概只有60-70％的能量主要以非輻射復(fù)合發(fā)生的點(diǎn)陣振動(dòng)的形式轉(zhuǎn)化熱能。</p><p> 滿(mǎn)足了各使用廠(chǎng)家的需求，具有冷熱端焊接點(diǎn)牢固不易斷；熱端發(fā)熱均勻，1300℃下溫差在40℃之內(nèi)；長(zhǎng)期高溫狀態(tài)下使用壽命長(zhǎng)等特點(diǎn)。在某些應(yīng)用場(chǎng)合產(chǎn)品性能接近或達(dá)到國(guó)外品牌硅碳棒技術(shù)指標(biāo)，可以替代進(jìn)口。④使用溫度硅碳棒溫度越高壽命越短。特別是在爐膛溫度超過(guò)1600℃以后，氧化速度加快，硅碳棒的使用壽命變短，所以請(qǐng)盡量不要讓硅碳棒表面溫度過(guò)高，即有必要縮小爐膛溫度與硅碳棒溫度之差。⑤表面負(fù)荷表面負(fù)荷密度指棒的發(fā)熱部單位表面積所允許承載的額定功率。表面負(fù)荷密度=額定功率（W）/發(fā)熱部表面積（cm2）實(shí)踐證明：負(fù)荷密度大則發(fā)熱體表面溫度與爐膛溫度之差也大。負(fù)荷密度大則棒體表面溫度高，電阻增長(zhǎng)快，SIC棒的壽命短。因此，硅碳棒表面溫度負(fù)荷密度、爐內(nèi)氣氛、溫度與SIC棒老化速度成正比，與SIC棒的壽命成反比。奧翔硅碳是多層次的模式與管理模式。</p><div

硅碳棒廠(chǎng)家介紹，硅碳棒坯是次燒結(jié)，然后嵌入二氧化硅和碳的混合粉末中。采用電加熱法在2000年高溫下對(duì)碳化硅進(jìn)行再結(jié)晶，得到硅碳棒電熱元件，稱(chēng)為二次燒結(jié)，也稱(chēng)為硅化。二氧化硅和碳的混合粉末主要在高溫下在硅碳棒坯周?chē)纬蛇€原氣氛，硅碳棒坯的氧化，促進(jìn)硅碳棒中碳化硅晶體的生長(zhǎng)。在第二次燒結(jié)過(guò)程中，SiC晶體的晶粒尺寸越大，SiC棒的電阻率和表面系數(shù)越小，從而使SiC棒不被氧化，從而提高了SiC棒的壽命。然而，使用二氧化硅和碳會(huì)導(dǎo)致硅碳棒坯中碳化硅顆粒不均勻生長(zhǎng)，造成硅碳棒表面粗糙，影響硅碳棒的質(zhì)量。1、幾何尺寸的選擇電爐的爐膛是由被加熱物的尺寸推算而決定，因而硅碳管的尺寸也相應(yīng)確定下來(lái)，現(xiàn)舉例說(shuō)明如下：如被加熱物是?70×500mm的石英管（這里的500mm是指石英管的受熱區(qū)，實(shí)際上石英管還要長(zhǎng)）則硅碳管的規(guī)格可選用?90/80×500/100，二爐膛的高鋁管則可選用其內(nèi)徑為100mm，其長(zhǎng)度要略長(zhǎng)于500mm。2、硅碳棒保護(hù)管使用的功率硅碳管使用的功率決定于爐子的保溫條件，幾何尺寸及到達(dá)的溫度。對(duì)于較好的保溫條件，恒溫后，硅碳管發(fā)熱區(qū)內(nèi)表面的溫度與被加熱物的溫度相差≦50℃。我們可以利用下式先計(jì)算硅碳管發(fā)熱部單位表面積的負(fù)荷。奧翔硅碳擁有業(yè)內(nèi)**人士和高技術(shù)人才。廣東螺旋硅碳管廠(chǎng)</p><p
