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。如被加熱物及管內(nèi)環(huán)境溫度要求達(dá)到1250℃，硅碳管內(nèi)表面溫度計(jì)劃用到1300℃，則這時(shí)硅碳管單位面積的負(fù)荷為。影響硅碳棒保護(hù)管使用壽命的主要因素：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。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。爐膛溫度與表面負(fù)荷密度的關(guān)系：使用范圍曲線(xiàn)為表面負(fù)荷密度臨界線(xiàn)，實(shí)際情況下請(qǐng)保持臨界線(xiàn)的1/2—1/3的表面負(fù)荷。在燒成中硅碳棒保護(hù)管與很多燒成物揮發(fā)出來(lái)的化學(xué)物質(zhì)之間的會(huì)發(fā)生反應(yīng)。
