style="text-indent:25px">等直徑硅碳棒在使用過程中，有些時(shí)候燒過一爐之后會(huì)出現(xiàn)白色水珠樣的東西，為什么會(huì)出現(xiàn)這樣的情況呢？就給大家解答疑惑。　　它的混料比例是用高純度綠色六方碳化硅為主要原料，按一定料比加工制坯，經(jīng)2200℃高溫硅化再結(jié)晶燒結(jié)而制成的棒狀、管狀非金屬高溫電熱元件。從原材料來說里面不存在白色物質(zhì)，在混料中，屬于白色物質(zhì)就屬于氮化硼，幾十公斤添加幾克的配方，在每個(gè)棒都出現(xiàn)白色來說肯定不是這方面的原因。　　等直徑硅碳棒出現(xiàn)白色物質(zhì)與天氣有關(guān)，存放保存有關(guān)，主要還是水汽，在新爐子使用的時(shí)候首先一定要用舊棒烘爐，帶到爐子干了之后再用新棒燒結(jié)，爐子長(zhǎng)時(shí)間不用使用的時(shí)候都要先烘爐，可以先把爐門打開一段時(shí)間，升一會(huì)之后排出水汽在關(guān)閉爐門，這樣處理之后就不會(huì)出現(xiàn)白色的物質(zhì)了。　　其實(shí)這個(gè)現(xiàn)象也說明大家對(duì)與等直徑硅碳棒的使用還不是特別的正確，如果能夠比較規(guī)范的使用它就可以避免很多不必要的意外狀況。陜西門型硅碳棒功率奧翔硅碳不懈追求產(chǎn)品質(zhì)量，精益求精不斷升級(jí)。</p><div

style="text-indent:25px">螺旋硅碳棒不**是在加熱爐里使用，而且也可以是測(cè)硫儀**硅碳管，主要用于灰分熔點(diǎn)測(cè)定儀，煤炭活性測(cè)定儀，雙管定硫儀，膠質(zhì)層（Y值）等，我們都知道的是以高純度SiC為主要原料，經(jīng)高溫再結(jié)晶制成的一種新型管狀電熱元件。　　螺旋硅碳棒做為管狀電熱元件來講，是一種很理想的產(chǎn)品，它不但比鎳鉻絲電熱元件使用的溫度高、壽命長(zhǎng)，而且發(fā)熱均勻，升溫快，可以節(jié)約電能，并可取得相當(dāng)理想的溫區(qū)，如果配制適當(dāng)容量的調(diào)壓變壓器，它可以達(dá)到你需要的理想溫度，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可以根據(jù)它來確定下來。　　比如被加熱物是φ70×500mm的石英管，則螺旋硅碳棒的規(guī)格可選用φ90/80×500/100，而爐膛的高鋁管則可選用其內(nèi)徑位100mm，其長(zhǎng)度要略長(zhǎng)于500mm。　　所以螺旋硅碳棒用作電熱元件是一個(gè)越來越被認(rèn)可的材料，需要注意的就是要做好使用前的選型，保證它的使用效果。</p><p

SIC棒的壽命短。因此，螺旋硅碳棒表面溫度負(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。使用等直徑硅碳棒的用戶都知道，等直徑硅碳棒元件工作發(fā)紅的部位在熱端，在1000多度以上時(shí)熱端部位是不適宜用眼睛直視的?，F(xiàn)實(shí)使用中也有用戶反映冷端發(fā)紅的現(xiàn)象，這個(gè)現(xiàn)象是不正常的，造成冷端發(fā)紅主要有以下原因：　　1、等直徑硅碳棒元件的連接帶、卡具沒有卡緊，卡具連接應(yīng)進(jìn)行二次緊固，一次安裝不要擰的太緊，升到高溫時(shí)再次擰緊。　　2、冷端直徑做的細(xì)了，與發(fā)熱部不匹配，3mm的發(fā)熱部應(yīng)配6mm的冷端，4mm的配9mm的冷端，6mm的配12mm的冷端，7mm的配14mm的冷端，9mm的配18mm的冷端，12mm的配24mm的冷端。　　當(dāng)我們?cè)趯?duì)等直徑硅碳棒進(jìn)行工作使用的時(shí)候，了解了這些方向之后我們?cè)谔幚淼臅r(shí)候才能更加的方便快捷。奧翔硅碳以發(fā)展求壯大，就一定會(huì)贏得更好的明天。</p><div

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高，即有必要縮小爐膛溫度與硅碳棒溫度之差。 ②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。陜西門型硅碳棒功率</p><p
