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，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，廣西粗端部硅碳棒規(guī)格。　　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，其長度要略長于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，廣西粗端部硅碳棒規(guī)格，廣西粗端部硅碳棒規(guī)格，需要注意的就是要做好使用前的選型，保證它的使用效果。奧翔硅碳生產(chǎn)的設(shè)備產(chǎn)品質(zhì)量上乘。廣西粗端部硅碳棒規(guī)格</p><div

style="text-indent:25px">　等直徑硅碳棒的使用時(shí)的準(zhǔn)備事項(xiàng)，在安裝在不同的使用位置時(shí)要特別注意做好前期的準(zhǔn)備工作，這個(gè)樣有利于棒延長使用壽命，發(fā)揮棒的價(jià)值。　　1、新爐或久未使用的電爐，在使用之前必須烘爐，烘爐時(shí)盡可能用舊棒或其它熱源。　　2、注意防止等直徑硅碳棒負(fù)荷使用，如棒因故斷裂或發(fā)現(xiàn)棒發(fā)熱不均，局部呈白熾或暗紅現(xiàn)象一段一段時(shí)，這說明棒體老化不一致，一段段電阻相差太大，應(yīng)停爐檢修換棒，全部更換新棒，如更換部分新棒或單支棒時(shí)會(huì)因新棒電阻與舊棒的電阻匹配不合適，導(dǎo)致負(fù)荷不平衡，爐溫不均勻。因電阻差異大，故棒溫高低相關(guān)也打，會(huì)嚴(yán)重影響使用壽命。　　3、如果燒制器件時(shí)，在加熱過程中有水分排出，所用電阻爐（窯）要留有排氣孔，以便排除爐（窯）內(nèi)的水份或其它廢氣，以免影響等直徑硅碳棒的使用壽命。　　4、等直徑硅碳棒的存放過程中，要注意防潮，如發(fā)現(xiàn)棒端噴鋁處變質(zhì)潮解，經(jīng)表面處理后可重新噴鋁，如無噴鋁條件，可在棒噴鋁段纏裹幾層鋁箔即可。　　5、等直徑硅碳棒安裝使用前先檢查冷端部標(biāo)記的電阻（Ω）值，如字跡不清，須重新測(cè)試，測(cè)試方法是將硅碳棒通電加熱升溫至1050℃的高溫時(shí)測(cè)得的電壓，電流，以歐姆定律求的電阻。

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。奧翔硅碳愿和各界朋友真誠合作一同開拓。廣西粗端部硅碳棒規(guī)格</p><p

**近很多客戶聯(lián)系我們，把他們?cè)诠杼及舻氖褂眠^程中遇到的問題向我們請(qǐng)教，希望我們能給予幫助，小編就這些問題中的關(guān)于硅碳棒電阻值方面的知識(shí)與大家共同探討一下，希望能給廣大客戶朋友們帶來啟發(fā)與幫助，讓大家對(duì)硅碳棒有一個(gè)深層次的了解。這樣大家在以后使用過程中時(shí)也能做到心中有數(shù)，不慌不忙，發(fā)揮出硅碳棒的比較大作用。大家在使用硅碳棒的時(shí)候有時(shí)會(huì)遇到需要硅碳棒串聯(lián)的情況，那就需要挑選合適的硅碳棒進(jìn)行串聯(lián)。一般硅碳棒廠家會(huì)告訴用戶使用電阻值相近的棒進(jìn)行串聯(lián)，這個(gè)電阻值指的是硅碳棒單位長度的電阻值，一般以Ω/m為單位。一般硅碳棒測(cè)電阻測(cè)的都是單位長度的電阻值。那么串聯(lián)時(shí)跟長度與粗細(xì)有沒有關(guān)系呢？為什么是單位電阻值而不是整根的電阻值？把兩根硅碳棒視作兩個(gè)電阻元件，不應(yīng)該是整體電阻相似所以分壓一樣嗎?硅碳棒不同于一般的電阻元件，一般的電阻元件由于體積小，發(fā)熱小，所以忽視長度跟粗細(xì)帶來的影響。硅碳棒相比一般的電阻元件長度大得多，并且主要利用的是發(fā)熱而不是電阻的大小，所以串聯(lián)時(shí)就不能忽視體積的因素。比如說一根直徑20，長度100的棒跟直徑40長度200的棒，假如說兩根棒的電阻一樣，那么即使電阻一樣也不能串聯(lián)。廣西粗端部硅碳棒規(guī)格</p><p
