**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)，哈爾濱大頭硅碳棒經(jīng)銷商。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(zhǎng)度的電阻值，一般以Ω/m為單位，哈爾濱大頭硅碳棒經(jīng)銷商。一般硅碳棒測(cè)電阻測(cè)的都是單位長(zhǎng)度的電阻值。那么串聯(lián)時(shí)跟長(zhǎng)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(zhǎng)度跟粗細(xì)帶來的影響。硅碳棒相比一般的電阻元件長(zhǎng)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(zhǎng)度100的棒跟直徑40長(zhǎng)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)，哈爾濱大頭硅碳棒經(jīng)銷商。奧翔硅碳不斷從事技術(shù)革新，改進(jìn)生產(chǎn)工藝，提高技術(shù)水平。哈爾濱大頭硅碳棒經(jīng)銷商</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。 </p><p>
