style="text-indent:25px">硅碳棒在連續(xù)式窯爐與間歇式窯爐中，前者的壽命較長。硅碳棒在使用中表面氧化生成二氧化硅薄膜，長時間使用使二氧化硅皮膜增加，硅碳棒阻值也隨之增加。二氧化硅薄膜在結(jié)晶臨界點(diǎn)（270℃）附近發(fā)生異常膨脹、收縮。因在間歇式窯爐中間斷使用總在此溫度上下浮動，所以反復(fù)破二氧化硅薄膜，加速氧化，新疆三相硅碳棒。因此停電爐溫降至室溫時經(jīng)常急劇增加電阻。如果硅碳棒阻值不同，串聯(lián)時電阻高的硅碳棒負(fù)荷較集中，易導(dǎo)致某一根硅碳棒的電阻快速增加，壽命變短。硅碳棒一般是串、并聯(lián)接線結(jié)合使用。建議采用2根串聯(lián)為一組后多組并聯(lián)，新疆三相硅碳棒。特別當(dāng)爐內(nèi)溫度超過1350℃時必須并聯(lián)。三相接線時建議使用開放三角形接線。公司狠抓產(chǎn)品質(zhì)量的提高，新疆三相硅碳棒，逐年立項對制造、檢測、試驗裝置進(jìn)行技術(shù)改造。新疆三相硅碳棒</p><div

新爐或久未使用的爐窯，在使用之前必須烘爐，烘爐時應(yīng)用舊硅碳棒或其它熱源，切勿用新硅碳棒烘滬新爐開始送電時，為了防止意外，開始的一段時間好采用電阻爐額定功率的1-2送電，一切正常后，再逐漸升高電壓，按電爐升溫規(guī)范升溫。當(dāng)發(fā)現(xiàn)硅碳棒發(fā)熱不均，局部白熾或暗紅，或發(fā)現(xiàn)斷硅碳棒時，這說明硅碳棒老化不均，各硅碳棒電阻值相差太大。這時應(yīng)停滬換硅碳棒，好全部更換以利電阻匹配，保證硅碳棒的正常壽命.舊硅碳棒可作烘爐時使用.水蒸汽對硅碳棒壽命有很大影響，對被加熱物含水份過高的應(yīng)予先干燥.在加熱過程中有水分排出的，應(yīng)在低沮的水分排出段設(shè)置排氣孔。的爐內(nèi)的金屬氧化物、熔渣以及其他雜物，應(yīng)及時處理，不得積存爐內(nèi)，防止和硅碳棒接觸，降低元件壽命。硅碳棒存放應(yīng)注意防潮，若噴鋁層潮解，應(yīng)重新噴鋁，或安裝時在噴鋁段纏裹幾層鋁箔再用。</p><p style="text-indent:25px">螺旋硅碳棒表面負(fù)荷影響其使用壽命，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，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多度以上時熱端部位是不適宜用眼睛直視的。現(xiàn)實使用中也有用戶反映冷端發(fā)紅的現(xiàn)象，這個現(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)我們在對等直徑硅碳棒進(jìn)行工作使用的時候，了解了這些方向之后我們在處理的時候才能更加的方便快捷。公司實力雄厚，產(chǎn)品質(zhì)量可靠。</p><div
