style="text-indent:25px">我們平時(shí)使用的硅碳棒的比較穩(wěn)定的性能，所以在加熱爐上是經(jīng)常使用的一種零件，那么在使用的時(shí)候需要注意的細(xì)節(jié)有那些呢？　　1、穿硅碳棒的爐孔的內(nèi)徑應(yīng)是冷端部外徑的1.4~1.6倍，爐孔過(guò)小或孔內(nèi)得填充物塞得過(guò)緊，高溫時(shí)阻礙自由伸縮而導(dǎo)致斷棒。安裝時(shí)，當(dāng)棒穿過(guò)爐壁兩側(cè)（或上下）的棒孔后，應(yīng)自由轉(zhuǎn)動(dòng)360度，嚴(yán)防安裝與敲打。　　2、硅碳棒與被加熱物及爐壁的距離應(yīng)大于或等于發(fā)熱部直徑的3倍。棒與棒之間的中心距應(yīng)不小于其發(fā)熱部直徑的4倍，冷端部與主電路用鋁辮或鋁箔連接且冷端部的夾具要卡緊。　　3、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。　　4、硅碳棒使用時(shí)每組棒應(yīng)進(jìn)行高溫阻值配阻。先阻值相同或接近連接在一起，配阻的電值允許差為：≥φ12mm棒配阻，電阻值允差為≤0.2Ω，≤φ8mm棒配阻，電阻值允差為≤0.5Ω。　　5、新建爐或長(zhǎng)時(shí)間不使用的在使用前要進(jìn)行烘爐，應(yīng)采用舊棒或其它熱源烘爐。開(kāi)始送電時(shí)，送電初期電壓應(yīng)為其正常工作電壓的一半，穩(wěn)定一段時(shí)間以后再逐漸提高電壓。　</p><p 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(zhǎng)。硅碳棒在使用中表面氧化生成二氧化硅薄膜，長(zhǎng)時(shí)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(dòng)，所以反復(fù)破二氧化硅薄膜，加速氧化。因此停電爐溫降至室溫時(shí)經(jīng)常急劇增加電阻。如果硅碳棒阻值不同，串聯(lián)時(shí)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)。特別當(dāng)爐內(nèi)溫度超過(guò)1350℃時(shí)必須并聯(lián)。三相接線時(shí)建議使用開(kāi)放三角形接線。奧翔硅碳技術(shù)力量雄厚，工裝設(shè)備和檢測(cè)儀器齊備，檢驗(yàn)與實(shí)驗(yàn)手段完善。</p><div
