爐襯材料應(yīng)用剛玉磚，其Fe2O3的質(zhì)量分數(shù)應(yīng)小于1%，因為它與保護膜相互作用形成易熔的硅酸鹽，從而加速元件的破壞。　　2)冷端部泄漏的熾熱爐氣，不僅增加爐子的熱損失，甚至會燒壞導電帶夾頭和引線夾子，因此，比較好采用石棉夾頭。　　3)因硅鉬棒是脆性材料，抗彎強度低，不能承受碰擊，在安裝過程中應(yīng)采取防護措施，以防折斷。連接導電帶時，必須先將石棉夾頭(或瓷夾頭)安裝好，夾緊時用力不能過大。　　4)將硅鉬棒裝進塞磚，為了避免因裝卸移動而產(chǎn)生的機械應(yīng)力，塞磚要用泡沫剛玉磚制成的單獨磚塊。　　5)將裝有硅鉬棒的塞磚插入爐頂準備好的空檔中,塞磚要突出于爐頂?shù)耐饷?，這樣便于拆卸。　　6)將導電帶同早已準備好的連接支架相連接，但應(yīng)避免導電帶緊張和不自然的扭曲機械應(yīng)力。　　7)為了避免石棉夾頭因熱脹冷縮而可能使硅鉬棒下垂變形，可用水玻璃拌合的耐火泥漿涂在連接處，以便固定牢靠。　　8)吊裝時發(fā)熱部的錐體交界處與爐墻相距約25mm-3omm，冷端部應(yīng)露出爐頂外面75mm，其發(fā)熱部的下端到爐底應(yīng)不小于50mm。　　9)硅鉬棒在爐內(nèi)的間隔應(yīng)不小于元件本身的中心間距。 </p><p> 硅碳棒在生產(chǎn)的時候，結(jié)合劑使用的種類不同造成工藝不同。一般國內(nèi)硅碳棒生產(chǎn)廠家使用的結(jié)合劑有瀝青結(jié)合劑和樹脂結(jié)合劑。使用瀝青結(jié)合劑和樹脂結(jié)合劑各有各的優(yōu)勢。下面來講一下瀝青結(jié)合劑的特點。瀝青結(jié)合劑是煤焦油或者石油經(jīng)過蒸餾或者催化裂化提取沸點不同的殘留物，是一種黑色的混合物。瀝青結(jié)合劑在耐火材料行業(yè)有著普遍的應(yīng)用，應(yīng)用于高爐爐缸的鋁鎂碳磚、碳磚、鋁-碳磚、轉(zhuǎn)爐和電爐、爐外精煉爐用的鎂-碳磚、硅碳棒等。在耐火材料行業(yè)按軟化點分類可分為低溫瀝青中溫瀝青和高溫瀝青。瀝青是一種混合物，瀝青的成分有很多物質(zhì)，一般都是碳氫氧化合物，還摻雜有硫化合物和氮化合物等，含碳量比較高，所以高溫元件含碳產(chǎn)品用到的比較多，比如說硅碳棒。瀝青結(jié)合劑作為硅碳棒的結(jié)合劑，其中碳含量越高，揮發(fā)物質(zhì)越少越好。碳含量越高則結(jié)合力越強。瀝青結(jié)合劑在硅碳棒使用中有高溫可塑性好，低溫成型能力好的特點，但是相對于樹脂結(jié)合劑，使用瀝青結(jié)合劑的生產(chǎn)工藝相對來說要復雜一些。奧翔硅碳從國內(nèi)外引進了一大批先進的設(shè)備，實現(xiàn)了工程設(shè)備的現(xiàn)代化。</p><div
