style="text-indent:25px">硅鉬棒具有高抗氧化性，在高溫氣氛下，原件的表面生成一層致密的石英SIO2保護層以防止MOSI2繼續(xù)氧化。當元件溫度大于1700度、熔點1710度的SIO2保護層熔融，由于表面張力的作用，SIO2熔聚成滴，而失去保護作用。元件在氧化氣氛下在繼續(xù)使用時，SIO2保護層重新生成。硅碳棒用途:由于硅碳棒使用溫度高,具有耐高溫、抗氧化,耐腐蝕、升溫快、壽命長、高溫變形小、安裝維修方便等特點。有良好的化學穩(wěn)定性。若與自動化供電系統(tǒng)配套,既可得到精確的恒定溫度,又可根據(jù)生產(chǎn)工藝的實際需要按曲線自動調(diào)溫。現(xiàn)已廣泛應用于**、機械、冶金、輕化、陶瓷、半導體、分析化驗、科學研究等領域,成為各種電爐電窯的電加熱元件.隧道窯、輥道窯、玻璃窯爐、真空爐、馬弗爐、冶煉爐以及各類加熱設備,使用硅碳棒加熱既方便,又安全可靠。被普遍用于電子、磁性材料、粉末冶金、陶瓷、玻璃、冶金和機械等工業(yè)的多種高溫電爐，電窯。及其電加熱設備上．</p><p>N21500℃1600℃濕H21400℃1500℃干H21350℃1450℃1.硅鉬棒電氣性質(zhì)硅鉬棒元件的電阻率隨著溫度升高而快速增高（見下圖）在正常情況下，元件電阻一般不隨使用時間的長短而變化，所以新舊元件可以混合使用。2.硅鉬棒表面負荷根據(jù)爐子的結(jié)構(gòu)、氣氛和溫度正確的選擇元件的表面負荷是元件達到壽命的關鍵，下圖示出發(fā)熱元件輻射在不受阻礙情況下爐溫、元件溫度與表面負荷的關系，陰影部分為常用的表面負荷-----溫度范圍。硅鉬棒元件的安裝硅鉬棒元件在常溫下脆性較大，高溫時又有可塑性，所以U型棒是垂直懸掛安裝，若需水平安裝，請選用高溫耐火材料支撐，把硅鉬棒水平放置。元件圓錐部分一定要延伸到爐膛內(nèi)，硅鉬棒夾具不能一次擰的太緊，待元件升到高溫時，再次擰緊，這樣元件不易折斷，（建議：請選取用我公司配備的**夾具和導線），爐頂保溫性能要好，一般爐頂溫度不能超過300℃。夾頭導線與元件接觸電壓應低于，為避免幅射熱傳到夾頭，夾頭下端和塞磚上面的距離不應小于50mm。φ6元件不能長期使用170A，φ9元件不能長期使用300A。硅鉬棒爐子的操作新筑成的或長期不使用的爐子在使用前需要干燥，干燥溫度為100-200℃。大型爐子干燥時間長，使用其它發(fā)熱元件烘爐。奧翔硅碳銳意進取，持續(xù)創(chuàng)新為各行各業(yè)提供專業(yè)化服務。</p><div
