style="text-indent:25px">硅碳棒作為常用的一種工業(yè)零件，因?yàn)楸旧砭哂心透邷氐忍匦?，同時(shí)含有良好化學(xué)穩(wěn)定性。所以常被使用與各種的工業(yè)環(huán)境中，硅碳棒廠家一般在使用時(shí)，應(yīng)當(dāng)注意哪些。　　1、為了使每支硅碳棒都能處于正常而理想的工作狀態(tài)，安裝前對整批硅碳棒測定其電阻值，將其分類，電阻值相近的裝在同一調(diào)整區(qū)，使之工作電阻相近。　　2、為了檢驗(yàn)每支硅碳棒電熱元件是否良好工作，通電試驗(yàn)時(shí)可用鉗形電流表逐一測定電流。同一區(qū)域在相等的電壓下要求電流相近，偏差不多出10%，如果個(gè)別電流太大說明阻值太小，如果電流太小，不是阻值太大是管腳按觸不良，如果沒有電流可能是硅碳棒電熱元件已斷裂，應(yīng)進(jìn)一步檢查更換。　　3、硅碳棒電熱元件質(zhì)脆易斷，特別在帶螺紋位置脆弱，安裝要特別小心，輕拿輕放，安裝時(shí)要特別注意絕不允許單邊受力，必要時(shí)應(yīng)用耐熱鋼管套住硅碳棒輕輕推入然后拔出鋼管套，安上護(hù)套固定好。　　4、為防止硅碳棒電熱元件與上部結(jié)構(gòu)的耐火材料互相影響，各個(gè)元件的管腳均用陶瓷纖維套管絕緣，陶瓷纖維套管不但起著電氣絕緣的作用而且還起到固定硅碳棒的作用。　　5、在窯爐中使用硅碳棒，操作溫度可達(dá)1700℃，但在還原性氣氛下，操作溫度為1500℃，要注意溫度的控制。</p><p style="text-indent:25px">有些小細(xì)節(jié)可能不注意就會造成嚴(yán)重的后果，損壞等直徑硅碳棒的本質(zhì)，接下來介紹的這十個(gè)方面如果能夠很好的注意到就可以更好的發(fā)揮棒的價(jià)值。　　一、等直徑硅碳棒硬而脆，在運(yùn)輸、開箱、安裝更換時(shí)要特別小心，輕拿、輕放、嚴(yán)防機(jī)械敲打，以免斷棒。　　二、新爐開始送電時(shí)，為了防止斷棒，應(yīng)采用電爐額定功率的1/2空送一段時(shí)間，一切正常后再逐漸升高電壓，要按電爐升溫規(guī)范升溫，以免因功率過高炸斷等直徑硅碳棒。　　三、當(dāng)棒穿過爐壁兩側(cè)（或上下）的棒孔后，應(yīng)自由轉(zhuǎn)動360度，嚴(yán)防嚴(yán)格安裝與敲打，裝棒前可用與棒直徑的鐵管試裝。　　四、使用等直徑硅碳棒必須配置調(diào)壓器或可控硅調(diào)壓器及電壓、電流表和溫度自動控制儀表等。在使用過程中因棒氧化，電阻則逐漸增加，為保持爐溫正常，應(yīng)提高使用電壓，當(dāng)電壓提高到所用電壓器高限度仍不能滿足要求時(shí)，可停爐改變棒的接線方式在繼續(xù)使用。　　五、棒使用時(shí)每組棒應(yīng)進(jìn)行高溫阻值配阻，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 。奧翔硅碳累積點(diǎn)滴改進(jìn)，邁向優(yōu)良品質(zhì)！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="吉林大頭硅碳棒生產(chǎn)廠家,硅碳棒"

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(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，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1350℃時(shí)必須并聯(lián)。三相接線時(shí)建議使用開放三角形接線。奧翔硅碳生產(chǎn)的產(chǎn)品受到用戶的一致稱贊。吉林啞鈴硅碳棒生產(chǎn)廠家</p><p
