通過這一段時間的了解，相信大家對硅碳棒已經(jīng)是不陌生了，但對于想進一步了解本產(chǎn)品的相關知識的客戶來說這些內(nèi)容還是不夠的。小編就將關于硅碳棒的選擇原則方面的知識與大家分享一下，希望引起大家的重視，U型硅碳棒，讓大家對硅碳棒有一個深層次的了解。這樣大家在購買使用硅碳棒時也能做到心中有數(shù)，不慌不忙，希望對大家有所啟發(fā)與幫助。選用硅碳棒的幾個原則有：爐功率計算、發(fā)熱部總表面積計算、硅碳棒支數(shù)的計算、變壓器的選用，一般電爐的功率視爐子保溫性能而定，保溫好的電爐升溫時間和散熱時間要就一些，發(fā)熱面積的計算就是爐用功率和發(fā)熱部表面負荷，根據(jù)所有設計電爐的各部位尺寸和發(fā)熱部總表面積，從硅碳棒尺寸表中查出所需規(guī)格，選定直徑和長度，計算出單支硅碳棒的發(fā)熱部表面積，U型硅碳棒，用所需發(fā)熱部總面積除以單支硅碳棒的發(fā)熱部表面積，就可以求得所需支數(shù)，如果在三相電路中，選用總為3的倍數(shù)，單相電路中應為2的倍數(shù)，U型硅碳棒，就是變壓器的選用，硅碳棒的接線方式和變壓器的選擇對其使用壽命有重要的影響，以上所述基本是硅碳棒廠在考量及選用硅碳棒時比較注意的幾點。奧翔硅碳在客戶和行業(yè)中樹立了良好的企業(yè)形象。U型硅碳棒</p><div

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。二氧化硅薄膜在結晶臨界點（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，所以反復破二氧化硅薄膜，加速氧化。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荷較集中，易導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)接線結合使用。建議采用2根串聯(lián)為一組后多組并聯(lián)。特別當爐內(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。硅碳棒經(jīng)銷商奧翔硅碳累積點滴改進，邁向優(yōu)良品質(zhì)！</p><div

**近很多客戶聯(lián)系我們，把他們在硅碳棒的使用過程中遇到的問題向我們請教，希望我們能給予幫助，小編就這些問題中的關于硅碳棒電阻值方面的知識與大家共同探討一下，希望能給廣大客戶朋友們帶來啟發(fā)與幫助，讓大家對硅碳棒有一個深層次的了解。這樣大家在以后使用過程中時也能做到心中有數(shù)，不慌不忙，發(fā)揮出硅碳棒的比較大作用。大家在使用硅碳棒的時候有時會遇到需要硅碳棒串聯(lián)的情況，那就需要挑選合適的硅碳棒進行串聯(lián)。一般硅碳棒廠家會告訴用戶使用電阻值相近的棒進行串聯(lián)，這個電阻值指的是硅碳棒單位長度的電阻值，一般以Ω/m為單位。一般硅碳棒測電阻測的都是單位長度的電阻值。那么串聯(lián)時跟長度與粗細有沒有關系呢？為什么是單位電阻值而不是整根的電阻值？把兩根硅碳棒視作兩個電阻元件，不應該是整體電阻相似所以分壓一樣嗎?硅碳棒不同于一般的電阻元件，一般的電阻元件由于體積小，發(fā)熱小，所以忽視長度跟粗細帶來的影響。硅碳棒相比一般的電阻元件長度大得多，并且主要利用的是發(fā)熱而不是電阻的大小，所以串聯(lián)時就不能忽視體積的因素。比如說一根直徑20，長度100的棒跟直徑40長度200的棒，假如說兩根棒的電阻一樣，那么即使電阻一樣也不能串聯(lián)。</p><p style="text-indent:25px">有些小細節(jié)可能不注意就會造成嚴重的后果，損壞等直徑硅碳棒的本質(zhì)，接下來介紹的這十個方面如果能夠很好的注意到就可以更好的發(fā)揮棒的價值。　　一、等直徑硅碳棒硬而脆，在運輸、開箱、安裝更換時要特別小心，輕拿、輕放、嚴防機械敲打，以免斷棒。　　二、新爐開始送電時，為了防止斷棒，應采用電爐額定功率的1/2空送一段時間，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、當棒穿過爐壁兩側（或上下）的棒孔后，應自由轉(zhuǎn)動360度，嚴防嚴格安裝與敲打，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，應提高使用電壓，當電壓提高到所用電壓器高限度仍不能滿足要求時，可停爐改變棒的接線方式在繼續(xù)使用。　　五、棒使用時每組棒應進行高溫阻值配阻，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 。奧翔硅碳以創(chuàng)百年企業(yè)、樹百年品牌為使命，傾力為客戶創(chuàng)造更大利益！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="U型硅碳棒,硅碳棒"

style="text-indent:25px">硅碳棒廠家在制作硅碳棒的過程中，通常采用以瀝青做結合劑的擠壓成型，這個預壓的工藝會直接影響到硅碳棒的外觀和內(nèi)在質(zhì)量，那么它是如何操作的呢？　　硅碳棒坯料經(jīng)對輥對壓后，運轉(zhuǎn)到液壓機處，須經(jīng)過反復幾次的模型擠壓，又稱二次預壓，它是在200~500t油壓機上進行的，其中輔助設備有63t油壓機，加熱保溫箱，模筒，模嘴，中心針，固定中心針的三角架，電感線圈和單相調(diào)壓器等。　　根據(jù)硅碳棒廠家生產(chǎn)條件、生產(chǎn)規(guī)模差異的影響，選用的油壓機噸位也不一樣，比如以400t油壓機為例，二次預壓的坯料必須是經(jīng)加熱料鍋預熱的坯料，直徑大于8mm的發(fā)熱體坯料需預壓3遍，直徑小于8mm的發(fā)熱體坯料和端部料需預壓兩遍。　　遍預壓時，由于坯料松散，擠壓困難，故應選擇出口直徑大點的嘴子，一般為50mm左右，之后幾遍可選用出口直徑小一點的嘴子，同時配用適當?shù)闹行尼樦睆?，每次從模嘴擠出的料應馬上運到63t油壓機上壓成坯塊，然后投放到暖料鍋中保溫，準備成型。　　其實硅碳棒廠家進行預壓的目的是進一步使坯料混合，排出氣體，增加密度，這樣不但有利于成型，還可以提高產(chǎn)品質(zhì)量，實際上，預壓過程就是一種預成型。奧翔硅碳重信譽、守合同，嚴把產(chǎn)品質(zhì)量關，熱誠歡迎廣大用戶前來咨詢考察，洽談業(yè)務！U型硅碳棒</p><p
