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，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，廣西螺旋硅碳棒廠家直銷，選定直徑和長度，計算出單支硅碳棒的發(fā)熱部表面積，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)，就是變壓器的選用，廣西螺旋硅碳棒廠家直銷，廣西螺旋硅碳棒廠家直銷，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。奧翔硅碳擁有業(yè)內(nèi)**人士和高技術人才。廣西螺旋硅碳棒廠家直銷</p><div

style="text-indent:25px">硅碳棒是高溫窯爐上的一種重要配件，它的耐高溫性能非常的強，因此，其應用范圍也在不斷的擴大，下面我們就隨廠家一起來看一下它在白熾燈中的應用吧：　　硅碳棒是簡便的紅外光源，作為光聲光譜用的光源，其想射束強度低1個數(shù)量級以上，為此，輸入功率更髙，并在高溫下工作的白熾碳棒被用作光聲光譜的光源，碳棒是在氬氣氛中通電的，可得到2500K左右的熱輻射分布溫度，棒的壽命是400小時左右，可以用光譜純的高純度碳制作，在直徑8亳米、長度120毫米的碳棒**，開有長度為6厘米、深度為3毫米的V形槽，以此作為熱輻射區(qū)，所需功率約為4千瓦，電極部分用水冷卻，腔罩用溴化鉀光窗，這樣更容易輸出熱輻射，蒸發(fā)的碳一旦附著在腔罩上，便會引起電流的損失，導致光源變暗，因此，必須定期淸洗腔罩。廣西螺旋硅碳棒廠家直銷奧翔硅碳不懈追求產(chǎn)品質(zhì)量，精益求精不斷升級。</p><div

style="text-indent:25px">我們平時在使用等直徑硅碳棒的時候，會根據(jù)使用的環(huán)境以及所做工作去計算它的使用功率，大家知道熱量與功率之間的關系嗎，下面來看下。　　等直徑硅碳棒熱量、功率基本關系　　W(瓦)=J/S（焦耳/秒） 1 kw=1 kj/s=3600 kj/h 　　1千卡=1大卡=1000卡(cal)=1000卡路里=4184j=4.184kj 　　二、水蒸氣換算　　利用軟件，狀態(tài)參數(shù)填好壓力、溫度兩個參數(shù)，查詢方式選擇已知P和T，點擊確定，可以獲得該參數(shù)蒸汽的焓值。以9.81 540℃為例，查詢焓值為3477kj/kg 　　1t/h蒸汽熱量=1000kg/h蒸汽熱量=1000kg/h*3477 　　kj/kg=3477*103kj/h=3477*103 　　kj/h÷3600（kj/h）/kw=965.8kw 　　但是對于熱水鍋爐，有常用的系數(shù)。即1MW=1.4t/h（或者1t=0.7MW）　　</p><p style="text-indent:25px">碳硅棒按照直徑來區(qū)分的話主要可以分為粗端部和等直徑兩種類型，它們區(qū)別明顯的地方在于：相同規(guī)格下，等直徑的比粗端部的功率大，使用時間長，耐腐蝕性強，那么對于等直徑硅碳棒如何把握它的連接方式呢？　　在安裝供電設備選用調(diào)壓范圍較大可平穩(wěn)連續(xù)調(diào)壓的設備，如磁性調(diào)壓器，可控硅交直流調(diào)壓器等，如選用有級調(diào)壓變壓器，也應選用電壓級差小，調(diào)壓擋數(shù)多的變壓器，硅碳棒元件的聯(lián)結方式可以是串聯(lián)也可以是并聯(lián)，一般情況下以并聯(lián)使用作為優(yōu)先選擇，而且在串聯(lián)使用時，支路串聯(lián)支數(shù)不宜多于3支。　　其實在使用的時候不只是要關注等直徑硅碳棒的連接方式，當焊接生成物在1500度高溫下化學性能穩(wěn)定，抗彎強度達到了600KGCM2，這時硅碳棒冷端與發(fā)熱部的單位長度電阻之比由1：6提高到1：24以上，使使用壽命明顯提高，所以它的使用環(huán)境也是需要注意的。奧翔硅碳設備的引進更加豐富了公司的設備品種，為用戶提供了更多的選擇空間。</p><div

style="text-indent:25px">　選用硅碳棒的時候，我們都需要了解產(chǎn)品的理化性質(zhì)，這樣在后期進行使用的時候才能方便選用，下面來看下硅碳棒的理化性質(zhì)。　　元件質(zhì)地：硬而脆，耐急冷急熱，高溫下不易變形，其它物理性能如下：　　導熱系數(shù)：**卡/米·小時·度　　線膨脹系數(shù)：5×10-6(m/℃) 　　化學性質(zhì)：有良好的化學穩(wěn)定性，抗酸能力強。在高溫條件下堿性物質(zhì)對其有侵蝕作用。　　硅碳棒元件在1000℃以上長期使用能與氧氣和水蒸氣發(fā)生如下作用：　?、賁ic+2O2→Sio2+CO2 ②Sic+4H2O=Sio2+4H2+CO2 　　致使元件中SiO2含量逐漸增多，電阻隨之緩慢增加，為之老化。如水蒸氣過多，會促進SiC氧化，由②式反應產(chǎn)生的H2與空氣中的O2結合H2O再反應產(chǎn)生惡性循環(huán)。降低元件壽命。氫氣　　(H2)能使元件機械強度降低。氮氣(N2)在1200℃以下能防止SiC氧化1350℃以上與SiC發(fā)生反應，使SiC分解氯氣(Cl2)能使Sic完全分解。奧翔硅碳累積點滴改進，邁向優(yōu)良品質(zhì)！廣西螺旋硅碳棒廠家直銷</p><p

style="text-indent:25px">　等直徑硅碳棒的使用時的準備事項，在安裝在不同的使用位置時要特別注意做好前期的準備工作，這個樣有利于棒延長使用壽命，發(fā)揮棒的價值。　　1、新爐或久未使用的電爐，在使用之前必須烘爐，烘爐時盡可能用舊棒或其它熱源。　　2、注意防止等直徑硅碳棒負荷使用，如棒因故斷裂或發(fā)現(xiàn)棒發(fā)熱不均，局部呈白熾或暗紅現(xiàn)象一段一段時，這說明棒體老化不一致，一段段電阻相差太大，應停爐檢修換棒，全部更換新棒，如更換部分新棒或單支棒時會因新棒電阻與舊棒的電阻匹配不合適，導致負荷不平衡，爐溫不均勻。因電阻差異大，故棒溫高低相關也打，會嚴重影響使用壽命。　　3、如果燒制器件時，在加熱過程中有水分排出，所用電阻爐（窯）要留有排氣孔，以便排除爐（窯）內(nèi)的水份或其它廢氣，以免影響等直徑硅碳棒的使用壽命。　　4、等直徑硅碳棒的存放過程中，要注意防潮，如發(fā)現(xiàn)棒端噴鋁處變質(zhì)潮解，經(jīng)表面處理后可重新噴鋁，如無噴鋁條件，可在棒噴鋁段纏裹幾層鋁箔即可。　　5、等直徑硅碳棒安裝使用前先檢查冷端部標記的電阻（Ω）值，如字跡不清，須重新測試，測試方法是將硅碳棒通電加熱升溫至1050℃的高溫時測得的電壓，電流，以歐姆定律求的電阻。廣西螺旋硅碳棒廠家直銷</p><p
