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，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，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。福建單螺旋硅碳棒夾子奧翔硅碳愿和各界朋友真誠合作一同開拓。</p><div

style="text-indent:25px">螺旋硅碳棒在使用過程中雖然氧化緩慢，但長時間運行仍然會導致電阻值增大，這種現(xiàn)象叫做老化，為了減緩老化速度，我們對該碳棒做了一些性能：　　1、螺旋硅碳棒的紅外輻射率高，是普通鎳鉻絲的5-10倍。　　2、高表面溫度可達1500度。　　3、使用壽命長，安裝、維修簡單。　　4、螺旋硅碳棒的抗氧化性強，耐腐蝕性強，并具有優(yōu)良的耐熱沖擊性能。　　5、機械強度高，抗彎曲強度高達100-120MPa。　　在螺旋硅碳棒的制作過程中以獨特的技術，在發(fā)熱部得表面涂上了保護層，明顯的增強了元件的抗氧化性能，延長了使用壽命。</p><p style="text-indent:25px">螺旋硅碳棒不**是在加熱爐里使用，而且也可以是測硫儀**硅碳管，主要用于灰分熔點測定儀，煤炭活性測定儀，雙管定硫儀，膠質層（Y值）等，我們都知道的是以高純度SiC為主要原料，經(jīng)高溫再結晶制成的一種新型管狀電熱元件。　　螺旋硅碳棒做為管狀電熱元件來講，是一種很理想的產(chǎn)品，它不但比鎳鉻絲電熱元件使用的溫度高、壽命長，而且發(fā)熱均勻，升溫快，可以節(jié)約電能，并可取得相當理想的溫區(qū)，如果配制適當容量的調壓變壓器，它可以達到你需要的理想溫度，電爐的爐膛是由被加熱物的尺寸推算而決定，因而硅碳管的尺寸也可以根據(jù)它來確定下來。　　比如被加熱物是φ70×500mm的石英管，則螺旋硅碳棒的規(guī)格可選用φ90/80×500/100，而爐膛的高鋁管則可選用其內(nèi)徑位100mm，其長度要略長于500mm。　　所以螺旋硅碳棒用作電熱元件是一個越來越被認可的材料，需要注意的就是要做好使用前的選型，保證它的使用效果。奧翔硅碳從國內(nèi)外引進了一大批先進的設備，實現(xiàn)了工程設備的現(xiàn)代化。</p><div

style="text-indent:25px">螺旋硅碳棒斷了，如果是焊接處和不發(fā)熱的冷端斷裂，可以返回生產(chǎn)廠家，用**設備進行焊接，不影響使用效果。如果是螺旋硅碳棒的中間發(fā)熱體斷裂，不能用了，對于發(fā)熱體尺寸比較長的，也可以返廠焊接，但對爐溫有一定的影響，因為在返廠修復后，斷裂處有近100毫米的長度不發(fā)熱了。　　熱處理爐內(nèi)的非金屬加熱元件多為石墨棒或螺旋硅碳棒（管、棒、套）等，常用于高溫真空爐內(nèi)，其呈周向排列，由于它們脆性大，加熱時燒損等會易損壞或折斷，當一端折斷而又暫時無法或無條件整體更換，可用廢舊的螺旋硅碳棒研磨成粉后，用水玻璃調和成團面狀黏結劑，將折斷的螺旋硅碳棒在原位置固定好，在折斷部位的四周培一周。起爐升溫后折斷部位則會自行燒結在一起，其強度與基體相當。奧翔硅碳嚴格控制原材料的選取與生產(chǎn)工藝的每個環(huán)節(jié)，保證產(chǎn)品質量不出問題。福建雙螺旋硅碳棒生產(chǎn)廠家</p><p

**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)。福建螺旋硅碳棒電阻</p><p
