等直徑硅碳棒“老化”的原因是什么呢？1小編就為大家介紹一下硅碳棒的“老化”。硅碳棒是由于在高溫下,空氣中的o2、co2和水蒸汽能強(qiáng)烈地促使砝碳櫸氧化，生成玻璃態(tài)的Sio2薄膜，廣西單螺旋硅碳管批發(fā)，而Si02的電阻率較SiC電PU率大，故使電阻增加。又因?yàn)檫@層SiO,薄暌可以保護(hù)內(nèi)層的Sic不再繼續(xù)氧化，所以在連續(xù)使用一定時(shí)間后，電阻的增加將緩慢下來。在間歇使用時(shí)，由干sio2薄膜與SiC的熱膨脹系數(shù)不同，當(dāng)砝碳棒冷卻時(shí)，這層玻璃態(tài)薄膜即行破裂而暴露出新的Sic表面。當(dāng)繼續(xù)加熱時(shí)，這些新露出的SiC表面又繼續(xù)被氧化，經(jīng)過多次加熱、冷卻之后丨珪碳棒的電阻越來越大，終千大到不能再使用了。1、幾何尺寸的選擇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相應(yīng)確定下來，現(xiàn)舉例說明如下：如被加熱物是?70×500mm的石英管（這里的500mm是指石英管的受熱區(qū)，實(shí)際上石英管還要長）則硅碳管的規(guī)格可選用?90/80×500/100，廣西單螺旋硅碳管批發(fā)，二爐膛的高鋁管則可選用其內(nèi)徑為100mm，其長度要略長于500mm。2、硅碳棒保護(hù)管使用的功率硅碳管使用的功率決定于爐子的保溫條件，廣西單螺旋硅碳管批發(fā)，幾何尺寸及到達(dá)的溫度。對于較好的保溫條件，恒溫后，硅碳管發(fā)熱區(qū)內(nèi)表面的溫度與被加熱物的溫度相差≦50℃。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！廣西單螺旋硅碳管批發(fā)</p><div

給硅碳棒加的電流量越大，硅碳棒的表面溫度越高。建議使用盡量小的表面負(fù)荷密度（功率）。請注意硅碳棒冷端記載的數(shù)值為空氣中1050℃的電流、電壓，與實(shí)際使用不一定相符。一般情況下，硅碳棒表面功率是由爐內(nèi)溫度和硅碳棒表面溫度的關(guān)系求得，建議使用硅碳棒極限密度的1/2-1/3數(shù)值的表面功率（W/cm2）連續(xù)使用硅碳棒時(shí)，希望緩速增加電壓以維持長壽命。硅碳棒盡可能并聯(lián)。如果硅碳棒阻值不同，串聯(lián)時(shí)電阻高的硅碳棒負(fù)荷集中，導(dǎo)致某一個(gè)硅碳棒電阻快速增加，壽命變短硅碳棒的溫度分布特性，新出貨時(shí)的檢查規(guī)格為在有效長度內(nèi)為1500度內(nèi)為才算合格，當(dāng)溫度分布會(huì)隨著其電阻的老化而變小，具體溫度分布變化也因爐內(nèi)氣氛、使用條件的不同而不同。硅碳棒隨著使用溫度越高壽命為越短，因此在爐膛溫度超1600℃以后，氧化速度加快，壽命縮短。廣西單螺旋硅碳管批發(fā)奧翔硅碳交通便利，地理位置優(yōu)越。</p><div

硅碳棒、硅碳管是用高精度碳化硅（SIC）為主要原料、經(jīng)高溫（2200℃）再結(jié)晶制成的非金屬電熱元件。使用比較高溫度1600℃，正常使用溫度1450攝氏度，連續(xù)使用壽命可達(dá)3000小時(shí)以上。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(diǎn)，且有良好的化學(xué)穩(wěn)定性。硅碳棒、硅碳管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(dāng)理想的溫區(qū)。該產(chǎn)品用于灰分熔點(diǎn)測定儀，煤炭活性測定儀，雙管定硫儀，膠質(zhì)層（Y值）等。硅碳棒使用的注意事項(xiàng)：（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，偏差不超出10%，如果個(gè)別電流太大就說明阻值太小。如果電流太小，不是阻值太大就是管腳按觸不良。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。</p><p> 產(chǎn)品結(jié)構(gòu)本系列電爐外殼由鋼板卷制焊接而成，爐膛管采用耐高溫的氧化鋁制成。發(fā)熱元件為硅碳管，其外套有隔熱高鋁管，爐膛襯有絕熱良好的保溫材料。由于選用雙螺紋一端接線的硅碳管，與工作電源連接比較整齊方便，熱電偶也從此端插入。四、使用注意事項(xiàng)1、硅碳管質(zhì)地硬而脆，螺紋帶彈性有限，安裝拆卸時(shí)應(yīng)充分小心注意，以免折斷，碰壞。在任何情況下應(yīng)保證它自由膨脹和收縮，應(yīng)避免機(jī)械應(yīng)力的存在。2、硅碳管的老化、壽命與使用溫度關(guān)系很大，一般在1300℃±50℃能運(yùn)行1500作業(yè)小時(shí)左右。3、被加熱物不能含有過高的水分，否則會(huì)影響硅碳管的壽命，可以烘干以后再加熱。4、硅碳管不適應(yīng)在保護(hù)氣氛下工作，例如氫氣。一氧化碳在供氧不足的情況下也會(huì)使碳游離，從而影響硅碳管的壽命。5、硅碳管的表面負(fù)荷的選用隨溫度而變化，工作溫度在1300℃時(shí)允許6w/cm2，而工作溫度在1000℃時(shí)可允許30w/cm2，選擇合適的加熱功率可以延長硅碳管的壽命。6、硅碳管安裝之前應(yīng)將內(nèi)外爐管之間打掃干凈。硅碳管螺紋帶之間或能引起短路的雜物，導(dǎo)電卡子連接片應(yīng)旋緊接實(shí)，絕緣片應(yīng)可靠絕緣。7、安裝完畢即可通電烘爐，由低溫小功率開始進(jìn)行8小時(shí)，長期不用使用前也必須烘爐，尤其是南方潮濕地區(qū)。奧翔硅碳以誠信為根本，以質(zhì)量服務(wù)求生存。</p><div

1、現(xiàn)在對污染物做到了回收利用，環(huán)境也有了明顯的改變。2、目前等直徑硅碳棒的生產(chǎn)工藝有兩種，老工藝與新工藝，區(qū)別方法在與燒制方面。3、從燒結(jié)方式上講它有兩種制作工藝：老工藝與新工藝。4、老工藝采用的是埋藏反應(yīng)燒結(jié)，新工藝采用的是高溫真空爐燒結(jié)。5、由于埋藏?zé)菩枰妹海瑢Νh(huán)境有一定的污染，好多都已取締，大多采用新工藝制作。6、比如在鋁廠，玻璃廠，釩氮合金，反光材料產(chǎn)品燒結(jié)中會(huì)產(chǎn)生一定的腐蝕氣體，老工藝比新工藝元件的耐腐蝕性要好。7、元件是很高的純度以碳化硅為主要原料，加入工業(yè)硅，碳粉等材料。經(jīng)過成型，烘干，高溫?zé)Y(jié)等多道工序而制成的一種非金屬棒狀高溫電熱元件。8、真空爐燒結(jié)的沒有埋藏法燒結(jié)的硅碳棒時(shí)間長，所以與其它材料不能完全的產(chǎn)生反應(yīng)，制作的元件在某些地方使用不能達(dá)到效果。奧翔硅碳具有一支經(jīng)驗(yàn)豐富、技術(shù)力量過硬的專業(yè)技術(shù)人才管理團(tuán)隊(duì)。天津?qū)I(yè)生產(chǎn)硅碳管經(jīng)銷商</p><p

等直徑硅碳棒的電阻值，跟著元件溫度的改變而改變，由于元件是一種非線性型電阻體。從室溫至850±50℃，電阻由大變??；850±50℃以上又由小變大。也就是說：元件的電阻溫度系數(shù)有負(fù)值期間也有正值期間。在棒的一端所標(biāo)電阻是按部頒標(biāo)準(zhǔn)規(guī)定在1050±50℃時(shí)測定的，便于裝置時(shí)調(diào)配。元件的表面負(fù)荷密度與爐子的溫度有密切關(guān)系,可以根據(jù)需要恣意調(diào)整。需要爐溫高時(shí)加大負(fù)荷密度,反之可降低負(fù)荷密度。即所謂“調(diào)功”。1、幾何尺寸的選擇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相應(yīng)確定下來，現(xiàn)舉例說明如下：如被加熱物是?70×500mm的石英管（這里的500mm是指石英管的受熱區(qū)，實(shí)際上石英管還要長）則硅碳管的規(guī)格可選用?90/80×500/100，二爐膛的高鋁管則可選用其內(nèi)徑為100mm，其長度要略長于500mm。2、硅碳棒保護(hù)管使用的功率硅碳管使用的功率決定于爐子的保溫條件，幾何尺寸及到達(dá)的溫度。對于較好的保溫條件，恒溫后，硅碳管發(fā)熱區(qū)內(nèi)表面的溫度與被加熱物的溫度相差≦50℃。我們可以利用下式先計(jì)算硅碳管發(fā)熱部單位表面積的負(fù)荷。廣西單螺旋硅碳管批發(fā)</p><p
