style="text-indent:25px">一般在制作硅碳棒時的次燒結，都是將碳化硅生料和瀝青、焦油等粘合劑攪拌均勻，并用擠壓機擠壓成型，然后在隧道窯中直接進行燒結，這種做法會有一定的缺點?，F(xiàn)在給大家介紹一下新的制作工藝。　　新的工藝在次燒結時是將擠壓成型的胚件，放在真空容器里，抽真空到20~50毫米汞柱，然后以每分鐘5~10攝氏度的升溫速度，從常溫升到350攝氏度，在350攝氏度保溫30分鐘，使胚件各部位均勻的達到此溫度，再以每分鐘10攝氏度的速度升溫至920攝氏度，在920攝氏度時保溫30分鐘，可以將殘留的摻合物雜質排清，得到較為理想的硅化碳燒結物。這種燒結方法在粗真空中進行，各種雜質成分易揮發(fā)，一次殘留的雜質少。　　第二次燒結式的原理是在碳化硅胚料的周圍用碳化硅粉末包圍起來，圍用其他埋料，這樣在高溫時不*形成還原性氣氛，而且使碳化硅胚料表面與新生成的碳化硅分子隔離開來，隔離物是碳化硅埋料，新生成的碳化硅分子與碳化硅埋料起作用，而保護了里面的碳化硅。　　新的工藝簡單操作而且將硅碳棒的雜質盡可能的減少，提高了產(chǎn)品的性能。同時在質量上又是一個新的提升。提高了整體的品質與使用年限。</p><p

通過**近對市場的調查回訪我們發(fā)現(xiàn)，很多客戶對硅碳棒的分組依據(jù)還不是理解的很明白，小編就將查閱的相關資料與大家分享一下，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)，不怕上當受騙，希望對大家有所啟發(fā)與幫助。硅碳棒在成型和燒成過程中，由于加工條件、壓力、溫度的差別，同一外形尺寸的捧電阻值都不相同，在同一臺爐子上要求全部棒具有相同的電阻值，很準辦到。針對這種情況，只好在一定電壓下，把阻值不同的棒按―定的規(guī)律分組使用，以滿足供電電壓和發(fā)熱的要求。那么分組有什么依據(jù)呢？個考慮供電電壓：用電網(wǎng)電壓等級為單相380V、220V、ll0V。電壓越低，每組串聯(lián)的棒支數(shù)較少，使用越方便。有特殊要求的爐子，還可以配備調壓器。第二個是每一支棒的電阻：廠方在出廠時已在棒上標注出600X：時棒的實際電阻。如標注不清,可以自行測試。但無電阻值的棒不允許使用。三個是發(fā)熱要求：按遠紅外發(fā)熱規(guī)律，元件溫度必須在550?600°C間。硅碳棒表面負荷積發(fā)熱溫度有一定關系，只要控制表面負荷，即可保證元件的溫度，一般550?600°C時棒的表面負荷為?。奧翔硅碳生產(chǎn)的設備產(chǎn)品質量上乘。江蘇三相硅碳棒廠家直銷</p><p

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在質量，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)品質量，實際上，預壓過程就是一種預成型。江蘇三相硅碳棒廠家直銷</p><p
