style="text-indent:25px">一般在制作硅碳棒時(shí)的次燒結(jié)，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(jī)擠壓成型，然后在隧道窯中直接進(jìn)行燒結(jié)，這種做法會有一定的缺點(diǎn)?，F(xiàn)在給大家介紹一下新的制作工藝。　　新的工藝在次燒結(jié)時(shí)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(dá)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(shí)保溫30分鐘，可以將殘留的摻合物雜質(zhì)排清，得到較為理想的硅化碳燒結(jié)物。這種燒結(jié)方法在粗真空中進(jìn)行，各種雜質(zhì)成分易揮發(fā)，一次殘留的雜質(zhì)少。　　第二次燒結(jié)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(shí)不僅形成還原性氣氛，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(hù)了里面的碳化硅。　　新的工藝簡單操作而且將硅碳棒的雜質(zhì)盡可能的減少，提高了產(chǎn)品的性能。同時(shí)在質(zhì)量上又是一個(gè)新的提升。提高了整體的品質(zhì)與使用年限。</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(jié)合劑的擠壓成型，這個(gè)預(yù)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(yùn)轉(zhuǎn)到液壓機(jī)處，須經(jīng)過反復(fù)幾次的模型擠壓，又稱二次預(yù)壓，它是在200~500t油壓機(jī)上進(jìn)行的，其中輔助設(shè)備有63t油壓機(jī)，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(jī)噸位也不一樣，比如以400t油壓機(jī)為例，二次預(yù)壓的坯料必須是經(jīng)加熱料鍋預(yù)熱的坯料，直徑大于8mm的發(fā)熱體坯料需預(yù)壓3遍，直徑小于8mm的發(fā)熱體坯料和端部料需預(yù)壓兩遍。　　遍預(yù)壓時(shí)，由于坯料松散，擠壓困難，故應(yīng)選擇出口直徑大點(diǎn)的嘴子，一般為50mm左右，之后幾遍可選用出口直徑小一點(diǎn)的嘴子，同時(shí)配用適當(dāng)?shù)闹行尼樦睆?，每次從模嘴擠出的料應(yīng)馬上運(yùn)到63t油壓機(jī)上壓成坯塊，然后投放到暖料鍋中保溫，準(zhǔn)備成型。　　其實(shí)硅碳棒廠家進(jìn)行預(yù)壓的目的是進(jìn)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(shí)際上，預(yù)壓過程就是一種預(yù)成型。奧翔硅碳銳意進(jìn)取，持續(xù)創(chuàng)新為各行各業(yè)提供專業(yè)化服務(wù)。</p><div
