style="text-indent:25px">真空氣氛爐有著水冷裝置，真空氣氛爐的爐殼、爐蓋、電熱元件，分別處置(水冷電極)、中間真空隔熱門等部件，均在真空、受熱狀態(tài)下工作。在這種極為不利的條件下工作，必須保證各部件的結(jié)構(gòu)不變形、不損壞，真空密封圈不過熱、不燒毀。因此，各部件應(yīng)該根據(jù)不同的情況設(shè)置水冷裝置，以保證氣氛爐能夠正常運行并有足夠的使用壽命。真空氣氛爐采用低電壓大電流：在真空容器內(nèi)，當(dāng)真空空度為幾托一的范圍內(nèi)時，真空容器內(nèi)的通電導(dǎo)體在較高的電壓下，會產(chǎn)生輝光放電現(xiàn)象。在臺車爐內(nèi)，嚴(yán)重的會產(chǎn)生弧光放電，燒毀電熱元件、隔熱層等，造成重大事故和損失。因此，真空氣氛爐的電熱元件的工作電壓，一般都不超過80-100伏。同時在電熱元件結(jié)構(gòu)設(shè)計時要采取有效措施，如盡量避免有前列的部件，電極間的間距不能太小窄，以防止輝光放電或者弧光放電的發(fā)生。</p><p

style="text-indent:25px">在實際工作中，真空氣氛箱式爐、真空氣氛爐等爐型都可以看出傳熱過程很少是單一的傳熱方式,多數(shù)情況下是兩種或三種方式同時作用的綜合過程。1、傳導(dǎo)：傳導(dǎo)是指在無質(zhì)點相對位移的情況下，物體內(nèi)部具有不同溫度或不同溫度的物體直接接觸時所發(fā)生的熱能傳遞現(xiàn)象。在液體和非導(dǎo)電物體中，熱量的轉(zhuǎn)移是靠彈性波的作用；在金屬內(nèi)部則依靠自由電子的運動；在氣體中主要依靠原子或分子的擴散和碰撞。2、對流：對流是指由于流體的各部分相對位移而引起的熱量轉(zhuǎn)移。流體通過另一物體表面時所發(fā)生的熱交換稱為對流傳熱，包括物體表面附近層流層的傳導(dǎo)過程和層流層外的對流過程、因流體本身溫度和密度不同而引起的對流稱“自然流動”，而流體與表面間的傳熱稱“自然對流傳熱”；因外加各種機械力而產(chǎn)生的流動稱“強制流動”，而流體與表面間的傳熱則稱“強制對流傳熱”。3、輻射：輻射是一種由電磁波傳播熱能的過程。輻射傳熱不僅有能量的轉(zhuǎn)移，而且伴隨著能量形式的轉(zhuǎn)化，即熱能轉(zhuǎn)變成輻射能，輻射出的輻射能被吸收后又轉(zhuǎn)化為熱能。真空氣氛爐的爐子升溫后，不能突然破壞真空系統(tǒng)，更不可打開爐門。真空熱處理高溫氣氛爐制作</p><p style="text-indent:25px">真空熱處理爐與真空氣氛爐的應(yīng)用區(qū)別。真空熱處理高溫氣氛爐制作</p><p style="text-indent:25px">真空氣氛爐需要有嚴(yán)格的氣密性，因此該爐口也是關(guān)鍵組成部分之一。真空氣氛爐爐口采用不銹鋼循環(huán)水套形式，加熱使用過程需使用循環(huán)水，使?fàn)t門口溫度降低，并保證密封材料的不損壞，從而提高了設(shè)備的氣密性，要保證高溫硅膠墊處爐門溫度達(dá)到正常溫度即可。真空氣氛爐的升溫、送氣按規(guī)定烘爐工藝曲線進(jìn)行烘爐升溫；升溫同時打開爐頂風(fēng)扇的冷卻水套供水閥門，合上風(fēng)扇電源。當(dāng)爐溫達(dá)高溫以上時，向爐內(nèi)送入吸熱氣氛；真空氣氛爐中的保護(hù)氣氛爐中釬焊，其原理是：加有釬料的焊件在還原性氣氛或惰性氣氛的電爐中加熱進(jìn)行釬焊，主要適用于釬焊碳素鋼、合金鋼、硬質(zhì)合金、高溫合金等。真空熱處理高溫氣氛爐制作</p></p><br
