style="text-indent:25px">為了控制真空氣氛爐內(nèi)的氣氛，維持爐內(nèi)的壓力，爐內(nèi)工作空間始終要與外界空氣隔絕，盡量避免漏氣和吸入空氣，故要求爐殼，砌體，爐門及所有外界連接零件如風(fēng)扇，熱電偶，輻射管，推拉料機(jī)等采用密封裝置。要維持爐內(nèi)的一定碳勢(shì)，除了控制氣氛成分的穩(wěn)定性外，還要對(duì)爐內(nèi)氣氛進(jìn)行自動(dòng)控制。因此，需要設(shè)有各種控制儀表，以便對(duì)爐內(nèi)氣氛連續(xù)或定期測(cè)定并調(diào)整爐內(nèi)的供氣量。另外，保證氣氛爐氣氛的穩(wěn)定性，可分為馬弗爐和無(wú)馬弗爐兩種。馬弗爐的火焰在馬弗外，工件在馬弗內(nèi)進(jìn)行間接加熱；無(wú)馬弗爐采用各種火焰輻射管或者電輻射管，將火焰或者電熱體與爐氣隔開，以免破環(huán)爐內(nèi)氣氛的穩(wěn)定。</p><p style="text-indent:25px">眾所周知，真空氣氛爐加熱時(shí)爐管兩端要堵上隔熱塞，因?yàn)檎婵諝夥諣t的爐管兩端溫度較高，法蘭里無(wú)法承受較高的溫度，會(huì)讓爐子得氣密性不好，如果真空氣氛爐放入爐塞與爐子的兩端有利于形成均衡的溫場(chǎng)。真空氣氛爐的均勻性在±1度，決定真空氣氛爐的溫度是否能達(dá)到高溫，真空氣氛爐的爐溫穩(wěn)定性指：在爐內(nèi)同一位置不同時(shí)間內(nèi)溫度的波動(dòng)情況；真空氣氛爐的爐溫的均勻性是指：在同一時(shí)間內(nèi)，爐內(nèi)不同位置的溫度波動(dòng)情況，由于現(xiàn)在控溫儀表技術(shù)的提高，真空氣氛爐的爐溫穩(wěn)定度一般變化不大，我們通常是檢測(cè)爐溫的均衡度。真空氣氛爐就是可以抽真空又可以通氣氛的爐型，它有箱式、管式爐、升降爐等很多種不同爐型。</p><div
