style="text-indent:25px">較近有很多關(guān)注熱處理的朋友在問一個(gè)問題，就是能否使用現(xiàn)有真空爐進(jìn)行3D打印熱處理？根據(jù)資料顯示這也是要分情況而言，大多數(shù)真空爐都可以調(diào)整以執(zhí)行應(yīng)力消除或時(shí)效工藝。如果所需工藝溫度在爐子本身的溫度范圍內(nèi)，就沒有問題。在粘結(jié)劑噴射技術(shù)和燒結(jié)工藝方面，情況就復(fù)雜了。粘合劑在熱處理過程中產(chǎn)生蒸汽，這些蒸汽可能積聚在爐體溫度較低的部分、泵送系統(tǒng)或電源饋通上，這會(huì)降低爐子某些部件的壽命，甚至導(dǎo)致嚴(yán)重短路，導(dǎo)致火災(zāi)。那些3D真空爐是專門為粘結(jié)劑噴射工藝設(shè)計(jì)的，該設(shè)備額外配有保護(hù)系統(tǒng)，有助于使?fàn)t子長(zhǎng)期處于良好狀態(tài)。當(dāng)然，與常規(guī)的真空爐一樣，除了粘結(jié)劑噴射，該爐型還可用于任何其他工藝。歸根結(jié)底，真空爐是增材制造行業(yè)的推薦解決方案；但是并不是每臺(tái)真空爐都能滿足增材制造的特殊工藝要求。</p><p style="text-indent:25px">真空爐在密閉爐體內(nèi)形成負(fù)壓真空環(huán)境，并將熱介質(zhì)水注入爐體。熱介質(zhì)水通過燃燒或其他方式加熱，然后從熱介質(zhì)水蒸發(fā)并凝結(jié)到換熱器，然后需要加熱的水由換熱器加熱。真空爐利用水在低壓下的低沸點(diǎn)的特點(diǎn)，對(duì)填充在密封爐體中的熱介質(zhì)水進(jìn)行快速加熱，使熱介質(zhì)水沸騰蒸發(fā)產(chǎn)生高溫水蒸氣，水蒸汽凝結(jié)在換熱管上，使換熱管中的冷水加熱，從而達(dá)到供應(yīng)熱水的目的。為了實(shí)現(xiàn)真空爐過程的自動(dòng)控制，自動(dòng)控制系統(tǒng)需要檢測(cè)真空度、溫度參數(shù)、工藝操作參數(shù)以及除氣室、加熱室和冷卻室的工況，保證各爐膛技術(shù)溫控要求的控制輸出。啟動(dòng)真空蝶閥應(yīng)緩慢，否則會(huì)因抽氣過急而冒油，帶來不良后果。</p><div
