style="text-indent:25px">真空氣氛爐實(shí)現(xiàn)還原工藝的爐子叫還原爐，實(shí)現(xiàn)熱解法工藝的爐子叫精煉爐，兩種爐子的結(jié)構(gòu)不同，還原爐用于熔煉硅鐵以及高碳的錳鐵、硅錳、硅鈣合金等。這種爐子的結(jié)構(gòu)以及附屬設(shè)備，這是一種龐大的電熱設(shè)備。還原爐連續(xù)生產(chǎn)，定期放出渣和合金。爐子熔池一般用于大塊碳磚砌筑，爐膛為圓筒或圓錐形，爐子按有無爐蓋，可分為封閉型和敞口型。敞口型爐爐口上方有排煙罩，封閉型的爐蓋由耐火混凝土和水冷金屬結(jié)構(gòu)等制成。爐口封閉后勞動(dòng)條件好，生產(chǎn)率高，能回收爐氣，但不易操作和維護(hù)。按爐底結(jié)構(gòu)，爐子又可以分為旋轉(zhuǎn)型和固定型。</p><p

style="text-indent:25px">真空氣氛爐即真空技術(shù)與熱處理兩個(gè)專業(yè)相結(jié)合的綜合技術(shù)，是指熱處理工藝的全部和部分在真空狀態(tài)下進(jìn)行的。真空氣氛爐的移相調(diào)壓，是通過改變導(dǎo)通角的大小來調(diào)整輸出電壓，這種觸發(fā)方式連續(xù)性好，輸出電壓平穩(wěn)，無電壓沖擊，能夠限制瞬時(shí)電流，適合各種類型的負(fù)載，目前變壓器，電感線圈以及變阻性負(fù)載均采用這種觸發(fā)方式。但是這種觸發(fā)方式會(huì)對(duì)電網(wǎng)產(chǎn)生諧波干擾。真空氣氛爐的真空有利于排除吸附氣體、孔隙中的殘留氣體以及反應(yīng)氣體產(chǎn)物，對(duì)促進(jìn)燒結(jié)后期的收縮有明顯作用。如真空燒結(jié)的硬質(zhì)合金的孔隙度要明顯低于在氫氣中燒結(jié)的硬質(zhì)合金。真空氣氛爐是物體在通入一定氣體的爐膛內(nèi)進(jìn)行真空燒結(jié)的方法。上海高溫真空氣氛爐</p><p style="text-indent:25px">真空氣氛爐采用了全纖維高溫爐襯。上海高溫真空氣氛爐</p><p style="text-indent:25px">真空氣氛爐的結(jié)構(gòu)：真空氣氛爐一般由由爐體、加熱室、真空系統(tǒng)、充放氣系統(tǒng)、風(fēng)冷循環(huán)系統(tǒng)、電控系統(tǒng)、氣動(dòng)系統(tǒng)，水冷系統(tǒng)及料車組成。冷卻系統(tǒng)是對(duì)爐體、爐蓋、密封圈、真空泵及水冷電極進(jìn)行冷卻的，是真空氣氛爐的重要部分，冷卻水路應(yīng)保持暢透，否則水溫升高造成停機(jī)。用生物分解化學(xué)輔助方法處理冷卻水，目的是保持礦物質(zhì)呈懸浮態(tài)，減少橡皮管、蛇形管和水套內(nèi)沉淀物累積，以使水流暢通。這一般采用一種自動(dòng)裝置來完成，它可以監(jiān)測(cè)水的導(dǎo)電性，自動(dòng)補(bǔ)充化學(xué)劑，沖冼水路，添加新鮮水。與附屬蒸氣過濾系統(tǒng)配合，這種方法還可以保證水的pH值控制，防止在冷卻水系統(tǒng)中多余礦物質(zhì)沉積。在系統(tǒng)工作穩(wěn)定后，至少應(yīng)每月一次進(jìn)行水質(zhì)試驗(yàn)以防過處理或欠過理。對(duì)擴(kuò)散泵的蛇形管冷卻器必須特別注意，應(yīng)該經(jīng)常檢查。如果堵塞了，擴(kuò)散泵將會(huì)過熱并喪失功能，而且還進(jìn)一步引起擴(kuò)散泵加熱器燒毀，造成昂貴的、費(fèi)時(shí)的修理。當(dāng)蛇形冷卻水管堵塞時(shí)，將水路同水源斷開，排水并用壓縮空氣吹通或用稀醋酸溶液沖洗。上海高溫真空氣氛爐</p></p><br
