多溫區(qū)管式爐的保養(yǎng)：一、爐子使用或長時間不用后，要在120℃左右烘烤1小時，在300℃左右烘烤2小時后使用，以免造成爐膛開裂。爐溫盡量不要超過額定溫度，以免損壞加熱元件及爐襯。禁止向爐膛內(nèi)直接灌注各種液體及溶解金屬，保持爐內(nèi)的清潔。二、爐膛若采用剛玉爐管，依據(jù)剛玉材料的物理性質，各溫區(qū)的升﹑降溫速率不宜過快（≤5℃），嚴禁在爐管100℃以上取送物料。有利于爐管的熱應力的均勻釋放，以延長爐管的使用壽命。爐膛若采用石英管，當溫度高于1000℃時，石英管的高溫部分會出現(xiàn)不透明現(xiàn)象，這叫失透（又叫析晶性）是石英管的一個固有缺陷，屬正?，F(xiàn)象。三、管式爐在氣氛條件下使用，氣體在高溫下會膨脹，導致管內(nèi)壓力變大，使用者應及時開啟針閥，排出氣體。北京立式爐批發(fā)價真空管式爐在使用離心機之前，將其放置在穩(wěn)固，堅固的地面上。</p><div

箱式爐的安全操作：1、清理爐內(nèi)鐵屑，清掃爐底板，以免鐵屑落于電阻絲上造成短路損壞。2、入箱式爐的工件應不超過爐底板.大載荷量，裝卸工件時應確保電源斷開的情況下進行。3、汪意檢查熱電偶安裝位置。熱電偶插入爐內(nèi)后，應保證不與工件相碰。4、根據(jù)工件的圖紙要求，試驗箱式爐，確定合理的工藝范圍。按時升溫，保證出爐操作，經(jīng)常檢查儀表溫度并進行校準，防止誤操作。5、為保證爐溫，不能隨便打開箱式爐爐門，檢查爐內(nèi)情況應從爐門孔中觀察。6、冷卻劑應放置于就近方便的位置，減少工件出爐后降溫。7、出爐時應工位正確，夾持穩(wěn)固，防止熾熱工件傷害人體。8、箱式爐檢修后，必須按規(guī)定進行烘烤，并檢查爐堂及頂部保溫粉是否填滿，接地是否與爐殼緊固。 </p><p> 多溫區(qū)管式爐注意事項：1.多溫區(qū)管式爐操作注意事項爐子初次使用或長時間不用后，要在120度左右烘爐1小時，在300度左右烘烤2小時后使用，以免造成爐膛開裂。爐溫不得超過額定溫度，以免損壞加熱元件及爐襯。2.禁止向爐膛內(nèi)直接灌注各種液體及溶解金屬，保護顱內(nèi)清潔。3.爐體若采用硅鉬棒做加熱元件，依據(jù)硅鉬棒的物理特性，常溫下脆性很大，因此在加熱元件安裝好后不能隨意拆裝和搬動爐體，4.冷爐使用時，由于爐膛是冷的，須大量吸熱，所以低溫段升溫速率不宜過快，各種溫度段的升溫速率差別不宜太大，設置升溫速率時應充分考慮所燒結材料的物理化學性質，以免出現(xiàn)噴料現(xiàn)象，污染爐膛，5.定期檢查溫度控制系統(tǒng)的電器連接部分的接觸是良好，應特別注意加熱元件的各連接是否緊固。6.硅鉬棒作為加熱元件時不宜在400-700度溫度段長時間運行，否則硅鉬棒將發(fā)生低溫氧化。7.硅鉬棒做加熱元件時，長時間運行，阻值會逐漸增大，這種現(xiàn)象叫“老化”。箱式氣氛爐節(jié)能型的陶瓷纖維材料和雙層外殼結構，具有升降溫速度快，能耗低。</p><div
