馬弗爐,是爐子,熔爐的意思。馬弗爐在中國的通用叫法有以下幾種:電爐、電阻爐、茂福爐、馬福爐。馬弗爐是一種通用的加熱設(shè)備,依據(jù)外觀形狀可分為箱式爐、管式爐、坩堝爐。
馬弗爐應(yīng)用范圍:
(1)熱加工、工業(yè)工件處理、水泥、建材行業(yè),進行小型工件的熱加工或處理。
(2)醫(yī)藥行業(yè):用于藥品的檢驗、醫(yī)學(xué)樣品的預(yù)處理等。
(3)分析化學(xué)行業(yè):作為水質(zhì)分析、環(huán)境分析等領(lǐng)域的樣品處理。也可以用來進行石油及其分析。
(4)煤質(zhì)分析:用于測定水分、灰分、揮發(fā)分、灰熔點分析、灰成分分析、元素分析。也可以作為通用灰化爐使用。
馬弗爐使用注意事項:
當(dāng)馬弗爐次使用或長期停用后再次使用時,必須進行烘爐干燥:在20~200℃打開爐門烘2-3h,200~600℃關(guān)門烘2-3h。
實驗前,溫控器應(yīng)避免震動,放置位置與電爐不宜太近,防止過熱使電子元件不能正常工作。搬動溫控器時應(yīng)將電源開關(guān)置“關(guān)”。
使用前,將溫控器調(diào)至所需工作溫度,打開啟動編碼使馬弗爐通電,此時電流表有讀數(shù)產(chǎn)生,溫控表實測溫度值逐漸上升,表示馬弗爐、溫控器均在正常工作。
(一)工作環(huán)境要求無易燃易爆物品和腐蝕性氣體,禁止向爐膛內(nèi)直接灌注各種液體及熔解金屬,經(jīng)常保持爐膛內(nèi)的清潔。
(二)使用時爐膛溫度不得超過爐溫,也不得在額定溫度下長時間工作。實驗過程中,使用人不得離開,隨時注意溫度的變化,如發(fā)現(xiàn)異常情況,應(yīng)立即斷電,并由專業(yè)維修人員檢修。
(三)使用時爐門要輕關(guān)輕開,以防損壞機件。坩堝鉗放取樣品時要輕拿輕放,以保證安全和避免損壞爐膛。
(四)溫度超過600度后不要打開爐門。等爐膛內(nèi)溫度自然冷卻后再打開爐門。
(五)實驗完畢后,樣品退出加熱并關(guān)掉電源,在爐膛內(nèi)放取樣品時,應(yīng)先微開爐門,待樣品稍冷卻后再小心夾取樣品,防止?fàn)C傷。
(六)加熱后的坩堝宜轉(zhuǎn)移到干燥器中冷卻,放置緩沖耐火材料上,防止吸潮炸,裂,后稱量。
(七)搬運馬弗爐時,注意避免嚴(yán)重共振,放置遠(yuǎn)離易燃易爆、水等物品。嚴(yán)禁抬爐門,避免爐門損壞。
