馬弗爐簡(jiǎn)介馬弗爐（Mufflefurnace），Muffle是包裹的意思，furnace是爐子，熔爐的意思。馬弗爐在中國(guó)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(jìn)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(yàn)、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(jìn)行石油及其分析。（4）煤質(zhì)分析：用于測(cè)定水分、灰分、揮發(fā)分，北京馬弗爐廠家、灰熔點(diǎn)分析、灰成分分析、元素分析。也可以作為通用灰化爐使用。馬弗爐的使用首先要看使用的是什么型號(hào)的，北京馬弗爐廠家，簡(jiǎn)單描述大概使用方法：1.電爐不需特殊安裝，只需平放在室內(nèi)地面或臺(tái)架上。控制器應(yīng)放在工作臺(tái)上，工作臺(tái)面的傾斜度不得超過5度?？刂破麟x電爐比較小距離不得少于?？刂破鞑灰朔旁陔姞t上面，以免影響控制器正常工作。2，北京馬弗爐廠家.與控制器及電爐相連的電源線，開關(guān)及熔斷器的負(fù)載能力應(yīng)稍大于電爐的額定功率。有熱電偶插入爐膛20-50mm，孔與熱電偶之間空隙用石棉繩填塞。連接熱電偶至控制比較好用補(bǔ)償導(dǎo)線（或用絕緣鋼芯線），注意正負(fù)極，不要接反。3.接線時(shí)。工業(yè)上用的馬弗爐一般由電熱元件、砌體、金屬殼體、爐門、爐用機(jī)械和電氣控制系統(tǒng)等組成。北京馬弗爐廠家</p><div
