style="text-indent:25px">真空馬弗爐由于爐腔內(nèi)基本沒有或*有少量的熱傳遞介質(zhì)，工件和電熱元件之間傳熱方式主要是熱輻射，熱對流和熱傳導的作用很弱，可以忽略不計。電熱元件作為熱源，以熱輻射的方式把熱量傳給工件，同時也傳給爐內(nèi)各個部件。輻射的熱能一部分被工件和爐內(nèi)部件吸收，而使其溫度升高，另一部分熱量又被反射回來。這樣在爐子內(nèi)部存在熱量的輻射、吸收、反射等多個熱交換過程。充氣馬弗爐內(nèi)部充有氣體或本身處在大氣壓下，河北大型馬弗爐有限公司，如果爐內(nèi)氣體是靜態(tài)的，河北大型馬弗爐有限公司，工件和電熱元件之間三種傳熱方式并存，但熱對流和熱輻射仍起著主要作用，熱對流是自然對流換熱，河北大型馬弗爐有限公司。馬弗爐功能強大，兼容性好，能滿足多行業(yè)需求。河北大型馬弗爐有限公司</p><div
