On Heat Transfer within Gas Quenching Furnace
2005 (English)In: IASME Transactions, 2005Conference paper (Refereed)
Gas quenching in an industrial furnace is considered. The flow and thermal fields in the furnace withtwo different charges, plates and cylinders, in axial flow are studied numerically. Details of the thermal fieldcharacteristics are presented. A variation in heat transfer of maximum 125 % is observed in the whole basket, themaximum heat transfer being obtained on the first bodies of the charge. The heat transfer is found to be uniformlydistributed in the middle of the charge, with mean values 50 % higher than on the sides. Recommendations forimprovement of current vacuum quenching furnaces are proposed.
