Modeling and Simulation of Heat Transfer in Loaded Continuous Heat Treatment Furnace () 摘要:Continuous furnaces are widely used in the heat treatment of mass-produced parts. However, the heating up process of parts in continuous furnace is still decided by experience. In this paper the heat transfer in the continuous furnace is formulated firstly. The heat balance in each zone is discussed......
. The potential drop of the system, freeze profile and heat balance were analyzed to evaluate their variation with technical parameters when designing the 150 kA conventional cell based drained cell... and change the thermal input and output of the cell, so it is necessary to study the heat balance issue based on designing the lining structure and selecting appropriate operational technologies. ......
