FREEZE PROFILE AND HEAT BALANCE CALCULATION OF THE 160kA DRAINED CELL J.LI1,H.Q.Zhao1,Y.Q.Lai1,Y.X.Liu1,X.P.Li1 (1.School of Metallurgical Science and Engineering,Central South University,Changsha... according to the freeze profile computed and its heat balance was calculated.Compared with that of a 160kA conventional Hall-Heroult cell(H-H cell),though the melts volume of the drained cell reduced greatly......
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......
