Investigation on Thermo-physical Properties of Graphitized Carbon Materials
A transient experimental system was designed to determine the thermo-physical properties of the graphitized carbon material for aluminum reduction industry by employing modern electrical facilities and data acquisition apparatus. The periodic heat flow was recognized by the two thermocouples as a sinus temperature variation with decreasing amplitude and increasing phase lag when the heat wave propagated through the specimen. The thermal diffusivity can be calculated directly by processing experimental data, and then the thermal conductivity can be obtained with relation to thermal diffusivity if the specific heat and the density are known. The measuring system and the instrument are applicable in the temperature 20～300℃. The method will pave a way to obtain the available thermo -physical properties data.
