Abstract

Provided are an aluminum electrolytic graphite crucible experimental device and experimental method. The device comprises a computer and a heating furnace; a bottom furnace door of the heating furnace is installed at the top end of a lifting mechanism; two silicon carbide rod sets are arranged in the heating furnace, when the device is used, a graphite crucible is located in the heating furnace, an anode conductive rod and a cathode conductive rod are installed, the cathode conductive rod is connected with the graphite crucible, and a graphite anode is installed on the anode conductive rod and located in the graphite crucible. An aluminum ingot is put into the graphite crucible, heating is conducted, after the aluminum ingot and an electrolyte are completely melted, the furnace temperature is kept constant, the heights of melting aluminum and the electrolyte are measured, and data of electric currents changing along with changes of the distance between the anode conductive rod and the bottom face of the graphite crucible are recorded; changes of the electric currents and voltages are observed when an anode effect occurs. The experimental device can simulate an electrochemical reaction in an industrial field device, a good teaching effect is achieved through an early theoretical calculation and arrangement and late experimental phenomenon observation, and meanwhile experimental data can provide guidance and reference data for a production field.
