The invention discloses an aluminum electrolysis special-shaped cathode electrolytic bath grooved anode structure and a roasting method thereof. The structure is characterized in that: a grooved anode (1) is provided with a groove (6), cathode lug bosses (2) of a special-shaped cathode (5) are embedded into the groove (6) of the grooved anode (1), the cathode lug bosses (2) are provided with graphite powder (3), and the cathode surface between the cathode lug bosses (2) is provided with coke granules (4). The roasting method comprises the following steps of: 1, measuring the grooved depth of the grooved anode (1); 2, paving the coke granules (4) on the cathode surface between the cathode lug bosses (2), paving the graphite powder (3) of the cathode lug bosses, hanging an anode once the coke granules and the graphite powder at an anode position are paved, and then paving the coke granules and the graphite powder of the next anode; repeating the first and second steps, and completely hanging the anodes in turn;
