Furnace electrode graphite cavity

The utility model relates to the technical field of electrode graphite, and discloses an electrode graphite cavity in a furnace, which comprises a furnace body and a graphite electrode, the side wall of the furnace body is provided with a graphite cavity for embedding the graphite electrode, one end of the graphite electrode far away from the graphite cavity is provided with two air inlets for inputting protective gas into the graphite cavity to prevent oxidation, and the outer sides of the air inlets are fixedly provided with connecting pieces. A fixing piece is fixed to the side wall of the bottom of the furnace body and arranged at the bottom of the graphite electrode, and a heat preservation cavity is further formed in the furnace body and makes contact with the graphite cavity. The utility model has the following advantages and effects: through the arrangement of the air inlet and the air outlet, protective gas can be injected into the graphite cavity, graphite is prevented from being contacted with air
