[0002] A graphite electrode refers to a high-temperature-resistant graphite conductive material made of petroleum coke and pitch coke as aggregates, coal tar pitch as a binder, through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization, and machining, and is called an artificial graphite electrode.

[0003] As an indispensable conductive material in high-temperature industrial fields such as steel smelting and non-ferrous metal smelting, when the graphite electrode is placed in a fixed roasting furnace for heating, there are limitations, resulting in uneven heating of the electrode blank. The unevenness will affect the performance and service life of the electrode. Therefore, we need to design a roasting device for the production and processing of graphite electrodes, which adopts a clamping and rotating structure and a pushing structure, and different parts face the heat source in turn, avoiding local overheating or overcooling. Thus, the structure of the graphite electrode becomes more uniform. During the roasting process, volatile substances in the pitch are generated. Rotation can make the volatile components more evenly discharged from the electrode, avoiding local accumulation, reducing the generation of pores and cracks, and improving the electrode density and strength.

During the roasting process, volatile substances in the pitch are generated. Rotation can make the volatile components more evenly discharged from the electrode, avoiding local accumulation, reducing the generation of pores and cracks, and improving the electrode density and strength, so as to solve the above-mentioned background technical problems.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A roasting device for the production and processing of graphite electrodes includes a moving structure installed in the inner cavity of the roasting device.

The connecting column 10 is rotatably connected with the large gear 12. The central axis of the top of the disc 8 is fixedly connected with a mounting column 11, and the mounting column 11 is rotatably connected with the large gear 12. Through the arrangement of the mounting column 11, when the large gear 12 rotates at the top of the disc 8, the mounting column 11 plays a role of limiting the large gear 12, thereby avoiding the phenomenon that the large gear 12 is separated from the small gear 14 during the rotation process, and improving the stability of the large gear 12 during the rotation process.
