Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of graphite electrode processing, in particular to an asphalt removing device for the surface of a graphite electrode. Background Art
[0002] The asphalt removal device on the surface of graphite electrodes in current life is a device used to remove asphalt residues on the surface of electrodes during the production process of graphite electrodes. Graphite electrodes are indispensable materials in industrial processes such as electric arc furnace steelmaking and electroslag remelting. During the production process, asphalt needs to be added to graphite powder as a binder to form electrode blanks. After the electrode blanks are sintered, the asphalt will carbonize and form residues. These residues need to be removed to ensure the quality and performance of the electrodes.
[0003] Existing asphalt removal devices used for graphite electrode surfaces usually use blades to remove asphalt, but the asphalt fragments vary in size, and the blades close to the graphite electrode are damaged. Asphalt residues that cannot be removed will affect the conductivity and high-temperature resistance of the electrode, thereby reducing the overall quality of the electrode. Residual asphalt may cause the electrode to malfunction during use, increase the frequency of maintenance and replacement of electrodes, and thus increase maintenance costs. If the asphalt removal device cannot adapt to electrodes of different sizes, additional manual intervention or equipment replacement may be required, which will reduce production efficiency.
