Description

Technical Field

[0001] The utility model belongs to the technical field of electrode paste production, and specifically relates to an electrode paste production mixing and kneading device. Background Art

[0002] Electrode paste is a conductive material used in electric furnaces such as ferroalloy furnaces and calcium carbide furnaces. Electrode paste is also called self-baking electrode. It relies on the heat in the submerged arc furnace to complete the baking. Therefore, the key to the use of electrode paste is to match the electrode consumption rate with the baking rate. As the technology of submerged arc furnaces develops gradually towards large-scale and closed directions, the electrode has reduced the amount of conductive heat and radiant heat obtained by the open furnace in the past to only conductive heat during the baking process. Therefore, the heat obtained by the electrode from the furnace is greatly reduced, which requires improving the sintering performance of the electrode paste to make up for this deficiency.
