Abstract

The present invention discloses a step type paste bundling cathode structure, wherein a step-shaped paste bundling surface (4) is arranged close to an electricity outlet end of a cathode steel bar (2), the position of the step-shaped paste bundling surface is filled with a high temperature resistance insulation material, the high temperature resistance insulation material is ceramic fiber cotton or other materials having the same effect, and the number of steps can be two or more. The step type paste bundling cathode structure has the following characteristics that: construction is simple, no material processing problem exists, the effect is significant, and the step type paste bundling cathode structure is a cathode structure for easily reducing a horizontal current, has a high practical value, and can be used in old electrolyte tank transformation or new electrolyte tank design.

Description

technical field [0001] The invention relates to a cathode structure of an electrolytic cell, belonging to the technical field of aluminum electrolysis. Background technique [0002] The interaction between the horizontal current and the vertical magnetic field is the main reason for the fluctuation of the molten aluminum in the electrolytic cell, and the fluctuation of the molten aluminum will cause a voltage swing. In addition, the horizontal current will accelerate the electrolyte flow rate, erode the side of the furnace, damage the furnace, cause damage to the tank lining, and affect the life of the tank. Therefore, the horizontal current has a great influence on the current efficiency, stability, and cell life. Analyzing the cause of the horizontal current and the countermeasures have far-reaching significance for production management. [0003] Generally, there are two reasons for the generation of horizontal current in the aluminum liquid layer: (1) The horizontal cur...
