Abstract

The invention discloses an electrolytic tank capable of greatly reducing a horizontal current. The electrolytic tank comprises an anode carbon block (1), a cathode steel bar (2), a hearth (3), a cathode carbon block (4) and the like. The electrolytic tank is characterized in that the cathode steel bar (2) adopts a gradual-changing cathode pasting structure which is an incline-plane or stepped-section cathode pasting structure, and a high-temperature insulation material is filled at the inclined plane or the stepped section; the cathode steel bar (2) is proportionally arranged in the cathode carbon block (4); the width S of the large processing surface (5) of the hearth (3) is controlled at 240-269nm; and the cathode carbon block (4) is aligned at the anode carbon block (1), that is, the width of the cathode carbon block (4) is equal to the width of the anode carbon block (1) and is 600-800mm.

Description

technical field [0001] The invention relates to an electrolytic cell. Background technique [0002] Today's aluminum electrolysis industry is developing toward larger cell capacity. Since 2005, large-scale electrolyzers of 350-500kA have been built successively in China, and the existing cell types are also constantly strengthening the current. Under the tendency of electrolytic cell enlargement and current intensification, the study of electrolytic cell stability has become one of the more and more important topics in the design and production of electrolytic cell. [0003] The horizontal current in the molten aluminum is a taboo in the production of aluminum electrolytic cells, because the horizontal current in the molten aluminum interacts with the vertical magnetic field to generate electromagnetic force, resulting in the flow and fluctuation of the molten aluminum and the instability of the electrolytic cell. If the horizontal current is too large, it will have a grea...
