EQUIPPING OF AN ALUMINUM ELECTROLYZING BATH WITH THE BUS-BARS Russian patent published in 2005 - IPC

FIELD: chemical industry; equipping of an aluminum electrolyzing bath with bus-bars.

SUBSTANCE: the invention is pertaining to equipping of an aluminum electrolyzing bath with bus-bars. Equipping of an aluminum electrolyzing bath with the upper two-sided feeding of an electrical current to the anode at a two-row longitudinal location of the electrolyzers in the body contains: cathodic and anodic buses coupled by three rising mains with cathodic buses of a preceding electrolyzing bath; two cross-sectional buses connecting the cathodic buses of the right side of a preceding along the current run electrolyzing bath with an inlet terminal of the left-hand anode bus; and the cathodic buses of the left side of the preceding electrolyzing bath - with an outlet terminal of the right-side anode bus. At that the made with three rising mains bus-bar has the following distribution of the current among the rising mains, %: the right-side inlet rising main - 39-42, the left-side inlet rising main - 33-35, the left-side outlet rising main - 25-27. At that 9-11 % of the current loading is fed to the left-side inlet rising main from the right side of a cathode bus-bar of the preceding electrolytic bath through a transversal bus connecting the cathode buses of the right side of a preceding current run direction electrolytic bath with an inlet terminal of the left-side anode bus and located on the an inlet butt of the cathode below a marker pip of the bottom; 15-17 % of current-loading of the left-side outlet rising main is fed to the left-side anode bus;, 10-12 % is fed to the right anode bus through the transversal bus connecting the cathodic buses of the left-side of the preceding electrolytic bath with an outlet terminal of the right anodic bus and located above the level of a melt in an electrolytic bath. At that the current-loading is fed to the left-side outlet rising main by separate packs of buses from the left-side of the cathodic bus-bar of the preceding electrolytic bath, and anodic buses on an inlet and an outlet are supplied with jumpers. The invention ensures minimization of the vertical component of the magnet field, its symmetrical distribution, alternating vibrations, an even distribution of the current-loading on an anodic block.

EFFECT: the invention ensures minimization of the vertical component of the magnetic field, its symmetrical distribution, alternating vibrations, an even distribution of the current-loading on an anodic block.
