Embodiment Construction

[0033] In the production equipment of electrolytic aluminum, etc., the cathode steel rod is a metal conductive part arranged in the steel rod groove at the bottom of the cathode carbon block of the aluminum electrolytic cell. It is arranged along the length direction of the cathode carbon block. The material of the cathode steel rod is low carbon steel. The cross-sectional shape in the direction is an equal-area rectangle. Its design purpose is to conduct the overcurrent of the cathode aluminum liquid of the aluminum electrolytic cell to the cathode busbar, and to reduce and suppress the aluminum electrolytic cell while completing the carbon-metal conductive transition. Generation of horizontal current in molten aluminum. However, since the cathode steel rod installed in the steel rod groove at the bottom of the cathode carbon block of the aluminum electrolytic cell is in a high temperature zone, the material resistivity of the cathode steel rod made of metal steel material wil...

Abstract

The invention provides a cathode steel bar for effectively restraining horizontal current. Copper is adopted for improving the electric conductivity of the cathode steel bar. The center of the cathodesteel bar (1) is provided with a drill hole (11) in the axial direction; a copper core (2) which has the same diameter with the drill hole (11) is placed inside the drill hole (11); the copper core (2) makes close electric contact with the cathode steel bar (1); the length of the copper core (2) is 1 / 2 to 4 / 5, preferably 3 / 4 of the length of the cathode steel bar (1); a baffle (4) is arranged atan open end of the cathode steel bar (1); and the baffle (4) is welded on the cathode steel bar and is a little sunk in the end face of the cathode steel bar. In use, the cathode steel bar is not prone to fall off, being separated or being damaged and can effectively strain the horizontal current.

Description

(1) Technical field [0001] The invention relates to a cathode steel rod, in particular to a copper core cathode steel rod for effectively suppressing horizontal current and a manufacturing method thereof. (2) Background technology [0002] In the production equipment of electrolytic aluminum, etc., the current common cathode steel rod is a metal conductive part arranged in the steel rod groove at the bottom of the cathode carbon block of the aluminum electrolytic cell, arranged along the length direction of the cathode carbon block, and the material of the cathode steel rod is low carbon steel , the cross-sectional shape along the length direction is an equal-area rectangle. Its design purpose is to conduct the overcurrent of the cathode aluminum liquid of the aluminum electrolytic cell to the cathode busbar, and to reduce and suppress the aluminum while completing the carbon-metal conductive transition. The generation of horizontal current in the aluminum liquid in the elec...
