Description
Technical field: copper steel composite structure cathode steel bar of the present invention is the metallic conduction parts of aluminium electrolysis cell cathode carbon block rod iron group.
Technical background: existing general cathode steel bar is arranged on the metallic conduction parts in the steel bar trough of aluminium electrolysis cell cathode carbon block bottom; Arrange along the cathode block length direction; The cathode steel bar material is a soft steel, and section form along its length is the homalographic rectangle, and its purpose of design is that the overcurrent of the negative electrode aluminium liquid of aluminium cell is conducted to the negative electrode big bus that confluxes; When accomplishing the transition of carbon-metal conduction, be used for reducing and suppressing the generation of aluminum liquid horizontal electric current in the aluminium electrolysis cell.
But because the cathode steel bar that is arranged in the steel bar trough of aluminium electrolysis cell cathode carbon block bottom is in the high-temperature zone; Cathode steel bar with the metallic steel material prepn; Under electrolysis worst hot case state, its resistivity of material can increase significantly, and resistance value also can sharply increase; Cause cathode steel bar resistance value along its length to be far longer than the horizontal resistance value of aluminium electrolysis cell cathode carbon block top aluminium liquid; Promptly by electrolyzer middle part to the electrolyzer sidepiece along cathode steel bar aluminium liquid layer resistance value along its length, the therefore basic horizontal current of having eliminated not the aluminium liquid layer in the aluminium cell causes the variation of current trend, magnetic field and aluminum liquid magnetic rotational flow; Cause the rising of aluminium cell volts lost, current efficiency descends.
Summary of the invention: in order to overcome the shortcoming of prior art, eliminate the horizontal current in the aluminium cell, reduce the magnetic rotation stream fluctuation of aluminium liquid; Improve current efficiency; The present invention proposes a kind of novel aluminum cell cathode steel bar structural design scheme, its technical thought is to lean on the inner textural copper coin of aluminium cell at the cathode steel bar length direction, utilizes the conductivity of copper material to be superior to the characteristics of aluminium liquid conductivity; Improve the inner specific conductivity of cathode steel bar; So as to eliminating the generation of the aluminum liquid horizontal electric current in the aluminium cell, reduce idle power consumption, thereby improve the electrolytic efficiency of electrolyzer.
According to the aluminum electrolyzing cell used copper steel composite structure of technique scheme cathode steel bar; Adopt two kinds of metallic substance compound structures of copper steel; The i.e. inboard current enter setting of leaning on the electrolyzer middle part at cathode steel bar is configured with conductive copper plate, with the conductivity method that improves the inboard current enter of cathode steel bar, eliminates the horizontal current of aluminium liquid layer or suppresses the aluminum liquid horizontal current's intensity; Reach the density that increases aluminium liquid vertically passing electric current, improve the purpose of current efficiency
According to technique scheme, the inboard current enter welding structure of cathode steel bar has conductive copper plate.
