Embodiment Construction

[0009] Referring to the accompanying drawings, the present invention includes a flat steel body 1, on two opposite wide surfaces of the flat steel body, there are respectively long grooves 2 that are uniformly and closely arranged on the surface of the flat steel body along the length direction of the flat steel body , the cross-section of each groove is an isosceles triangle with a waist length of 8-15 mm and a base angle of 90°-120°, so that the two opposite wide surfaces of the flat steel body form a wave groove structure.

[0010] Take the 300KA aluminum electrolytic cell as an example below to further illustrate the present invention:

[0011] The specifications of the existing cathode flat steel used in the electrolytic cell are: 2.1 m*0.2008 m*0.067 m smooth flat steel, three sides embedded in the cathode carbon block, the embedded length is 1.58m, and a single flat steel embedded The contact area of ​​the cathode carbon block is: 0.2008 m*1.58m*2+0.067 m*1.58m=0.7405㎡....

Abstract

The invention relates to a cathodic flat bar for electrolytic aluminum, comprising a flat bar body. The cathodic flat bar is characterized in that two opposing wide faces of the flat bar body are provided with full-length grooves, respectively, evenly and tightly arranged in the surface of the flat bar body along its length, the cross section of each groove is in the shape of an isosceles triangle having length of lateral sides being 8 to 15 mm and base angles being 90 to 120 DEG, and the two opposing wide faces of the flat bar body are in wavy groove structures. The cathodic flat bar has the advantages that surface area of the flat bar is enlarged, a contact line from the cathodic flat bar to a cathodic carbon block is prolonged, contact area of the cathodic flat bar and the cathodic carbon block is enlarged, and adhesion between the cathodic flat bar and the cathodic carbon block is also improved; at the premise of not changing conductivity, length, system power supply voltage and load condition, the power consumption is lowered, availability of electric energy is improved, and energy effect is evident.

Description

technical field [0001] The invention relates to a cathode flat steel for electrolytic aluminum, which belongs to the technical field of aluminum electrolytic cell cathodes. Background technique [0002] The aluminum electrolysis process is a process of purifying aluminum through the action of low-voltage and high-current direct current and alumina powder. Whether the current circuit provided by the electrolytic aluminum equipment is reasonable or not is directly related to the production cost per ton of aluminum. At present, the equipment used in China is an aluminum electrolytic cell, which includes a cell body, anode equipment, and cathode equipment. The anode equipment is mainly composed of anode guide rods, anode steel claws, and anode carbon blocks; the cathode equipment is mainly composed of cathode carbon blocks and cathode flat steel, wherein: the cathode flat steel is a strip-shaped cuboid with a smooth surface. Four cathode flat steels are placed in the cathode ca...
