Problems solved by technology

Since the shoulder is in the shape of an inclined surface with corners, the distance of the current to the corner of the shoulder is the longest, which not only affects the uniform distribution of the anode current, but also increases the voltage drop of the anode. The amount of material used in the manufacture of the anode is large, and the scrap electrode replaced during use The amount is large; the stress generated by the anode during molding, roasting, assembly and casting is not easy to be evenly distributed, and sometimes there will be cracks at the mouth of the bowl, which will affect the qualified product rate of the anode assembly

Embodiment 1

[0032] Such as Figure 2-5 As shown, in this embodiment, the prebaked anode for aluminum electrolysis includes a lower body 6 and a boss 1, and a plurality of carbon bowls 2 are arranged inside the boss 1 for installing conductive devices. Wherein, the shape of the boss 1 is set so that the distance between the inner wall of the carbon bowl and the outer edge of the boss is consistent or tends to be consistent at the horizontal position.

[0033] Specifically, in this embodiment, the boss 1 includes a plurality of successively connected frustums, and the number of the frustums is the same as that of the carbon bowls 2, and each carbon bowl is respectively arranged inside each frustum.

[0034] Preferably, in this embodiment, in each frustum of the boss, the outer edges of two adjacent frustums are connected as a whole through an arc-shaped transition, and the arc used for the transition between the frustums faces the convex surface. The inner direction of the table cuts the c...

Embodiment 2

[0049] The prebaked anode in this embodiment includes a lower body and a boss, wherein the structure of the boss is the same as that of the boss in Embodiment 1, and the structure of the lower body is the same as that of the traditional prebaked anode. That is to say, in this embodiment, only the boss structure of the traditional prebaked anode is improved, but the structure of the lower body is not improved.

Abstract

The invention provides a low-consumption prebaked anode for aluminium electrolysis. The low-consumption prebaked anode for aluminium electrolysis comprises a lower part body and a boss; the boss is provided with a carbon bowl, and the shape of the boss is arranged to enable the horizontal-position distance between all parts of the inner wall of the carbon bowl and all parts of the outer rim of the boss to be consistent to tend to consistent. The prebaked anode helps to effectively reduce carbon consumption, also reduce electric consumption and also improve the current efficiency.

Description

technical field [0001] The invention relates to a low-consumption prebaked anode for aluminum electrolysis. Background technique [0002] The prebaked anode for aluminum electrolysis is the second major raw material that must be used in aluminum electrolysis production. In the process of aluminum electrolysis production, it is responsible for conducting electricity, participating in electrochemical and chemical reactions, and bearing. For high-energy-consuming enterprises such as aluminum electrolysis plants, they pay special attention to the efficient use of resources, and always try to reduce consumption through various technical measures to reduce production costs. Therefore, it is also hoped that the structure of prebaked anodes can be Develop in the direction of energy saving, consumption reduction and efficient utilization of resources. [0003] For prebaked anodes, according to the relationship between carbon consumption, power consumption and current efficiency of a...
