Description

technical field [0001] The invention relates to the field of aluminum electrolytic cells, in particular to a method for simulating the interface of molten aluminum by using a computer. Background technique [0002] There are two molten liquids in the aluminum electrolytic cell. Since the density of the aluminum liquid is greater than that of the electrolyte, there is an obvious layering phenomenon in the cell. The upper layer is the electrolyte, and the lower layer is the aluminum liquid. The electromagnetic force generated under the action of the electric field and magnetic field in the aluminum electrolytic cell deforms the aluminum liquid interface, thus causing a change in current, which in turn changes the electromagnetic force, and this coupling effect leads to periodic fluctuations in the aluminum liquid level. This periodic fluctuation will cause the change of the pole distance, which will cause a short circuit between the poles, resulting in the failure of the elect...

Problems solved by technology

The electromagnetic force generated under the action of the electric field and magnetic field in the aluminum electrolytic cell deforms the aluminum liquid interface, thus causing a change in current, which in turn changes the electromagnetic force, and this coupling effect leads to periodic fluctuations in the aluminum liquid level

This periodic fluctuation will cause a change in the pole distance, which will cause a short circuit between the poles, resulting in the failure of the electrolytic cell to work normally.

If it is not discovered in time and measures are taken to stabilize and fluctuate violently, it will cause the aluminum electrolytic cell to consume a large amount of electric energy, and the electrolysis efficiency will be greatly reduced. What's more, it will cause the cell to stop and affect the production of the aluminum electrolytic cell

The aluminum electrolytic cell is in a high temperature state during normal operation during the production process, and the high-temperature melt in the cell is very corrosive, and general materials will corrode quickly in the cell, making it difficult to realize on-line monitoring and control of the working status of the electrolytic cell , it is very difficult to directly measure the information of the fluctuation of molten aluminum
