Abstract

This invention discloses one aluminum electrolyte liquid fluctuation method and its probe, which comprises the following steps: a, setting two test points in electrolyte in same position for two points difference; according to this, computing test point for electrolyte lowering; measuring electrolyte tank pressure to test electrical balance to get aluminum tank ustatic to compute real time electrode distance by unit height electrolyte lowering and tank voltage and ustatic.

Description

technical field [0001] The invention relates to a test method and a test probe for the fluctuation of aluminum liquid in an aluminum electrolytic cell. Background technique [0002] The research on the fluctuation of molten aluminum at home and abroad mainly focuses on the research and numerical simulation of the fluctuation mechanism of molten aluminum. The numerical simulation of molten aluminum fluctuation is a hot spot in the past and present research. In order to facilitate the simulation calculation, some necessary assumptions are usually put forward, such as shallow water Approximate model has obtained more accurate calculation results. However, the physical and chemical processes in the aluminum electrolytic cell are very complicated, and the effects that can be obtained through numerical simulation are quite limited. However, due to the experience and limitations of model parameter values ​​in numerical simulation, it is often necessary to combine and verify the me...
