Optimizing control method for furnace wall thickness of aluminum electrolysis cell

The invention aims to provide an optimizing control method for a furnace wall thickness of an aluminum electrolysis cell, and aims to solve the problem that an optimizing control method is absent for the furnace wall thickness. The optimizing control method comprises the following steps of: calculating a furnace wall thermal resistance coefficient, calculating the furnace wall thickness at each group of anodes, determining furnace wall thickness measuring frequency and performing stable optimizing control on the furnace wall thickness. According to the optimizing control method provided by the invention, a measuring period is determined according to a practical condition of the furnace wall thickness, the measuring period and frequency can be prolonged when the furnace wall thickness is good, the practical monitoring needs of a furnace wall are met, working efficiency is further improved, labor intensity is reduced, and labor power is saved; stable optimizing control is performed on the furnace wall thickness by regulating an electrolyte temperature, an initial crystallization temperature and a furnace wall side cell shell temperature, so that the requirements, on the furnace wall thickness, in production are met, a phenomenon that the furnace wall of the electrolysis cell is thin or the electrolysis cell does not have the furnace wall is prevented, the problem that technological economic indexes are affected and even furnace leakage risk happens due to the fact that cell condition fluctuation is generated in operation of the electrolysis cell is avoided, and stable, efficient and long-period operation of the electrolysis cell is guaranteed.
