Zhongfu Aluminum Corporation: Strictly Controlling Process Control to Create a Fine Electrolytic Cell

Whether the electrolyzer can run efficiently over a long period of time, in addition to the quality of the pre-building furnace, the most important thing is to maintain the stability of the technical conditions through the later period of management and maintenance.

After the long-term operation of the 400kA electrolyzers of Zhongfu Aluminum Company, the aging tanks gradually increased. How to maintain the stable operation of the electrolyzers is the top priority of the management of the electrolysis plant. The electrolysis second factory takes the hearth as the focus, fully optimizes the technical conditions, strictly controls the quality, introduces the competition mechanism, invigorates the technology management, refines the trough management, and fully promotes the fine management of the electrolyzer to a new level.

According to the monthly furnace test data, the electrolysis second plant performs the A, B, and C classification of the electrolytic cell: the thickness of the furnace floor of the A-type cell is greater than 6 cm, and the furnace bottom condition is good; the thickness of the B-type electrolytic cell furnace is 5 to 6 cm , The furnace bottom condition is general; C type electrolyzer kiln is less than 4 centimeters, the bottom condition is poor. The electrolysis second factory takes B and C tanks as the focus of attention, and strives to achieve 100% of A tanks through technical adjustments and manual assistance. It also implements 9 responsible tank managements for the head of the division, and the performance and furnace performance of the head of the division can be implemented. Quality management hooks. We strengthened the management of full-time operation process, tested two levels, salvaged carbon residue, leveled the furnace surface, etc. Each operation was strictly controlled against the standards and the pressure drop of the clamps was reduced by 10 mv on average from last year. At the same time, the electrolysis second branch invested in a new type of steady flow electrolysis cell, which has become increasingly prominent.

Through the implementation of the above-mentioned series of effective measures, by the end of August, the integrated AC power consumption of the electrolysis second factory was the best in history.
