On September 26th, the first electrolysis workshop of Yuefeng Aluminum-Magnesium Alloy Branch was filled with thunderous applause. With the successful injection of the first batch of shining primary aluminum, the No. 318 smart electrolytic cell was officially put into operation in the 500KA series. The achievement of this key milestone not only marks the completion of the technological iteration of the company's 500KA electrolytic aluminum series, but also highlights the technological breakthrough of the enterprise in the field of smart smelting.
The smart electrolyzer put into operation this time integrates multiple cutting-edge technological innovations and builds a production system with an optimized entire process. The core structure adopts a new type of edge lining technology that combines a fully graphitized cathode, phosphorus pig iron casting and copper-embedded steel rods, and is combined with an anti-turbulence busbar design around the cell, fundamentally enhancing the operational stability of the electrolytic cell. The superstructure innovatively applies upper-level gas collection, new guide rod sealing and insulation type trough cover technology, which can preheat the alumina in advance and significantly improve the energy utilization efficiency. The anode system is equipped with composite energy-saving steel claws and aluminum-steel direct welding technology, further reducing production energy consumption. The intelligent upgrade has become the core competitiveness of this electrolytic cell. The cell is equipped with an intelligent shell-breaking and single-point feeding system, combined with dual online detection devices for temperature and current distribution, to achieve real-time monitoring of production parameters. The intelligent control of the exhaust gas from the electrolytic cell, the intelligent regulation of the furnace hall and the smart online management system operate in a coordinated manner, just like installing a "smart brain" on the electrolytic cell. It can dynamically adjust the operation parameters according to the working conditions, enabling the traditional smelting process to achieve digital and precise control.
The technical indicators have confirmed the remarkable achievements of this upgrade. The direct current power consumption per unit of molten aluminum, the pressure drop at the bottom of the furnace, and the temperature of the channel steel bars are all controlled within an extremely optimal range. Calculated based on the annual production capacity, significant energy-saving benefits and carbon reduction achievements can be achieved each year. The successful commissioning of this smart electrolytic cell is an important achievement of the branch company's "innovation-driven strong technology" strategy. The person in charge of the aluminum-magnesium alloy branch company introduced. As a key breakthrough in green aluminum smelting technology, the research and application of smart electrolytic cells have continued the advantages of the branch company in the field of energy conservation and consumption reduction. Previously, the branch company has achieved the excellent result that the AC power consumption of molten aluminum has consistently exceeded the industry target.
At present, the Aluminum-magnesium Alloy Branch Company has initiated the series promotion work of smart electrolytic cells. The stable operation of the first device has accumulated valuable experience for the subsequent comprehensive upgrade of the 500KA series. Next, the branch company will take this operation as a starting point, deepen the integration and innovation of digital technology and smelting processes, and write a new chapter of green development in the field of new non-ferrous metal materials.
