China Aluminum Aluminum Reduction Technology Saves 2.5 Billion Yuan in Cost Per Year

According to the news on June 2nd, “Chinalco will promote this new technology within the entire Chinalco aluminum system within the next 1-2 years, and it will contribute 2.5 billion yuan in profits to the company after full application.” Vice President of Chinalco The “new technology” in the manager’s mouth is “a new type of structural aluminum cell technology” independently developed by Chinalco, and the application of this technology will save more than 1,300 kilowatt-hours of electricity per ton of aluminum.

As the world's most advanced aluminum electrolyzer technology, China Aluminum cracked the "new structure of aluminum electrolyzer technology" can increase the power utilization rate of aluminum electrolysis process by 5%-7%, DC power consumption is lower than 12,000 kwh, while at home and abroad The average DC power consumption level is 13000-14000 kWh.

According to Chinalco's introduction, Chinalco will complete the experiment of all types of electrolyzers in the first half of next year, and the full application of more than 5,000 electrolyzers in the entire company will not be until 2011. As the third largest manufacturer of electrolytic aluminum in the world, Chinalco has a capacity of 4 million tons of electrolytic aluminum. After calculation, the application of this technology will be 5.2 billion kilowatt-hours of electricity for Chinalco, reducing the annual equivalent emission of greenhouse gas 400. Ten thousand tons.

"Aluminium companies will lose a profit of 600 million yuan for every 1 cent increase in electricity price." Yuhong said that the cost of the new technology for the transformation of each electrolyzer is only 20,000-30,000 yuan, and after full application, It will bring economic benefits of 2.5 billion yuan per year to the company.

According to the reporter, in addition to the "new structure of aluminum electrolyzer technology," Chinalco also holds a number of non-ferrous metal smelting general technology, and these technologies are expected to get the country's support in the promotion of technological innovation. In addition, on May 2, the state allocated the first two-year discount loans with a total investment of nearly 7.5 billion yuan to 41 non-ferrous metal technological transformation projects, of which Chinalco has 3 projects.
