The reporter learned from the Henan Nonferrous Metals Industry Association that in 2010, the comprehensive AC power consumption per ton of aluminum in the electrolytic aluminum industry in Henan will drop to below 13,900 kWh/ton. If compared with the 2000 level, it means that the whole industry will save electricity this year. Up to 6.4 billion degrees. Continuous technological advancement has provided important support for energy saving, emission reduction and sustainable development of electrolytic aluminum, a high energy-consuming industry.
Electrolytic aluminum is not only one of the basic industries of the national economy, but also a typical energy-consuming household. For every ton of electrolytic aluminum produced, the current national average level consumes more than 14,000. According to relevant data, China is already the world's largest producer of electrolytic aluminum. At the end of 2009, its production capacity was about 20 million tons, accounting for 42% of the world. Henan Province is also the largest province of electrolytic aluminum in China, and its production capacity has exceeded 4 million tons. As one of the pillar industries in the province, energy conservation and consumption reduction in this industry is of great significance to energy conservation and consumption reduction in the industrial sector of the province.
According to the Henan Nonferrous Metals Industry Association, the average electricity consumption of aluminum electrolysis aluminum in Henan in the end of the "Ninth Five-Year Plan" in 2000 was 1.55 million kWh. In 2005, the end of the "Tenth Five-Year Plan" was 14.45 million kWh. A total of 1.07 million kWh is expected to drop to 139,000 kWh this year, with individual companies reaching below 135,500 kWh. In the past 10 years, the electricity consumption per ton of aluminum has dropped by 1,600 degrees, a drop of more than 10%.
"In the past few years, if the electricity consumption per cubic ton of electrolytic aluminum is reduced by more than 1000 degrees, I am afraid no one believes. Now, the facts are already in sight, mainly relying on the continuous technological innovation of the industry and the promotion and application of new technologies. Liu Libin, vice president of the Henan Nonferrous Metals Industry Association, said that since 2000, the innovation achievements of the electrolytic aluminum industry have emerged.
In 2001, Jiaozuo Wanfang successfully implemented 280KA prebaked anode aluminum electrolysis technology; in 2006, it has long been plagued by the worldwide problem of electrolytic aluminum production - aluminum electrolysis without power failure and slotting technology was overcome by Zhongfu Industry; June 2006 Wanji Aluminum has developed a fully graphitized cathode with an energy saving of 600 degrees per ton of aluminum. Subsequently, a series of new technologies were continuously introduced, including the new cathode structure high-efficiency energy-saving aluminum electrolytic cell technology pioneered in China, and the tons of aluminum will save 1000 degrees. In 2010, a new technology jointly completed by Longxiang Aluminum and Central South University realized energy saving of 1100-1200 degrees per ton of aluminum.
The birth and application of this series of technological innovations have played an important role in promoting technological progress and energy conservation in the whole industry. In the past 10 years, the overall level of China's aluminum industry has also caught up with the international leading level, the equipment level has increased rapidly, and the energy consumption level has been greatly reduced.
In 2007, the country's first aluminum electrolysis technology innovation strategic alliance was established in Henan. It was participated by 15 electrolytic aluminum enterprises in Henan and 15 well-known institutions and research institutes in China, and became one of the 17 key alliances identified by the Ministry of Science and Technology. . The reporter learned that this industry-university-research alliance has been under a series of major technical breakthroughs for more than two years, and some technologies have been used in production. Technological innovation has brought about a huge demonstration effect, and has also driven a group of enterprises to increase their investment in technological innovation.
Some experts said that compared with the international advanced level, there is still a certain gap in the energy consumption level of China's electrolytic aluminum enterprises. Further reducing energy consumption levels and reducing pollutant emissions are the top priorities that every enterprise must consider. At present, many domestic enterprises still have great potential in energy conservation and consumption reduction. The same equipment in different enterprises, the power consumption difference is up to several hundred degrees; the power consumption level among different enterprises in the industry is up to nearly a thousand degrees. Especially in the current electrolytic aluminum industry, which is in distress, strengthening technological innovation capability and accelerating technological progress will be one of the key factors for enterprises to break through the difficulties and form new competitive advantages in the future.
