From January 6 to 8, the 2024 Annual Summary Conference for the Steel Extreme Energy Efficiency Project was held in Zhanjiang, Guangdong Province. The conference released the 2024 version of the Extreme Energy Efficiency Technology List (T80) and the 200th report of the Environmental Product Declaration (EPD) platform for the entire steel industry chain. Industry experts were invited for specialized discussions. Notable attendees included Gan Yong, an academician of the Chinese Academy of Engineering, and Jiang Wei, Deputy Secretary of the China Iron and Steel Industry Association, who engaged in in-depth discussions on energy conservation and carbon reduction in the steel industry.

The Steel Extreme Energy Efficiency Project, as part of the national strategy, aims to promote energy-saving and carbon-reduction transformations across the entire industry. Since the project's inception, the steel industry has achieved significant reductions in energy consumption and carbon emissions through systematic energy-saving modifications. This summary conference further emphasized the need for the industry to focus on optimizing all process nodes to comprehensively enhance energy efficiency and achieve a low-carbon transition.

PART 01: The Key Role of Permanent Magnet Motors in the Steel Production Process

Under the "dual carbon" goals outlined in the 14th Five-Year Plan, the steel industry faces immense pressure for energy conservation and carbon reduction due to its high energy consumption. Permanent magnet motors, known for their efficiency, low loss, and long lifespan, have become a crucial technological support for energy conservation and carbon reduction throughout the steel production process.

Permanent magnet motors play a vital role in various key stages of steel production, covering the entire process from raw material handling to finished product transportation, including sintering, ironmaking, steelmaking, rolling, and waste recycling:

• Sintering and Pelletizing Processes: Permanent magnet motors demonstrate excellent energy efficiency in the sintering machine fan systems, significantly reducing energy consumption during the sintering process while optimizing emission control.

• Blast Furnace Blowing and Circulation Systems: In the ironmaking stage, energy consumption from large equipment like blast furnace blowers is substantial. Permanent magnet motors, with their efficient design, greatly reduce energy usage and enhance system operational efficiency.

• Converter Steelmaking: Permanent magnet motors provide more efficient power support for electrical equipment, achieving energy savings and carbon reduction in oxygen blowing systems and flue gas treatment systems in converter steelmaking.

• Rolling Process: In the rolling process, permanent magnet motors improve overall equipment energy efficiency and reduce electrical energy waste through efficient power transmission and precise control in cooling cycles.

• Waste Recycling and Transportation: The application of permanent magnet motors and permanent magnet electric rollers in waste transportation and recycling equipment not only enhances resource recovery efficiency but also effectively reduces system losses, supporting the green circular development of the steel industry.

Jiang Wei's Speech

In his speech, Secretary Jiang Wei emphasized that the Extreme Energy Efficiency Project, as one of the three major initiatives in the steel industry, is essential for serving national strategies and aligns with the demand for low-carbon transformation in the new era. Since its launch, the project has sparked a comprehensive energy-saving and carbon reduction upgrade wave across the industry, achieving significant interim results and contributing positively to cost reduction and survival for enterprises. Overall, the Steel Extreme Energy Efficiency Project is in a phase of innovative exploration and active practice, with room for further improvement and immense potential.

PART 02: Supporting the Industry's Low-Carbon Transition and Setting Industry Benchmarks

JASUNG has successfully served numerous well-known domestic and international steel enterprises, including Baowu Steel, Baotou Steel Group, Ansteel Group, and Shougang Group, with applications spanning sintering, ironmaking, and rolling processes. One steel company reported a 15% reduction in energy consumption and a 30% decrease in equipment failure rates in the sintering stage after introducing JASUNG's permanent magnet motors, achieving a win-win situation in energy savings and cost optimization.

Under the guidance of this Extreme Energy Efficiency Project, JASUNG continues to optimize product design, enhancing the adaptability and energy efficiency of permanent magnet motors in complex process environments. The company has also developed a series of comprehensive energy-saving transformation plans for the steel industry, establishing a leading benchmark for energy conservation and carbon reduction. Together, we are advancing the achievement of energy-saving and carbon reduction goals across the steel production process, helping the industry steadily progress on the path of green and low-carbon transformation.
