Recently, our company has made a major breakthrough in magnesium smelting technology—the independently developed bottom-tapping magnesium reduction shaft furnace technology has been successfully put into operation and is running stably. This innovative bottom-tapping process significantly improves production efficiency and magnesium recovery rates, with the current single-pot capacity reaching 120 kg, marking a significant step forward in the company’s green and low-carbon metallurgical technology.
Traditional magnesium smelting processes typically use horizontal retorts or top-tapping methods, which suffer from high energy consumption and operational complexity. Our bottom-tapping technology optimizes the shaft furnace structure and reduction conditions, enabling efficient condensation and collection of magnesium vapor. Key advantages include:
Increased Single-Pot Capacity: A design capacity of 120 kg per pot, improving efficiency by over 20% compared to conventional methods.
Reduced Energy Consumption: The shaft furnace’s superior sealing enhances thermal efficiency, cutting comprehensive energy consumption per ton of magnesium by 15%.
Eco-Friendly Production: An intelligent control system minimizes dust and exhaust emissions, meeting green production standards.
Since its commissioning, the production line has maintained stable operation, with product purity exceeding 99.95%, fully meeting the demands of high-end magnesium alloys and aerospace materials. The project team leader stated, “The successful application of bottom-tapping technology not only overcomes the limitations of traditional processes but also lays a solid foundation for large-scale production.”
The company plans to further expand production capacity and explore applications of this technology in recycled magnesium smelting. This breakthrough not only strengthens our leadership in magnesium smelting technology but also provides a new direction for the global magnesium industry’s low-carbon development.
