Another ultra-high-purity magnesium oxide production line in China realizes commercial production Hay:B01BJTS

Recently, the 1,000-ton production line of "Ultra-high-purity Magnesium Oxide Technology by Galvanic Cell Method" officially realized commercial production. This technology will not only increase the original purity of China's magnesium oxide by 1%, but will also promote China's steel industry into an ultra-clean era.

High-purity magnesium oxide has the characteristics of high thermal conductivity, insulation, light transmission, etc., and will be integrated and developed with multiple industries in the future. With the breakthrough of ultra-high purity magnesium oxide technology and officially entering the primary stage of industrialization, many industries in China will usher in substantial benefits.

In recent years, although the quality of my country's special steel has improved significantly, the output and quality still lag far behind the international advanced level. To reduce the introduction of inclusions, we must rely on the high purity of refractory raw materials.


The reporter learned that "Ultra-high-purity magnesium oxide technology by galvanic cell method" can produce ultra-high-purity magnesium oxide with the highest purity of 99.95%, filling the gap of high-purity magnesium oxide in China's metallurgical industry, and breaking the previous high-purity magnesium oxide. The situation of relying on imports. As a refractory material, high-purity magnesium oxide can be widely used in the production of functional materials for refined steel. It can not only directly promote the improvement of steel cleanliness, but also shorten the gap between China and developed countries in the field of superalloy technology. Industrial chain reengineering and value chain promotion are of great significance.

In addition, the construction of high-end cement kilns such as nuclear power cement and marine engineering cement, and high-end glass kilns such as medicinal glass and optical lens glass will also benefit from breakthroughs in ultra-high-purity magnesium oxide technology. At the same time, ultra-high purity magnesium oxide is also one of the best stabilizers for zirconia ceramic materials such as turbine engine blades, spacecraft insulation tiles, rockets and missile radar shields.


Electric furnaces using high-purity magnesium oxide as refractory materials release only 23.2% of carbon dioxide per ton of steel of blast furnaces. This means that by greatly increasing the proportion of electric arc furnace steel, energy saving and emission reduction in the steel industry can be quickly achieved. As the steel industry is the largest source of carbon emissions in the industrial sector, its carbon reduction efforts will have an important impact on the smooth realization of my country's carbon peak and carbon neutral goals.
