Importance and application of brucite powder in metallurgical industry

As an important pillar industry of the national economy, the development level of the metallurgical industry directly affects the country's economic construction and industrial competitiveness. In the metallurgical process, the use of various auxiliary materials is crucial. Among them, brucite powder, as a multifunctional mineral material, plays an irreplaceable role in the metallurgical industry with its unique physical and chemical properties.

Application of brucite powder in the metallurgical industry

Provide high-purity magnesium oxide

Preparation of magnesium oxide: brucite powder can be directly calcined to produce high-purity magnesium oxide. Magnesium oxide is an important refractory material in the metallurgical industry. It has excellent high temperature resistance and chemical stability. It is widely used in lining materials of metallurgical furnaces such as blast furnaces, converters, and electric furnaces. It can effectively protect smelting equipment, extend its service life, and improve production efficiency.

Preparation of magnesium chloride: brucite powder can also be used to prepare magnesium chloride, which is the main raw material for electrolytic production of magnesium metal. Magnesium metal can be used in the metallurgical industry to make alloys, deoxidizers, etc. It has important industrial value and can improve the performance of metal materials such as steel, and enhance the quality and added value of products.

Improve the smelting process

Removing impurities and treating slag: Brucite powder is mixed with dolomite and calcined. The product can be used in the steel manufacturing industry to remove impurities such as P and S and treat slag. This helps to improve the purity and quality of steel products, reduce pollution during the smelting process, reduce subsequent refining costs, and improve the economic benefits of the enterprise.

Improve the life of the furnace lining: Brucite powder is mixed with dolomite and calcined to produce a periclase aggregate with high thermal conductivity and electrical insulation. As a refractory brick product, this material has a service life 2 to 3 times longer than smelting magnesite, which can significantly increase the life of the lining of the metallurgical furnace, reduce the replacement frequency and maintenance cost, reduce the risk of production interruption, and ensure the continuity and stability of production.

Environmental protection and energy saving

Flue gas desulfurization: Brucite powder can be used as a flue gas desulfurizer and added to boiler fuel to reduce the harm of high mercury and high sulfur fuel to the boiler and reduce the emission of sulfur dioxide and other harmful gases. This not only helps to reduce the pollution of the metallurgical industry to the environment, but also improves the environmental image of the enterprise, meets the requirements of the country's increasingly stringent environmental protection policies, and reduces the environmental risks and potential fines of the enterprise.

Energy saving and consumption reduction: Since brucite can release water vapor when heated, its decomposition absorbs less heat, which can play a certain energy-saving role in the smelting process and reduce energy consumption. This helps to reduce the production cost of metallurgical enterprises, improve energy utilization efficiency, and enhance the market competitiveness of enterprises.

Economic benefits

Cost reduction: The preparation process of brucite powder is relatively simple and the cost is low. Compared with traditional refractory materials and desulfurizers, the use of brucite powder can significantly reduce the production cost of the metallurgical industry, increase the profit margin of enterprises, and enhance the economic benefits of enterprises.

Rich resources: my country has rich brucite resources, such as Kuandian, Liaoning, Heimulin, Shaanxi, Ji'an, Jilin, etc. There are large brucite deposits. This provides a stable supply of raw materials for the metallurgical industry, reduces dependence on external resources, reduces the risks brought by raw material price fluctuations, and ensures the production stability and sustainable development of enterprises.

Conclusion

Brucite powder has important application value in the metallurgical industry, which can effectively improve production efficiency, improve product quality, reduce production costs, and bring significant environmental benefits. With the continuous development of the metallurgical industry and the increasing requirements for environmental protection, the application prospects of brucite powder will be broader.
