In high - temperature industries worldwide, companies often face severe challenges such as high - temperature erosion and equipment wear. These problems not only reduce production efficiency but also increase maintenance costs. Magnesium bricks have emerged as a remarkable solution to these issues.

Core Characteristics of Magnesium Bricks

High - Temperature Sintering Performance

Magnesium bricks exhibit excellent high - temperature sintering performance. They can withstand temperatures up to 1800°C without significant deformation. The reason lies in their unique chemical composition. Magnesium oxide (MgO), the main component of magnesium bricks, has a high melting point of about 2800°C. During high - temperature sintering, the particles of magnesium oxide gradually bond together, forming a dense and stable structure. This structure gives magnesium bricks high strength and good resistance to high - temperature erosion. In practical applications, it can effectively protect the internal structure of high - temperature equipment from being damaged by high - temperature flames and molten materials.

Thermal Shock Resistance

Another important characteristic of magnesium bricks is their good thermal shock resistance. In high - temperature industries, equipment often experiences rapid temperature changes. Magnesium bricks can withstand these sudden temperature fluctuations without cracking or spalling. This is because magnesium bricks have a low coefficient of thermal expansion. When the temperature changes, the volume change of magnesium bricks is relatively small, reducing the internal stress caused by temperature differences. For example, in some steelmaking processes where the temperature may change from 1500°C to room temperature in a short time, magnesium bricks can still maintain their integrity and performance.

Spalling Resistance

Magnesium bricks also have outstanding spalling resistance. In high - temperature environments, materials on the surface of bricks may peel off due to chemical reactions, mechanical stress, or thermal stress. However, magnesium bricks can resist this spalling phenomenon. Their dense structure and chemical stability prevent the penetration of corrosive substances, ensuring the long - term stability of the bricks. This property is crucial for the long - term operation of high - temperature equipment, as it reduces the frequency of brick replacement and maintenance.

Application Cases in High - Temperature Industries

One of the typical application scenarios is the regenerator of glass kilns. Before using magnesium bricks, the regenerator lining had a service life of about 1 - 2 years. The lining was severely corroded by high - temperature flue gas and molten glass, resulting in frequent shutdowns for maintenance. After replacing with magnesium bricks, the service life of the regenerator lining was extended to 5 - 7 years. This not only significantly reduced the maintenance cost but also improved the production efficiency of the glass kiln.

Customer Testimonials

Many customers have given positive feedback on the use of magnesium bricks. A manager from a steelmaking company said, "Since we started using magnesium bricks in our high - temperature furnaces, the maintenance frequency has been greatly reduced, and the production efficiency has increased by about 20%. We are very satisfied with the performance of magnesium bricks."

Conclusion and CTA

In conclusion, magnesium bricks have excellent high - temperature sintering performance, thermal shock resistance, and spalling resistance. These properties make them an ideal choice for high - temperature industries. They can effectively reduce equipment maintenance costs, improve production efficiency, and ensure the long - term stable operation of high - temperature equipment.
