Customer Case: Fused Magnesia Bricks Boost Stable High-Temperature Production for Enterprises

In the high-temperature industrial landscape, fused magnesia bricks have emerged as a crucial component, providing reliable support for stable production processes. This article delves into the unique properties, application scenarios, and advantages of fused magnesia bricks through real customer cases, highlighting why they are a reliable and efficient choice for enterprises in high-temperature production.

Unique Properties of Fused Magnesia Bricks

Fused magnesia bricks are primarily made from fused magnesium, which endows them with a range of outstanding properties. Firstly, they exhibit excellent resistance to alkaline slag. In high-temperature environments where alkaline slag is prevalent, such as in some steelmaking processes, the corrosion rate of ordinary refractory materials can reach up to 2-3 mm per month, while fused magnesia bricks can reduce this rate to less than 0.5 mm per month, significantly extending the service life of the lining.

Secondly, these bricks possess a high refractoriness. With a melting point typically above 2800°C, they can withstand extremely high temperatures without significant deformation or softening. This high refractoriness ensures their stability and reliability in high-temperature furnaces and kilns.

Moreover, fused magnesia bricks have good thermal stability. They can endure rapid temperature changes without cracking or spalling. For example, in a glass melting furnace where the temperature fluctuates frequently during the melting and refining processes, fused magnesia bricks can maintain their integrity, reducing the risk of furnace damage and production interruptions.

Application Scenarios in High-Temperature Industries

Fused magnesia bricks find wide applications in various high-temperature industries. In the steel industry, they are used in the linings of electric arc furnaces, converters, and ladles. The high refractoriness and resistance to alkaline slag of fused magnesia bricks can effectively protect the furnace lining from the erosion of molten steel and slag, improving the quality of steel products and reducing production costs.

In the cement industry, these bricks are employed in the rotary kilns. The thermal stability of fused magnesia bricks allows them to adapt to the high temperatures and long - term operation of the kilns, ensuring the continuous and stable production of cement.

In the glass industry, they are used in the melting tanks. The resistance to chemical corrosion of fused magnesia bricks prevents the contamination of the glass melt, thereby improving the quality of glass products.

Advantages Compared with Other Refractory Materials

Refractory Material	Refractoriness	Resistance to Alkaline Slag	Thermal Stability
Fused Magnesia Bricks	Above 2800°C	Excellent	Good
Clay Bricks	About 1600 - 1750°C	Poor	Fair
Silica Bricks	About 1690 - 1730°C	Poor	Fair

As shown in the table, fused magnesia bricks outperform other common refractory materials in terms of refractoriness, resistance to alkaline slag, and thermal stability. This makes them a more suitable choice for high - temperature and harsh - environment applications.

Real Customer Case

A steelmaking enterprise was facing frequent lining replacements in its electric arc furnace due to the severe corrosion of the previous refractory materials. After switching to fused magnesia bricks, the service life of the furnace lining increased from 300 heats to over 800 heats. This not only reduced the maintenance frequency and cost but also improved the production efficiency. The enterprise reported a 15% increase in annual steel production and a significant reduction in production downtime, which had a positive impact on its overall profitability.
