Buy high quality low price MAGNESITE BRICKS 90% MAGNESIA Size 230 X 115 X 75 MM Density 2900 Kg/M3 made by Wedge for high-temperature applications.
Magnesite Bricks are a type of refractory brick made primarily from magnesite (magnesium carbonate, MgCO₃) that is calcined to form magnesium oxide (MgO). These bricks are highly valued in high-temperature applications due to their excellent refractory properties, resistance to chemical attack, and durability in harsh environments.
Key Features of Magnesite Bricks:
1. High Refractoriness: Magnesite bricks have high melting points and can withstand temperatures up to 2,000°C (3,632°F) or more, making them ideal for use in extremely high-temperature applications.
2. Good Corrosion Resistance: They exhibit strong resistance to chemical attack from basic slags, lime, and iron-rich environments, which makes them suitable for environments where acidic refractories would fail.
3. High Thermal Conductivity: These bricks have good thermal conductivity, which can be an advantage in specific applications where rapid heat transfer is necessary.
4. Resistance to Spalling: Magnesite bricks have good resistance to spalling (breaking apart due to rapid temperature changes) and thermal shock, which is crucial in many industrial processes.
5. Types of Magnesite Bricks:
• Ordinary Magnesite Bricks: Made from naturally occurring magnesite and used in various applications.
• Direct-Bonded Magnesite Bricks: Made with higher purity magnesite and fired at higher temperatures, resulting in strong bonds between grains for better durability.
• Fused Magnesite Bricks: Produced from fused magnesite grains, offering higher strength and better resistance to corrosion.
• Magnesia-Carbon Bricks: A combination of magnesia and carbon, often used in steel-making furnaces due to their excellent slag resistance and thermal shock resistance.
Applications:
• Steel Industry: Used extensively in steelmaking, including in electric arc furnaces, converters, and ladles, where resistance to basic slags is crucial.
• Cement Kilns: Often used in the rotary kilns for cement production.
• Non-Ferrous Metallurgy: Applied in furnaces for non-ferrous metal production, such as in the lining of copper and nickel converters.
• Glass Furnaces: Suitable for areas exposed to aggressive chemical environments.
Benefits:
• Durability and Longevity: High resistance to chemical and thermal stresses extends the life of the furnace linings.
• Improved Efficiency: Enhances the energy efficiency of high-temperature processes by maintaining structural integrity under extreme conditions.
• Cost-Effectiveness: Though the initial cost may be higher, the longevity and durability of magnesite bricks can lead to lower maintenance costs and reduced downtime.
Magnesite bricks are a critical component in many high-temperature industrial processes due to their robust properties.
