Introduction of Ronghua Sillimanite Brick
Sillimanite refractory bricks are made from sillimanite, quartz, and other minerals through calcination or casting. Their alumina content is as high as 62%. They are a special type of high-alumina refractory brick. Their physical and chemical properties are superior to those of high alumina refractory bricks. Therefore, they are an important refractory material for the construction of industrial kilns and other high-temperature equipment.
Advantages of Ronghua Sillimanite Fire Brick
- High Refractoriness
Sillimanite blocks boast exceptional refractoriness. Their temperature resistance ranges from 1770 to 1830 degrees Celsius. And their load-softening temperature falls between 1600 and 1650 degrees Celsius. This makes them suitable for prolonged operation at high temperatures. - High Structural Strength
Sillimanite bricks exhibit remarkable structural strength. They have a cold Crushing Strength (CCS) of 45-60 MPa. This high mechanical strength translates to superior abrasion resistance and bending strength. - Strong Resistance to Acid and Alkali Corrosion
This brick demonstrates exceptional resistance to chemical attack from acids, alkalis, and other corrosive media, including molten glass. - Excellent Thermal Shock Resistance
With a Permanent Linear Change (PLC) of -0.1 to 0.1%, sillimanite bricks exhibit remarkable dimensional stability and structural integrity under rapid temperature fluctuations. - High Workability
Ronghua Refractory caters to its partners’ needs by offering customized cutting and processing of sillimanite bricks. This facilitates convenient installation and construction. - Energy Saving and Emission Reducing
Sillimanite refractory blocks possess low thermal conductivity. This feature effectively retains heat within high-temperature equipment to minimize heat loss and reduce energy consumption.
Applications of Ronghua Sillimanite Refractory Blocks
This brick finds extensive applications in various high-temperature industries. It primarily serves as furnace linings and in other critical components.
- Furnace linings: Glass melting furnaces, copper smelting furnaces, zinc dust furnaces, blast furnaces, hot blast stoves, lime kilns, ceramic kilns, metallurgical furnaces,
Coke ovens, oil refining furnaces, etc. - Other critical components: Electrolytic cells, wear-resistant tubes, impellers, pump chambers, cyclones, feeders, nozzles, refractory bricks, etc.
