Description for Sillimanite Refractory BricksSillimanite bricks are high-grade aluminosilicate refractory materials made primarily from sillimanite, andalusite, and kyanite through high-temperature calcination and molding. These minerals transform into mullite and silica glass phases at high temperatures. Because mullite is a highly refractory crystal, sillimanite bricks possess excellent high-temperature performance, high strength, and high stability. Sillimanite Refractory Bricks Advantages
1. High Refractoriness: Refractoriness typically exceeds 1790°C, enabling them to withstand extremely high operating temperatures.
2. Excellent High-Temperature Structural Strength: Due to the interwoven network of mullite crystals within the brick, its high-temperature flexural strength and refraction under load typically exceed 1650°C.
3. Excellent Thermal Shock Resistance: The mullite crystal structure has a low thermal expansion coefficient and isotropic properties, making it less susceptible to cracking and spalling during rapid temperature fluctuations.
4. High Volume Stability: Even with long-term use at high temperatures, the bricks exhibit minimal volume shrinkage, maintain structural stability, and are less likely to deform the kiln lining.
5. Good chemical resistance: Offers a certain degree of resistance to acidic slag and atmosphere.
6. Precise Dimensions: High-pressure molding ensures precise brick dimensions, facilitating easy laying and ensuring the integrity and airtightness of the kiln lining.Dimensions of Refractory Brick
The standard size of it is 230*114*65mm; and 230*114*76mm, 230*114*32mm, etc are also common used. Except for the common sizes, some special shapes could be customized according to the customers' requirements
Advantages of Sillimanite Bricks 1. Longer Service Life: Due to its excellent high-temperature strength, dimensional stability, and thermal shock resistance, its service life in demanding industrial kilns is typically 1-3 times longer than that of ordinary high-alumina bricks, reducing kiln downtime and maintenance and improving production efficiency. 2. Excellent Structural Stability: Its high refractoriness under load means that the bricks are less likely to soften and deform under the combined effects of high temperature and load, maintaining the structural integrity of the kiln for long periods of time and providing greater safety. 3. Energy Saving Potential: Its excellent dimensional stability keeps the kiln lining joints tight, reducing heat leakage and contributing to energy savings. 4. High Reliability: Its balanced and stable performance provides reliable protection for high-temperature industrial processes.
Product Application
Applications For Refractory Sillimanite Brick : Sillimanite brick mainly used for the molding of liquid hole in glass pool kiln, blast furnace lining, furnace throat and ceramic industrial kiln furniture. The refractory materials based on natural sillimanite also have these advantages. Therefore, sillimanite refractories are widely used in metallurgy, chemical and building materials industries
