Product Description of High Refractoriness Sillimanite Refractory Brick For Glass Kiln
Sillimanite bricks are a great choice for glass kilns because of their high heat resistance, excellent thermal shock stability, and good chemical resistance. They are made from a naturally occurring mineral called sillimanite, which is a form of aluminum silicate. Sillimanite bricks are typically used in the upper structure, cover plate, and charging area of glass kilns.
Features of Rongsheng High Refractoriness Sillimanite Refractory Brick For Glass Kiln

Benefits of Using SillimaniteBricks in Glass Kilns:
1.High heat resistance: Sillimanite bricks can withstand temperatures up to 1830°C (3326°F), which is well above the temperatures required for most glass melting applications.
2.Excellent thermal shock stability: Sillimanite bricks are resistant to cracking and spalling caused by rapid temperature changes. This is important in glass kilns, where the temperature can fluctuate significantly during the firing process.
Good chemical resistance: Sillimanite bricks are resistant to attack by most glasses and other molten materials. This helps to extend the life of the kiln lining.
3.Low thermal expansion: Sillimanite bricks have a low thermal expansion coefficient, which means that they will not expand significantly as the temperature increases. This helps to prevent the formation of cracks in the kiln lining.
If you are looking for a durable and reliable material for your glass kiln, sillimanite bricks are a great option. They can help to improve the efficiency and lifespan of your kiln.
Application of Rongsheng High Refractoriness Sillimanite Refractory Brick For Glass Kiln
Glass Industry:
Glass Melting Furnace Linings: Sillimanite bricks are champions for lining glass melting furnaces, particularly the crown, sidewalls, and forehearths. Their ability to handle high temperatures and resist chemical attack from molten glass makes them ideal.
Feeders, Forehearths, and Conduits: These critical components that channel molten glass benefit from sillimanite's resistance to heat, corrosion, and thermal shock, ensuring smooth glass flow.
Metal Industries:
Blast Furnace Linings: Sillimanite bricks can be found lining large-scale blast furnaces in the iron and steel industry. Their wear resistance, heat tolerance, and corrosion resistance contribute to a longer furnace lifespan.
Non-Ferrous Metal Applications: Sillimanite's ability to handle direct contact with liquid metal makes it suitable for use in furnaces for processing non-ferrous metals.
Other Applications:
Ceramic Kiln Furniture: Sillimanite bricks are used as kiln furniture within ceramic kilns, providing support for ceramic pieces during high-temperature firing.
Cement Industry: Sillimanite bricks find use in cement kilns, particularly in areas exposed to high temperatures and fluctuating temperatures.
Thermal Waste Recycling: Due to their thermal shock resistance, sillimanite bricks can be used in high-temperature areas of waste incineration systems.
Overall, sillimanite bricks are employed in any industrial setting that demands exceptional resistance to heat, corrosion, and thermal shock. Their versatility makes them valuable in various high-temperature processes.
