Product Description of High Quality Assured Dense Zircon Bricks Furnace Refractory Bricks For Enhanced Performance in Glass Kilns
Dense zircon bricks are a type of refractory brick, meaning they are used in high-temperature environments. They are made from zirconium silicate (ZrSiO4) and are known for their high density, low porosity, and excellent thermal shock resistance.
Because of these properties, they are commonly used in glass furnaces, particularly for the bottom blocks, superstructure blocks, tuckstones, transition bricks, flow blocks, and thermocouple and peephole blocks They can also be found in soda-lime glass kilns, channel blocks, and the sidewall of glass fiber kilns and floating glass tanks.
Key Properties of High Quality Assured Dense Zircon Bricks:
1.High refractoriness: They can withstand temperatures exceeding 2400°C (4352°F).
2.Excellent thermal shock resistance: They can withstand rapid changes in temperature without cracking or spalling.
3.High corrosion resistance: They are resistant to attack by molten glass and other corrosive chemicals.
4.High mechanical strength: They are strong and durable, even at high temperatures.
5.Low thermal conductivity: They help to insulate furnaces and kilns, reducing heat loss.
