Product Description

Unshape Fused Mullite Refractory Brick with Good Thermal Shock Resistance for Glass Furnace
The Description:
Refractory brick is the main component material of glass kiln, which has a decisive impact on glass quality, energy consumption and product cost. Glass narrow commonly used 5 kinds of firebrick:

1.AZS and high zirconia bricksAZS brick is mainly to improve the corrosion resistance and wear resistance of the production process, in addition to taking oxidation melting, so that the carbon content of the product is reduced to 0.005%, the glass phase precipitation temperature is increased to 1450ºC. The casting and annealing processes have also been improved, and high zirconia bricks with AZS.ZrO2 content above 90 with small or even no shrinkage holes have been produced.
2. Chromium bricks and chromium-containing bricks Compact chromium oxide bricks formed by isostatic pressing are used for the side walls, necks or other severely eroded parts of E glass and C glass pond kilns, with a life of 6 to 7 years.
3. Alkaline brick:High purity direct bonded alkaline brick fired at 1800ºC is mostly used for regenerator wall and arch.
4. Olivine bonded phase of olivine brick has particularly strong corrosion resistance, and the corrosion resistance of magnesium brick can be improved by increasing the content of magnesium olivine in the bonded phase of magnesium brick. To this end, 20 fine powder of magnesia olivine is added to the ingredients of magnesia brick to form a magnesia olivine binding matrix that can protect magnesia particles and reduce erosion. The price is relatively cheap, and it has been widely used in the middle of the glass kiln regenerator cell lattice body abroad.
5. Barium feldspar olivine brickIn view of olivine's good corrosion resistance and poor thermal shock resistance, the introduction of barium feldspar in its binding phase can significantly improve the heat shock resistance of bricks. Barium feldspar is formed during the firing process and is only present in the bonded matrix phase.

Product feature:
High temperature resistance: The operating temperature of the glass kiln is usually very high, so the refractory brick must be able to withstand high temperatures. This usually means that they need to have a high melting point and high resistance to high temperatures.Corrosion resistance: Acidic and alkaline substances are involved in the production of glass, so refractory bricks need to be corrosion resistant and able to resist the corrosion of glass components on the brick.Thermal expansion matching: The temperature in the glass kiln can change significantly, so the refractory brick needs to have a thermal expansion coefficient that matches that of other materials to prevent cracks and damage.Compactness: Refractory bricks should have high compactness to reduce penetration and prevent melt from penetrating into the interior of the brick, thereby extending the service life of the brick.Mechanical strength: Firebricks need to be mechanically strong enough to withstand the pressures and mechanical stresses that may exist in the kiln.Good thermal conductivity: Good thermal conductivity helps to evenly distribute heat and improve the thermal efficiency of the glass kiln.Low water absorption: Low water absorption helps reduce the risk of bricks bursting during heating and cooling.Property: Firebricks should meet the relevant health and standards to ensure the property during the operation of the glass kiln.Easy processing: Refractory bricks should be easy to cut and process to accommodate different shapes and sizes of kilns.Wear resistance: Considering that there may be wear in the kiln, especially in the movement area of the material, the refractory brick should have a certain wear resistance.
