Corundum fire brick is the cornerstone of high-performance glass melting furnaces. For global glass manufacturers, the durability of the furnace lining directly determines the operational efficiency and long-term profitability of the plant.
As a leading manufacturer with over 20 years of export experience, Henan Ruitai Lianxin Refractory Materials Co., Ltd. understands that selecting the right refractory material is not just a purchase—it is an investment in furnace longevity.
Why corundum refractories are essential for glass melting
Glass melting is one of the most challenging industrial processes. It is characterized by extremely high temperatures—often exceeding 1600°C—and severe chemical corrosion caused by alkaline vapors.
In such contexts, electro-fused corundum and chrome-corundum refractory bricks are viable options. Both types of refractory bricks possess the requisite chemical stability and mechanical strength to withstand these rigorous operating conditions.
With an alumina （Al₂O₃）content typically exceeding 90%, these bricks provide superior resistance to slag penetration and thermal shock.
Key benefits of using corundum bricks in kiln linings
-
Extreme temperature resistance
Our dense corundum fire brick maintains its structural integrity at temperatures where standard high alumina bricks might begin to soften.
-
Superior corrosion resistance
In the melting zone of glass kilns, where the molten glass is most aggressive, zirconium corundum fire brick (AZS) acts as an impenetrable barrier, preventing refractory particles from contaminating the glass quality.
-
Reduced maintenance downtime
By extending the service life of critical kiln areas, such as the throat and doghouse, corundum refractories significantly reduce the frequency of costly cold repairs.
