White Fused Alumina (WFA) is another essential abrasive material commonly used in various refractory applications due to its unique properties. It is made from high-quality aluminum oxide powder and is characterized by its high purity, high hardness, and excellent thermal properties. Here are some key uses of White Fused Alumina in the refractory industry.
Our Product Standards
The use of White Fused Alumina in refractory applications is driven by its high purity, high melting point, and excellent thermal shock resistance. It enables the production of refractory materials and products that can withstand extreme temperatures, harsh chemical environments, and mechanical stress in various industrial processes.
High-Grade Refractory Bricks and Shapes :
WFA is a critical component in the manufacturing of high-grade refractory bricks and shapes used in high-temperature applications like steelmaking, cement manufacturing, glass production, and other industrial processes. The high purity and hardness of WFA contribute to the refractories' excellent resistance to thermal shock and corrosion.
Monolithic Refractories :
WFA is a critical component in the manufacturing of high-grade refractory bricks and shapes used in high-temperature applications like steelmaking, cement manufacturing, glass production, and other industrial processes. The high purity and hardness of WFA contribute to the refractories' excellent resistance to thermal shock and corrosion.
Refractory Mortars and Coatings :
WFA can be used in refractory mortars and coatings to improve bonding and provide better resistance to thermal cycling and chemical attacks.
Slide Gate Refractories :
In the steel industry, WFA is used in the production of slide gate plates and nozzles for controlling the flow of molten steel during casting processes. The high purity and thermal stability of WFA are critical for these refractory components' performance and longevity.
Kiln Furniture :
WFA is utilized in the production of kiln furniture, which includes supports, setters, and saggers used in the firing of ceramics, glass, and other materials. Its high temperature stability and resistance to deformation make it an ideal material for such applications.
Investment Casting :
WFA is used in investment casting applications, where it is mixed with refractory binders to create ceramic shells for precision casting of intricate metal parts.
