Fused cast mullite bricks, It is a high performance refractory brick mainly composed of bauxite (mullite). They are manufactured through a process of melting bauxite. Fused bauxite bricks have
many superior properties that make them perform well in high temperatures and harsh environments.
With a denser density, fused cast mullite bricks not only have high refractoriness under load, high strength at high temperature and good wear resistance, but also have the characteristics of
strong corrosion resistance, low thermal expansion coefficient and high thermal conductivity. In addition, thermal shock resistance is also better than other fused bricks.

Main characteristics of Fused cast mullite bricks :
1. High refractory properties: Fused bauxite bricks can work stably at high temperatures exceeding 1600°C, making them very suitable for high temperature environments.
2. Low thermal expansion coefficient: This brick has a low thermal expansion coefficient, which makes it less likely to deform or crack when the temperature changes, enhancing its durability.
3. Excellent thermal shock resistance: Due to its good thermal stability, fused bauxite bricks can withstand rapid temperature changes and are suitable for operating environments with greater
thermal shock.
4. Chemical stability: Fused bauxite bricks have good corrosion resistance to most chemical media, especially acidic and alkaline media.
5. Excellent mechanical strength: The structure of this brick is very strong and can withstand greater mechanical pressure and impact.
Application of Fused cast mullite bricks:
1. High-temperature furnaces: such as glass melting furnaces, steel smelting furnaces, aluminum smelting furnaces, etc.
2. Electric arc furnaces and converters: high-temperature furnace linings and bottoms in the steel manufacturing process.
3. Cement kilns: used in high-temperature environments in the cement manufacturing process.
4. Heat treatment equipment: such as annealing furnaces, heating furnaces, etc.
