Hot blast stoves are critical components in blast furnace operations, providing the high-temperature air necessary for efficient ironmaking. To withstand extreme thermal cycling, mechanical stress, and chemical corrosion, alumina refractory bricks are widely used due to their excellent thermal stability, high strength, and superior resistance to abrasion. Kerui Refractory, a leading manufacturer of advanced refractory materials, offers a tailored alumina brick solution that ensures durability, energy efficiency, and cost-effectiveness for hot blast stove applications.
Why Choose Alumina Refractory Bricks?
Alumina bricks, with high Al₂O₃ content (typically 48%-90%), deliver outstanding performance in high-temperature environments. Key advantages include:
-
High refractoriness (up to 1800°C) for long-term stability.
-
Excellent thermal shock resistance, reducing cracking and spalling.
-
Superior corrosion resistance against alkali and iron oxide attacks.
-
Low creep rate, ensuring structural integrity under prolonged heat exposure.
