How to control the thermal expansion coefficient of alumina fire brick?

2024-01-05 Nosso blog

Alumina fire brick is the most representative product of aluminum-silicon refractory bricks. They have higher refractoriness than clay bricks and can be used for many years at high temperatures of 1300℃-1550℃ without erosion or wear. No entanto, the biggest disadvantage is that Thermal shock stability against temperature changes is relatively poor.
