Alumina Ceramic Foam Insulation Description

Alumina ceramic foam insulation has excellent resistance to corrosion and corrosion of molten aluminum, so it can effectively remove inclusions. Due to its lightweight and low thermal conductivity, the foamed alumina has less accumulated heat energy and obvious energy-saving effect. The precise appearance dimensions of alumina filter bricks can speed up the masonry speed and ensure high strength and stability of the masonry.

 

Alumina Ceramic Foam Insulation Advantages

- Higher-strength than refractory ceramic fiber and a lightweight ceramic brick.
- Low density
- Low thermal conductivity and linear thermal expansion coefficient.
- Great thermal shock resistance.
- Safe and rapid maintenance.

Alumina Ceramic Foam Insulation Application

Alumina ceramic foam insulation can be used as the heat-insulating layer of the refractory lining on the hot side, especially the high-temperature reducing atmosphere furnace (1850 °C). It can be used for a long time under 1800 °C air and reducing atmosphere.
