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.
- 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.
