Brief introduction of alumina bubble bricks
Aluminum bubble bricks are a kind of light refractory materials with high temperature resistance and energy conservation, which are very stable in various atmospheres. Especially suitable for 1800 ℃ high temperature kiln.
Applications of alumina bubble bricks
Alumina bubble bricks are not only widely used in high-temperature and ultra-high temperature kilns such as gasifiers in petrochemical industry, reaction furnaces in carbon black industry, induction furnaces in metallurgical industry, etc., but also show good energy-saving effects.
