Description of Alumina Bubble Castable:
Alumina bubble castables have high refractoriness under load, high strength, and good heat insulation performance. Service temperature can reach 1600℃-1700℃. It is an ideal thermal insulation material for carbon black reaction furnaces and high-temperature special lining permanent layers. It has achieved very satisfactory energy-saving effects in high-temperature and ultra-high temperature furnaces such as petrochemical industrial gasifiers, carbon black industrial reaction furnaces, metallurgical industrial induction furnaces, etc. .
