Alumina hollow sphere castable

The biggest characteristic of alumina hollow sphere castables is high softening temperature, high strength and good heat insulation performance. Alumina hollow sphere castable service temperature is generally between 1600 °C and 1700 °C. Alumina hollow sphere castable is an ideal thermal insulation material for carbon black reaction furnace and high temperature special inner liner. Alumina hollow sphere castable has been widely used in high-temperature and ultra-high temperature furnaces such as petrochemical industrial gasifiers, carbon black industrial reactors, metallurgical industrial induction furnaces, etc., and has achieved very satisfactory energy-saving effects.
