Description:
It is a kind of the light weight refractory products which contains the alumina content range from 30% to 46% .
Ingredients and water mixed together made the plastic pug or slurry, then Extruded-Form or molding by casting, dry, and firing in the 1250-1350°Oxidizing atmosphere.
Applications:
Mainly used as thermal insulating layer without the liquid melt touched or gas pickling in the constructing the various industry furnaces.
The working temperature is 1200-1400°C
