Product Description

 

Alumina bubble brick is made from alumina bubbles and alumina powders, together with other adhesives, burnt by 1750ºC. It belongs to the super high temperature thermal insulation material which is widely used as the industrial furnace lining under 1800 ºC . Since its high porosity, it cannot be applied to the part that contact slag, or it will be damaged by the slag permeation. Also if used as the furnace lining, the temperature rising rate cannot be too sharp, or it will crack and reduce its service life.

APPLICATION

Metallurgy induction furnace lining
Petrochemical industrial gas furnace
Thermal insulation lining
Reaction Furnace lining

FEATURES

 

Thermal stability
Low thermal conductivity
High porosity
High refractoriness under load
Low thermal linear change
