Product Description

High alumina insulating refractory brick

Characters of High alumina insulating refractory brick
 
High aluminum heat insulation refractory brick has a small volume density, low thermal conductivity, excellent heat insulation performance with stable quality. 
Its alumina content is more than 48%, bulk density of 0.4~1.35g/cm3 porosity is 66%~73%,compressive strength1~8MPa. with good thermal shock resistance.
 
Applications of High alumina insulating refractory brick

Can be used for all kinds of high temperature furnaces lining or insulating layer. Mainly used as thermal insulating layer without the liquid melt touched or gas pickling in the constructing the various industry furnaces.
