Thermal Shock Resistance Al2O3 Mullite Brick Fireproof For HBS

 

Thermal Shock Resistance Al2O3 Mullite Brick Fireproof For HBS also known as mullite lightweight insulating firebrick of high purity refractory powder, according to product requirements proportion, adding organic composite filler, the vacuum extrusion molding, high temperature sintering refractory insulation mullite insulating brick .In the main phase of mullite alumina, alumina content in general 65% ~ 75%.A high degree of fire resistance, up to 1790 degrees celsius. Load softening temperature 1600 ~ 1700 degrees to start. Room temperature compressive strength of 70 ~ 260MPa. Good thermal shock resistance. The sintered mullite and fused mullite brick two .

 

a) According the made method, Thermal Shock Resistance Al2O3 Mullite Brick Fireproof For HBS can be divided into burnt brick, unburned brick, and electric smelting brick.
b) According the shape and size,
Thermal Shock Resistance Al2O3 Mullite Brick Fireproof For HBS can be divided into standard brick, general brick and abnormal shape brick.
c) According the content of the Al2O3,
Thermal Shock Resistance Al2O3 Mullite Brick Fireproof For HBS can be divided into fire clay brick and high alumina brick.
