High-performance refractory mullite brick for industrial stoves
A high alumina refractory with mullite (3Al2O3·2SiO2) as the main crystalline phase.The general alumina content is between 65% ~ 75%.In addition to mullite, the mineral composition contains a small amount of vitreous phase and quartzite in those with low alumina content.The higher alumina content also contains a small amount of corundum.High refractoriness, up to more than 1790℃.The initial temperature of load softening is 1600 ~ 1700℃.The compressive strength at room temperature is 70 ~ 260MPa.Good thermal shock resistance.There are two kinds of sintered mullite brick and fused mullite brick.
It is mainly used for hot blast furnace top, blast furnace body and
bottom, regenerative chamber of glass melting furnace, ceramic
sintering kiln, dead Angle furnace lining of petroleum cracking
system, etc.
There are two kinds of sintered mullite brick and fused mullite
brick.Sintered mullite brick is made of high bauxite clinker as the
main raw material, adding a small amount of clay or raw bauxite as
binder, after molding and firing.Electrofused mullite bricks are
made of alumina, industrial alumina and refractory clay with
charcoal or coke fine particles as reducing agent.The
crystallization of fused mullite is larger than that of sintered
mullite, and its thermal shock resistance is better than that of
sintered mullite.

Litestone brick is an aluminium-silicon refractory product with mullite as the main crystalline phase.Because the main crystalline phase of mullite brick is mullite, the properties of mullite brick are as follows: refractoriness at about 1850℃, high softening temperature under load, low creep rate at high temperature, good thermal shock resistance, acid slag corrosion resistance, otherwise the mullite will be decompresented;Mullite also decomposes in reducing atmosphere above 1370℃.Mullite will decompose at temperatures above 1650 ° C, even if it is not resistant to low oxygen partial pressure in a reducing atmosphere.Mullite brick is mainly used for hot blast furnace, torpedo car lining, ceramic industrial kiln lining, saggar, kiln furniture and so on.
