Corundum Mullite High Strength for Insulating sintered mullite brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation

 

also known as Corundum Mullite High Strength for Insulating sintered mullite brick . The alumina content of more than 48% , mainly composed of corundum mullite and glass phase or light refractory materials.Volume density of 0.4 ~ 1.35g/cm3 . The porosity is 73% ~ 66% ,the compressive strength is 1 ~ 8MPa .Better thermal shock resistance .
Usually mixing high alumina bauxite plus a small amount of clay ,after grinding with gas or foam to form mud casting ,forming 1300 ~ 1500℃ firing. Sometimes can also be used to replace part of industrial alumina bauxite .

 

Production process:


Corundum Mullite High Strength for Insulating sintered mullite brick includes five parts: preparation of foaming agent, preparation of foam slurry, molding, drying and firing.


(1) Preparation of foaming agent.


(2) Modulation of foam mud.


(3) Forming.


(4) Dry.


(5) Firing.

 

 

Features:


1. High porosity


2. Small bulk density


3. Low thermal conductivity


4. Small heat capacity


5. Good thermal insulation


6. Lightweight

 

Compared with dense refractory bricks, Corundum Mullite High Strength for Insulating sintered mullite brick have the following advantages:


(1) With low heat storage and high thermal efficiency, it can speed up the turnover of intermittent operation kilns, improve production efficiency, reduce fuel consumption and save energy.


(2) Low thermal conductivity, which can reduce the thickness of the furnace wall and roof, reduce the quality of the furnace body, and simplify the structure of the furnace.


(3) The furnace temperature can become uniform. Conducive to improving product quality.


(4) The temperature outside the furnace is low, which is convenient for operation, improves labor efficiency, and improves labor conditions for kiln installation and discharge.

 

 

Application:


1. Quenching furnace


2. Annealing furnace


3. Box type electric furnace


4. Small heat treatment furnace such as pit electric furnace


5. Tunnel Kiln


6. Roller Kiln


7. Hot air stove of blast furnace


8. Coke oven and other large kilns.


Corundum Mullite High Strength for Insulating sintered mullite brick are widely used in thermal equipment in metallurgy, petrochemical, machinery, electric power, building materials, aerospace, shipbuilding and other industrial sectors.
