High quality manufacturer fused magnesia alumina spinel for refractory fireproof brick is also called high alumina insulating brick. It contains more than 48% Al2O3 and mainly consists of mullite and glass phase or corundum. It is usually made of high bauxite and a small amount of clay. After the raw materials are grounded, it is made into mud. Then it is cast and molded and fired at 1300~1500℃. Sometimes industrial alumimum is used to replace bauxite. Inorganic matter is added as ignition loss substance in order to increase the porosity of the refractory.

 

High quality manufacturer fused magnesia alumina spinel for refractory fireproof brick is an ideal insulating refractory refractory material, with advantages of high strength, low thermal conductivity, good insulation property and low price. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

 

In order to improve product performance, industrial alumina, corundum, sillimanite, kyanite, and silica are added The powder can be produced with bulk density above 0.4g/cm3. Al2O3 content and bulk density are different, the highest operating temperature is also different, usually 1250-1350 ℃, some up to 1550 ℃

 

Production process:


High quality manufacturer fused magnesia alumina spinel for refractory fireproof 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, High quality manufacturer fused magnesia alumina spinel for refractory fireproof 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.


High quality manufacturer fused magnesia alumina spinel for refractory fireproof brick are widely used in thermal equipment in metallurgy, petrochemical, machinery, electric power, building materials, aerospace, shipbuilding and other industrial sectors.
