JM 30 Low Iron Mullite Insulation 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.
JM 30 Low Iron Mullite Insulation Brick is also called high alumina insulating brick. It contains more than 48% Ai2O3 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.

 

 

 

Features:

1.  JM 30 Low Iron Mullite Insulation Brick has advantages with small bulk density, high cold crushing strength, and high refractoriness under load, small dimension tolerance and good thermal shock resistance.
2. JM 30 Low Iron Mullite Insulation Brick has the lowest and most stable thermal conductivity in various insulating refractory bricks.
3. JM 30 Low Iron Mullite Insulation Brick can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained.

 

 

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.


JM 30 Low Iron Mullite Insulation Brick are widely used in thermal equipment in metallurgy, petrochemical, machinery, electric power, building materials, aerospace, shipbuilding and other industrial sectors.
