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.
