Product Description

JM23 JM26 JM28 Mullite Insulation Brick B5 B6 Light Weight 0.5g/cm3-1.3g/cm3 Density


Leadsun Refractory supply several grades of insulating brick for use in applications from 900℃ to 1760℃.Each grade of brick is formulated to meet specific thermal and physical requirements.After firing each brick is machined to close dimensional tolerances.


Insulating bricks are manufactured utilising exceptionally high purity clays or mullite or other ceramic materials.The carefully graded organics which are used during the manufacturing process burn out during firing to give a uniform pore structure.

Mullite Insulating Brick Application:

The mullite bricks are widely applied to industrial furnace, glass furnace, chemical industrial furnace, utility industry furnace lining, smelting furnace, and heat insulation ventilation wall.Mullite Insulation Brick is mainly used for lining of blast furnace, hot blast furnace, electric furnace roof, reverberatory furnace and rotary kiln. In addition, high alumina bricks also widely used as open hearth regenerative lattice brick, pouring system with plug, such as nozzle brick.

1. Furnaces of metallurgy industry, heat treatment furnace

2. Furnaces of chemical industry and construction industry.

3. Furnace of incineration of garbage, recirculating fluidized bed furnace


Characteristics of Mullite Insulation Bricks

1. Mullite insulation bricks have high fire resistance and can be directly exposed to flames.

2. Mullite fire bricks have the characteristics of light weight, high strength, low thermal conductivity and good thermal shock resistance.

3. Mullite bricks have the advantages of high porosity, small bulk density, good thermal insulation effect, and long service life.

4. Mullite refractory bricks are important energy-saving, thermal insulation and refractory materials for various industrial kilns.


Applications

1.Primary hot face linings

2.Back-up insulation for furnaces and kilns

3.Flue insulation

4.Sulphur recovery equipment

5.Hot blast stoves


Features

1.High insulating properties

2.Strong compressive strength

3.Low heat storage

4.High purity

5.Tight dimensional tolerance

6.Energy saving

7.Low impurities
