High Purity Mullite Insulating Fire Brick For Glass Industries

Description:

Laurel supply several grades of mullite insulating brick for use in applications frm 1260℃ 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 and other ceramic materials.The carefully graded organics which are used during the manufacturing process burn out during firing to give a uniform pore structure.

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

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
