Mullite Lightweight Fire Bricks

  

1. Mullite lightweight brick is made from natural raw materials, low iron high alumina, mullite crystal structure to phase-based high-quality insulating firebrick.

2. Selected high purity refractory powders, according to the proportion of products required to join the organic compound filler, vacuum compression molding, high temperature sintered mullite lightweight products.

3. Energy efficiency, high strength, good thermal shock resistance, low thermal conductivity, resistance to penetration ability, resistance to erosion is an ideal long-life product.

4. The product can be widely used in metallurgy, petrochemical, machinery, ceramics and other industries, for industrial furnace lining or insulation. 

 

Features:

1. Low impurities.

2. Low thermal conductivity.

3. Good heat shock stability.

4. High hot compressive strength.

5. Accurate size, the bricks can be processed into special shapes.

 

Applications: Lightweight millite bricks are widely used as industrial furnace hot face lining and back lining in metallurgy, petrochemical, building materials, ceramics, machinery and other industries. Such as: cracking furnace, conversion furnace, heating equipment, refining equipment, recycling equipment, stove, heating furnace, soaking furnace, heat treatment furnace, resistance furnace, tunnel kiln, roller kiln, shuttle kiln, bell kilns, glass kiln and so on.
