Process Of Production:
Fused mullite powder
It is manufactured from pure quartz sand and industrial alumina in super-large electric arc furnace.
it has a high content of mullite crystals which confer high melting point ,excellent thermal stability ,low reversible thermal expansion and resistance to thermal shock and chemical corrosion at high temperature .
It is widely as lining bricks in glass body kiln and large hot wind furnace in iron-making blast furnace ,as well as in ceramic kiln and petrochemistry .
Fused Mullite is produced by the electric furnace fusion of high purity alumina and high purity silica. Fused Mullite is a needle-like alumina-silica grain that has great features like:
- Low conductivity
- Excellent thermal shock resistance
- Excellent resistance to deformation under load
Fused Mullite is used in applications such as refractories for glass and steel industries, as kiln furniture, in investment casting as shell building materials, in spark plug bodies, etc.
Application:
Lightweight insulating castable is made by light weight refractory aggregate powder,binder and admixture
1. Binder- high purity calcium aluminate cement or aluminium dihydrogen phosphate
2. Refractory aggregate and power
3. fire clay (chamotte) based
4. high alumina based
5. mullite corundum based
6. silica based etc
Feature
*. Low bulk density and low thermal conductivity.
*. High mechanical strength.
*. Good thermal shock resistance,
*. Tiny linear variation,no cracking.
*. Resistant to scour and erosion,abrasion.
*. Good volume stability under high temperature.
