Vermiculite Refractory Bricks For Aluminium Tanks (VM-1250)
Description:
Vermiculite Refractory Bricks are designed exactly for the aluminum insulation industry especially aluminum electrolysis cells.
We have RG Vermiculite insulation boards in different densities, LYRG-VM1250, LYRG-VM1100, LYRG-VM550, LYRG-VM450. Both of them are non-combustible under the maximum service temperature of 1100°C , and combine high strength with low-thermal conductivity, So they are highly resistant to cryolite penetrations and fluorides, and not wetted by molten aluminum
Main Feature
The Main benefits of RG Vermiculite insulation boards are:
1. Reduce CO2 footprint and power consumption
2. Increase reduction cell life, hence reducing the cell rebuild frequency
3. Increase production flexibility
4. Reduce relining time through customized pot sets and increase production
5. Offers resistance to attack from vapor-, molten cryolite and -aluminum
