Description

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
