Refractories Applications - Primary Aluminium
Process information : Reduction Cell Side wall
Reduction
cell wall designs are engineered to allow a controlled freeze layer of
cryolite to develop and contain the cell contents during the reduction
process. In addition to the corrosion resistance linings have also to
withstand the effects of local electromagnetic stirring, removing the
frozen layer and exposing the side walls to molten cryolite and aluminium
Process temperatures circa 960°c
Chemical corrosion by cell contents
Long expected campaign life circa 2500 days
Localised oxidation at the top of the cell and behind the side wall lining
Side wall heat dissipation is important to maintain cell efficiency
Localised abrasion and erosion
