Aluminum Refractories and Cathode Materials

McKeown supplies aluminum refractories for reduction cells and supporting furnaces, including cathodes, silicon carbide sidewalls, and the insulation systems that keep cell heat balance under control.

Reduction Cell Materials

Cell life depends on how well the cathode, sidewall, and joints resist sodium, bath, and molten aluminum over years of continuous operation. We supply each layer of the cell lining.

Cathodes and Carbon

Cathode blocks, anthracite blocks, and combo blocks for the cell bottom and transitions.

Silicon Carbide Sidewalls

Silicon carbide block for sidewalls that need high thermal conductivity and bath resistance.

Joint and Repair Materials

Silicon carbide mortars and castables to seal joints and repair sidewall sections.

Insulation and Backup Linings

The layers below the cathode control heat loss and protect the shell. We supply insulating brick, calcium silicate board, and fireclay and high-alumina brick for barrier and backup linings, with materials selected to hold their properties as the cell ages.

Planning a Cell Relining Program?

Send your cell design, relining schedule, and the lining materials you use today. We'll quote the complete package or only the layers you want to change.
