Non-Ferrous Metals
Aluminum smelters, copper converters, and zinc roasters present unique refractory challenges due to low-viscosity molten metal penetration, fluoride attack, and specialized atmosphere requirements.
- Molten aluminum penetration into refractory grain boundaries causing spalling
- Fluoride vapor attack in aluminum reduction cell superstructures
- Matte and slag penetration in copper smelting furnace linings
- Oxidation-reduction cycling in roasting furnace atmospheres
- Non-wetting castables with alumina and phosphate binders for aluminum contact
- High-alumina bricks with low silica content to resist aluminum reduction
- Corundum-mullite bricks for copper converter and anode furnace linings
- Ceramic fiber insulation for secondary aluminum and holding furnace crowns
