Metal Filtration & Regernation Burners

Metal Filtration & Regernation Burners

Metal Filtration

Almost 50 million MT of aluminum are produced globally, serving primary end-use markets for transportation, packaging, engineering and construction.  Impurity and slag removal is a critical part of the ingot casting process.  Filter beds filled using tabular alumina products are an excellent choice to achieve necessary quality requirements while maintaining high throughput rates during production.

Regeneration Burners

Aluminum production requires a high amount of energy consumption and therefore furnace efficiency is critical.   Recycling furnace exhaust gases to pre-heat combustion air allows for higher fuel efficiency and reduction in emissions, particularly NOx and CO.  Tabular alumina support balls are used to facilitate the heat transfer process in order to maintain an efficient and robust system.

Almatis tabular aluminas for metal filtration and regeneration burner applications include various sized support media and crushed aggregates.  Our spherical and round support media can withstand challenging thermal cycling conditions and ensure efficient heat recycling.  The 18mm and 19mm media are also effective as the filter bed support base for metal casting.

Our crushed aggregates are the perfect compliment to filter bed supports because of their particle size distribution, minimal fines content and low levels of soluble ions.  For especially critical alloy castings where embrittlement is a concern, we offer an ultra-low soda product.  For processes where fines elimination is critical, washed products are also available.
