Case Study Dross Processing Plant Middle East Gulf Region – Air Fuel Overview Investments in scrap re-melting facilities are paying off across the entire spectrum of the aluminum industry, including primary and secondary cast houses and the foundry/die casting sectors. Recycling utilizes resources, and scrap is a low-cost feedstock alternative compared to primary reduction, providing high energy savings. The key profit drivers for scrap melting are low energy, high productivity and, most notably, maximum metal recovery. As scrap is a highly complex and varied material, to achieve desired outcomes, the furnace and its process technology must be tailored to the individual operator’s specific needs. ALTEKadvance: Solutions In January 2020, ALTEK acquired Melting Solutions Limited, gaining its years of experience and a proven track record melting scrap and delivering many cost-effective melting plants worldwide for all types of scrap. Today, the ALTEK Tilt Rotary Plants deliver outstanding outcomes for customers, achieving exceptional results on both oxy fuel and air fuel furnaces

Case Study Approach At a dross handling plant in the Middle East’s Gulf Region, the ALTEK 25T Tilting Rotary Furnace (TRF) (30,000T per year) processes dross from one of the world’s largest primary aluminum smelters. It is fired by a single air/natural gas burner system, with a nominal firing rate of 5.4 MW. The rotary body has an internal volume of 40 m3, an internal door opening of 2m, and a liquid capacity of 11 M3, which is a nominal capacity of 25 tonnes. The furnace is primarily used for melting primary drosses with a capability of more than 30,000 tonnes of dross per year. The burner is...
