Case Study Scrap Remelting Plant U.S. – Hybrid Air / Oxy 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 For a U.S. scrap remelting plant, the ALTEK 30T Capacity Tilting Rotary Furnace (TRF) was installed as the primary melting unit, transferring metal to a 20T ladle furnace or a 150T side well melter. Production of foundry ingot met all international specifications. The TRF is fired by a nominal 6.0 MW hybrid oxy/air combustion system. At this plant, all types of scrap are melted, including castings (with and without iron attachments), taint tabor, profiles, swarf/chips, used beverage cans (UBCs) and drosses (pressed and loose). Energy released from organics on the scrap (plastic...
