Metaullics Systems Delivers Process and Cost Benefits for Hayes Lemmerz Italy
Printed with permission of Hayes Lemmerz, Italy.
Last year, Hayes Lemmerz, Italy, changed their melting furnace, and at the same time equipped the new one with a Metaullics T35SD circulation pump and a 30 inch LOTUSS for submerging the metal chips. The equipment installation was discussed with and supplied by Pyrotek’s Metaullics Systems Europe, under the guidance of Italy-based technical sales engineer, Massimiliano Doria.
The company had previously used a vertical screw conveyor for submerging light scrap with no circulation provided. With the previous process equipment an 89% recovery rate had been realised. Following the installation of the Metaullics Systems equipment Hayes Lemmerz has reached an average recovery rate of 96%, representing a huge economical saving.
The savings of this installation can be illustrated by a simple calculation. Considering the improved recovery rate, the furnace produces 13,000 t / yr of aluminum, and the new equipment system boosts the recovery rate by 6%. This calculation represents a saving of some 780 t of aluminum in one year. At the actual aluminum LME price this equates to savings of USD$1,950,000 per year. Also, deducting operation and maintenance costs, Hayes Lemmerz has accrued a net saving of approximately USD$1,500,000 per year (considering also the reduced dross they are no longer selling).
Additional beneficial factors include the following items.
• Savings in burner power consumption
• Improved production rate (less time wasted for skimming of dross)
• Safety and security of workers
Hayes-Lemmerz has also equipped their furnaces with Metaullics Systems pump and LOTUSS in the Czech Republic, Thailand, Mexico, Turkey, South Africa and the USA.
In conclusion, Pyrotek’s Metaullics Systems Division is justifiably proud of this installation, which once again demonstrates their reliability, professionalism and the importance of installing a good circulation and submerging system.
