Hertwich Engineering, Austria, has commissioned a batch homogenizing facility and a cooling station at DUBAL, United Arab Emirates. The homogenizing plant is the third of its kind to be built by Hertwich within the aluminum smelter complex of the customer.
The batch homogenizing facility is designed for extra-fast heating of billets. A reversing air concept and regulation by flaps accelerates the heating by an estimated 20 %, and achieves improved temperature uniformity. The plant is fully automated and is regulated via measured air and metal temperatures. The same concept also provides more efficient cooling in the air-cooling station.
