ALUMINIUM INGOTS PRODUCTION

CASTING FURNACE CHARGING

Studimpianti Sei can supply, also with the ìturn keyî formula, plants for the storage and treatment of the raw materials, the automatic weighing of them and the loading of the smelting furnaces.
As far as the loading of smelting furnaces is concerned, our plants can include:

• The deferrization of the various aluminium scraps and the storage of them by belt conveyor and pocket elevators into the various storage silos.
• The crushing of the scraps coming from raw materials smelting into the furnaces, the deferrization, the screening and the storage of them into the various silos by belt conveyors, bucket elevators and screw conveyors etc.
• The storage into the silos by belt conveyors and bucket elevators.
• The automatic weighing of the stored raw materials by load cells and the conveying of them to the railway vibrating trolley for furnace charging by belt conveyors and pocket elevators.
• The smelting furnace loading by belt conveyor or travelling vibrating feeder.

All the above mentioned sequences are realised automatically (except for loading of the raw materials by loading shovel and the furnace loading which requires the operatorís input) by: industrial keyboard - monitor with video pages - microprocessor and PLC.
