RECYCLING OF ALUMINIUM SCRAP BY THE DIRECT AND CONTINUOUS CONVERSION INTO EXTRUDED PRODUCTS.

Objective

THE AIM OF THIS RESEARCH IS TO STUDY AND PROVE THE INDUSTRIAL VIABILITY OF AN ALTERNATIVE PROCESS OF RECOVERY OF METALLIC SCRAPS OF ALUMINIUM AND ITS ALLOYS BY DIRECT CONVERSION INTO EXTRUDED PRODUCTS OF VARIOUS TYPE BY :
- REDUCING THE LOSSES INVOLVED IN THE CONVERSION OF SCRAPS
- ELIMINATING THE POLLUTING DROSSES PRODUCED DURING REMELTING
- REDUCING THE RECOVERY COSTS OF SCRAPS
- POTENTIAL DEVELOPMENT OF NEW MATERIALS BASED ON EXTRUSION PRODUCTS FOR VARIOUS INDUSTRIAL APPLICATIONS.
A new aluminium recovery process by direct conversion of scraps into extruded products without the remelting step was evaluated. The technology developed was confirmed as being both suitable for producing continuous extruded products and viable for application in industry.
THE PROCESS WILL BE DEVELOPED IN THE FOLLOWING FUNDAMENTAL PHASES:

- STUDY OF ALREADY AVAILABLE SCRAPS (ALUMINIA) AND IDENTIFICATION;
- STUDY OF THE METHODS OF ABOVE SCRAPS COMMINUTION (BLADE AND HAMMER MILLS TYPES) TO OBTAIN OPTIMUM CHARACTERISTICS;
- STUDY OF CLEANING THE SCRAP OR GRANULE BY HEATING;
- DEVELOPMENT OF THE CONFORM EQUIPMENT AND PROCESS TOOLS;
- PILOT PRODUCTION (USING HOLTON TOOLS) PROVING TRIALS TO ESTABLISH TECHNICAL AND ECONOMIC VIABILITY;
- CHARACTERIZATION OF THE OBTAINED EXTRUSIONS;
- STUDY OF THE POSSIBILITY OF USING SUCCESSIVE TREATMENTS OR PROCESSING.
