METHOD AND APPARATUS FOR MANUFACTURING EXTRUDED STRUCTURAL PROFILES FROM ALUMINUM BASED METAL SCRAPS
摘要
<p>Aluminum or aluminum alloy scraps or wastes are broken into chips and extruded under a high temperature to produce extruded structural profiles. The method is characterized by the fact that the interior of the extruder is evacuated prior to or simultaneously with the extrusion step so as to exhaust air entrapped in the body of the chips. There is also disclosed apparatus suitable for performing the method.</p>
