Anotácia

This practice covers the controls required and standards for extrusion press solution heat treatment for 6xxx and 7xxx series aluminum alloys. For alloys such as 6005, 6005A and 6105 alloys, this practice is an alternative to solution heat treatment in a furnace. This practice only applies to extrusion press solution heat treatment for aluminum alloys and does not cover precipitation hardening (aging) processing. The alloy billets shall be preheated prior to being extruded. Heating methods shall include, but not limited to, induction, flame impingement, or forced air. Pertinent control points shall include billet or log temperature in the heating equipment, billet temperature upon being charged into the press container, container temperature, ram speed, profile configuration, extrudate temperature upon exiting the press platen, extrudate temperature at quench entry, quench media temperature, and quench rate.
