Abstract

In a bi-level dual track 'solution' heat treatment and de-coring furnace for aluminum castings having a common hot gas treatment means for both separate tracks, the improvement of having all castings treated in the furnace move along both tracks rather than along only one of the respective tracks, yet with essentially the same overall treatment time. Also the addition of a relocating means in the form preferably of an elevator to move the castings from one track to the other.
