Abstract
A radiation furnace assembly for use in heating parts. The radiation furnace assembly includes a muffle having a top side, a bottom side, and a first side wall. The muffle defines a chamber with a main heating portion and a first side heating portion. Disposed adjacent to the muffle are top and bottom heating elements. A first control device is used to adjust the temperature of at least one of the top and bottom heating elements thus controlling the temperature within the main heating portion of the chamber. A first side heating element is disposed adjacent to the first side wall of the muffle. A second control device is used to adjust the temperature of the first side heating element independently of the top and bottom heating elements to increase the temperature within the first side heating portion of the chamber relative to the main heating portion.
