Abstract
An apparatus for metallurgically heat treating a plurality of discrete individually movable aluminum alloy parts includes a plurality of successive stations for heat treating the parts. The plurality of stations are arranged in a line of travel. Infrared radiation lamps are provided at each station. A conveyor mechanism places and holds a part in a station for heat treatment. The conveyor moves the part to a subsequent station for further heat treatment. The conveyor mechanism holds the part stationary relative to the line of travel while the part is in a station being heat treated.
