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.

Method and apparatus for heat treating

A method for heat treating an aluminum part is provided. The method includes heat treating the aluminum alloy part with direct radiation from a source of infrared energy until the part attains a desired state of heat treatment. The method and apparatus further include monitoring of the part and controlling the intensity of the radiation source through proportional control in response to the measured temperature.

A process for heat treating a coating applied to an automobile body is disclosed. The process is carried out with apparatus which includes radiant heating elements for generating radiant heat in a predetermined path and convection heating elements for generating the flow of heated air. The method comprises the steps of positioning a freshly coated automobile body within the apparatus and heating the body with the radiant heat for a time sufficient to set the coating on Class A surfaces of the body. After the Class A surfaces are set, heated air is flowed around the body to heat the body and cure the coating on the Class A surfaces and the non-Class A surfaces.

Automotive coating treating process

A process is disclosed for heat treating a coating applied to an automobile body. The process includes the steps of radiant heating of a coating prior to convection heating.

Automobile coating heat treating process

An apparatus for heat treating a coating applied to an automobile body is disclosed. The apparatus includes radiant heating elements for generating radiant heat. Controls separately control zones of the elements in response to characteristics of the body to uniformly heat treat the body.
