摘要:
A system and method for developing a heat treatment process using a model radiative-heating oven, which repeatably and accurately simulates an industrial heat treatment system. In order to simulate the industrial heat treatment system, the model radiative-heating oven uses a variety of scaling factors, such as heating density parameters. The model radiative-heating oven also may have a quickly openable and closable object carrier, which facilitates a timely start and end of a desired heat treatment process. An oven temperature stabilizer also may be provided for thermally stabilizing the model radiative-heating oven prior to the desired heat treatment process. The present technique also may utilize a variety of heat profile controls, such as time, temperature, and power levels, to provide the desired heat profile in the heat treatment process.

A plurality of treatment station includes a plurality of heat treatment portions and staging portions. The staging portions utilize non-contact temperature sensors to measure an intensity of infrared radiation emitted from a part to be heat treated. A plurality of wavelengths of infrared energy emitted from a part are read with the wavelengths used as inputs to an empirical equation to calculate an apparent actual temperature of the part. The staging portions and the heat treatment portions are shielded to prevent infrared energy from the heat treatment portion from interfering with the accuracy of the staging portions.

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.

A commercial scale system and process for chemically modifying wood and then heating the chemically-modified wood. The system/process separates the chemical modification step from the heating step by utilizing two different vessels for the modification and heating steps. The system and process can, in certain situations, include a containment room for preventing escape of vapors from a chemical wood modification reactor, a wood heater, and/or a chemically-modified bundle of wood as the bundle is transported from the wood modification reactor to the wood heater.
