Abstract

See full text

An infrared furnace system provides for adjusting the amount of time a workpiece spends in a respective section of the furnace while at the same time minimizing the footprint, i.e., the amount of floor space that the furnace uses. Various embodiments allow for optimizing the required thermal duration of each section which then also optimizes the heating and/or cooling profile within each section. Transfer conveyors are provided to transfer a workpiece from one conveyor operating at a first speed to a second conveyor operating at a second speed, different from the first speed in order to prevent damage to the workpiece. Rollers are provided to support the workpiece and to maintain a proper orientation. A heating lamp support assembly provides power to the lamp and facilitates exchange and replacement of the lamp. An air delivery system provides process gas maintained at the correct temperature. An exhaust system provides air flow with improved turnover and reduced noise considerations. Infrared heating lamps are cooled by providing gas flow across the end terminals. The wavelength of light emitted by the heating lamps is adjusting by controlling parameters of the process gas being introduced into a section of the furnace.
