Abstract: The new-style low heat-inertia fast-heating furnace for metal sample is developed based on its special need. The system adopts infrared lamps as heating radiation source, and achieves fast-heating and fast-cooling of sample in panel shape and bar shape by laying the lamps vertically and horizontally. This system has been proved to be effective by experiment to heat the metal sample on high-temperature and high-speed and quick cool through using infrared. It enlarges the using field of infrared and provides one new means for heat treatment of metals and science development.
