PURPOSE:To contrive to improve the uniformity of the surface temperatures of objects to be heated using the title device by a method wherein the device is provided with heat-resistant thin plates, which are set up in the heat-resistant container in such a way as to surround the periphery of the supporting stand, whereon the objects to be heated are disposed, and are turned into the secondary heat sources without allowing light to transmit. CONSTITUTION:This infrared ray lamp heat treatment device is provided with heat-resistant thin plates 11, which are set up in a heat-resistant container 3 in such a way as to surround the periphery of a supporting stand 4, whereon objects to be heated are disposed, and are turned into the secondary heat sources without allowing light to transmit. By this constitution, the thin plates 11 to be irradiated with the rays of light of infrared ray lamps 6 are turned into the secondary heat sources and the objects to be heated are uniformly heated. Accordingly, the uniformity of the surface temperatures of the objects to be heated is improved and even when the objects to be heated are held vertically or slantingly, the uniformity of the surface tempertures is not deteriorated. |
