INFRARED FURNACE AND METHOD FOR INFRARED HEATING

摘要

In applying infrared heating to a mass production process of car body components, it is desirable that reduction in the temperature elevating time is compatible to energy saving and that an infrared furnace is simplified in structure. The infrared furnace includes a plurality of infrared lamps arrayed on one surface side of a work and a reflective surface provided on its opposite surface side. Outputs of the infrared lamps are locally adjusted, or intensity of the infrared rays incident on one work surface is locally adjusted by a member disposed between the infrared lamps and the one surface of the work. In this manner, variations in strength may be imparted to one and the same car part.
