The object is radiated by infrared rays, and after the object absorbs infrared rays, the radiant energy is converted into heat energy and heated.

Infrared is an electromagnetic wave. In the solar spectrum, outside the red end of visible light, it is an invisible radiant energy. In the electromagnetic spectrum, the infrared wavelength ranges from 0.75 to 1000 microns, and the frequency ranges from 3 x 10 to 4 x 10 Hz. In industrial applications, the infrared spectrum is often divided into several bands: 0.75 to 3.0 microns for the near-infrared region; 3.0 to 6.0 microns for the mid-infrared region; 6.0 to 15.0 microns for the far-infrared region; and 15.0 to 1000 μm for the far-infrared region Area. Different objects have different ability to absorb infrared rays, and even the same object has different ability to absorb infrared rays of different wavelengths. Therefore, in the application of infrared heating, it is necessary to select a suitable infrared radiation source according to the type of the object to be heated, so that the radiant energy is concentrated in the absorption wavelength range of the object to be heated, so as to obtain a good heating effect.
