MW selective heating is suggested to be occurred in microscale; however, it’s impossible to measure a thermal gradient quantitatively in microscale by a conventional method. In addition, by conventional thermography, we cannot measure the materials temperature with different emissivity at the same time. Thus, selective-heating effect at the microscale is not understood well enough.
In this study, the authors verify the elective heating effect quantitatively using a high-resolution two-color thermography system.
This system can measure the temperature on each pixel with ▒2% accuracy with 8.8 Ám/pixel. At first, preliminary experiment was conducted using the powder mixture of Al2O3 and carbon rod. The two-color thermography exhibited the heated area like rod-shape, which size was correspond to carbon rod. The temperature gradient between carbon rod and Al2O3 was more than 2000 ℃/mm. In the presentation, the author plans to talk about other selective heating process such as an ironmaking process.
