Abstract

In order to recover metallic components from the mill scale generated in the hot rolling process of stainless steels more efficiently, a carbothermic reduction of the mill scale using microwave heating was carried out. The mixture of the mill scale and graphite particles was heated at a very rapid heating rate of 100 °C/min via microwave heating. As a result of this process, self-assembled metallic droplets of 1 mm to 5 mm in diameter were produced in less than 15 min.
