The self-fluxing pellets containing coal possess an independent self-reducing and self-slag-making system. A high metallization rate can be achieved without external reduction condition at high temperature, and it looks like a micro-blast-furnace by itself. The essential condition to use it is to supply heat to the pellet rapidly and uniformly and keep it at a certain temperature. Microwave heating can meet the need of rapid and uniform heating. The results show that the temperature of the pellet with a certain weight increases as the microwave power increases. The heating rate of the pellet is increased from 9.17 K/min (5 kW) to 71.65 K/min (15 kW).
