Abstract

Using a furnace focused 8 microwave beams of 16 kW at 2.45 GHz to the center of applicator, 9149 g of molten pig iron was produced from 14049 g of the mixed powdery resources of Romeral iron ore and graphite during 780 min under N2 gas. The yield of pig iron was 99.3%. The resources was intermittently supplied with the rate of 35 g/min for 20 min. By each supply of resources of 700 g, temperature rapidly decreased and increased to near 1300°C and molten pig iron poured out from a reaction chamber with generating white light emission.
