Research Abstract

Molten pig iron with about 3 mass% was produced from mixed powder of magnetite and graphite during about 10 min by means of microwave heating with 2.45 GHz. The concentrations of impurities in pig iron were very low and especially that of phosphorous was one tenth in pig iron produced in blast furnace. It is realized that the refractories of reaction chamber should be cooled preventing them from absorbing microwave and melting itself and that microwave beams with weak power are concentrated to make high power zone at resources. 20kW furnace producing about 30kg of pig iron per day was successfully constructed and 120kW furnace producing 1 ton per day is now constructing.
