Tategata microwave smelting furnace

Microwave smelting furnace, there is the supply port of the raw material at the top of the vertical furnace body, is vertically movable hearth member is provided on the furnace bottom. Around the furnace bottom, microwave irradiation chamber communicating with the interior of the vertical furnace body is provided. The inner surface of the microwave irradiation chamber is composed of copper or a copper alloy that reflects microwaves. Irradiation and vertical furnace body lower side of, the gap between the hearth member, the raw material is introduced into the microwave irradiation chamber, the raw material by microwave irradiation chamber high efficiency and the intensive microwave MW It is. Thus, the heated feedstock, iron ore is reduced molten pig iron is produced by a carbon source, from outlet molten pig iron is extracted. Thus, instead of the blast furnace ironmaking process, it is possible to produce molten pig iron with high energy efficiency, also it can be recovered noble metal from the so-called urban mines.
