High-temperature gas electromagnetic reversing device

The invention relates to a high-temperature gas electromagnetic reversing device. The device comprises an electromagnet, an iron ingot, low-melting-point molten metal, a filling room, a pipeline and accessory equipment, and the device can be used for high-temperature flue gas flow control and gas path switching in the fields of metallurgy, a glass furnace, a power plant and the like. The shape ofthe high-temperature gas electromagnetic reversing device is of a three-way reversing structure arranged symmetrically in the shape of W. Gas-out lower pipelines, filling rooms and gas upper pipelinesare arranged on the left side and the right side of a gas pipeline. The electromagnet is circlewise arranged on the outer side of a gas path pipeline and can rise and fall; the iron ingot is arrangedon the inner side of the gas path pipeline circlewise. The filling rooms on the two sides of the reversing device are filled with the low-melting-point molten metal. Accordingly, by means of an electromagnetic transmission dev
