[0002] A medium frequency furnace is an induction furnace, and its operating frequency is usually between 50 and 2000 Hz. Its main function is to smelt metals. During the smelting process, the medium frequency furnace uses electromagnetic field induction to cause eddy current loss in the metal, thereby achieving the purpose of heating and melting. However, a large amount of smoke and dust will be generated, and a dust suction device needs to be added to the medium frequency furnace to prevent smoke and dust pollution. The existing medium frequency furnace dust suction device mainly uses the existing technology to generally cover the medium frequency furnace from above with a dust hood, and the dust hood is connected to the negative pressure device and the dust removal device through a pipeline.
