The object of the invention is a device for purifying liquid metal from nonmetallic inclusions through the creation in it of electromagnetic forces directed downward through the placing of the metal between the poles of an electromagnet and the applying to it of an electric current. For the purpose of continuously processing the metal and applying an agitation to it in the extreme areas the device is designed in the form of a rectangular conduit into the ends of which there is introduced a current carrying bar representing the secondary winding of a transformer and having a cross section not less than the cross section of the conduit. To apply the current to the liquid metal by induction it is provided with a ring-type closed channel filled with liquid metal united with the ends of the conduit and embracing the closed magnetic conductor with the primary winding placed on it. For the purpose of extinguishing the electromagnetic pressure and using the device as electromagnetic pump, the output piping of the conduit is designed in the form of a U-shaped channel. The metallostatic pressure in the top elbow compensates the electromagnetic head developed by the device. Author
