Abstract
An apparatus for melting metals whose melting temperature is below 1000° C. may have a device for forming a plasma arranged on a melting furnace. The device is connected to an electrical voltage supply and to the device at least one first supply for a plasma gas, with which the plasma can be formed, and is designed, dimensioned, arranged and/or aligned in such a way that the formed plasma is arranged at a distance from the metal as the material to be melted, and in this case a hot gas stream can be formed with the plasma, which hot gas stream is aligned in the direction of the material to be melted, and a melting tank or crucible is arranged in the melting furnace to receive the molten metal.
