<p>The invention relates to a channel type induction furnace having at least one inductor and closed channels, including side channels, interconnected at the bottom, possibly via a bottom channel joining said channels, and possibly also a central channel extending between the hearth and the bottom channel, especially designed for aluminum, copper or other non-ferrous metals or non-ferrous alloys. The channel type induction furnace according to the invention is characterized in that the height of the channel in a plane through the longitudinal axis of the primary coil is at least 4x delta , where delta is the depth of penetration into the melt of the current induced in the channel, and the width of the channel is at least 6x delta .</p> |
