<p>A channel inductor with improved thermal and overall efficiency and reduced need for maintenance. The channel inductor comprises a closed-loop core (12), a primary winding (11) arranged around the core and a refractory lining (13) in which the winding and core is partly enclosed and in which an inductor channel (14) is formed. The inductor channel acts as a secondary winding when filled with an electrically conductive material. Detection means (21, 22) are arranged within the lining between the channel and the winding. The detection means are arranged for detection of metal penetration of the refractory lining.</p> |
