<p>The aim of the invention is to reduce the risk of destruction of the refractory material, especially by crack formation and corrosion. To this end, the invention relates to a unit, especially a melting and/or refining unit and/or a distribution system and/or a channel system for melted masses (30) that can be heated by conduction, especially glass melts. Said unit or system comprises a trough and at least one electrode (20), said electrode (20) being immersed in the melted mass (30) that can be heated by conduction, through an opening in a wall (10) of the trough. The inventive unit or system also has a device for reducing the local heat input into at least one region of the wall (10) adjacent to the electrode (20).</p> |
