Abstract

1. A contact electrode for melting and heating furnaces with direct current plasma heating, in which a flow member (4) is provided in a bore (3) in the contact electrode (1) for the supply of a cooling medium, the flow member orifice being situated opposite the end face (6) of the contact electrode, characterized in that the orifice of the flow member (4), which is made from a corrosion resistant material, has a widening (5) such as to ensure uniformly intensive cooling of the end face (6) of the contact electrode (1).
