The top electrode – type forehearth is a proven tool for direct energy input into feeders and forehearths with a covered glass surface.
It consists of a media connection part, a glass-coated water-cooled holder and a molybdenum electrode. They are only installed vertically from above in the forehearth.
The immersion depth depends on the application. For energy input, electric current is conducted directly via the electrode through the molten glass to a counter electrode.
FEATURES
Easy handling
Firmly established in electrical heating of speciality glasses
Produces very good temperature distribution in the melt
