Cage rod ELEMENTS
Shaped heaters supported on ceramic plates
DESCRIPTION
Cage rod elements consist of metallic heaters and electrically non-conductive parts such as ceramic plates or spacers. These ceramic plates serve as insulation between heater and radiant tube. Also, holes and grooves in the ceramic plates receive the heaters, which in this way are kept electrically insulated from each other. The central rod is necessary to bind the ceramic parts together.
Heaters can be made from CrFeAl alloys or from NiCr alloys, depending on working conditions, temperature and atmosphere. Cold ends can be created by inserting ceramic parts between electrical connection and heating part. To prevent the heater from overheating, it is recommended to use one safety thermocouple per element or at least one per heating zone on furnace. Power depends on the element diameter, length and temperature.
APPLICATIONS
- Melting processes and casting plants
- Enameling, holding and other industrial furnaces
