Typical application
ARKAL 65 V is adapted to superstructure application with complex and large shape. Used in:
- working end and wide feeder superstructure for various type of glasses,
- flat arches in canal and spout lip area for float glass furnaces.
Can sustain more severe operating conditions in term of temperature and creep resistance compared to ARKAL 60 V.
