A new Bolt Heater
that pursued outstanding operability was developed!
PRINCIPLE OF HIGH-FREQUENCY BOLT HEATER Using a conventional thermocouple heater and measuring hole, insert a water-cooling type work coil.The alternating magnetic flux generated from the work coil by the alternating current penetrates into the bolt, by which very high eddy current is induced within the bolt, and the bolt is heated by its Joule heat.
