Heat the threads of a 178mm (7”) long magnetic steel fastener to (900◦C) 1650◦F in less than 10 seconds.
Results / Benefits:
The induction heating system was used to verify material quality on steel screws. The customer is taking samples from production line (screws), heating them to (900◦C) 1650F using the Ultraflex 5 kW and dropping into a water quench for stress testing. Heat time can be further reduced if heating a smaller length of the fastener and by using an optimized coil design.
This allows for the customer to verify material quality and lot conformance, a vital component of the manufacturing process.
