Induction hardening Jaw Teeth of Carbon Steel

High frequency induction hardening Jaw Teeth of Carbon Steel surface process

Objective Successful hardening of the jaw teeth using induction. Equipment DW-UHF-6KW-I handheld induction hardening machine HLQ custom coil Materials Carbon steel jaw teeth supplied by the customer Key Parameters Power: 4 kW Temperature: Approximately 1526° F (830° C) Time: 10-15 sec
Process:
  1. A test coil was custom made for the application.
  2. The sample was fixed in position inside of the coil.
  3. Induction heating was applied to the teeth.
  4. The temperature of the sample was monitored during heating.
  5. Heat was applied until the hardening temperature was reached.
Results:
  • System managed to achieve its maximum power.
  • The tooth was heated to 830°C in 12 sec.
  • 930°C was reached in 20 sec.
  • The Curie point (around 770°C) is reached in 5 sec.
Conclusions:
  • System configuration –DW-UHF-6KW-I is suitable for the process.
  • Classic coil is also suitable for this application.
Recommendations:
  • Automation of the process can be achieved by moving either the HS with coil or the jaw in vertical direction.
  • Proper cooling systems have to be chosen. Cooling capacity – at least 4kW. Water-to-air system can be used, but it depends on the ambient operational temperature.
