Induction Annealing Copper Tubes

Simultaneously Induction Annealing Copper Tubes

Objective Uniformly heat two copper tubes simultaneously to 800°F (426°C) in under 10 seconds with induction heating.

Equipment DW-HF-45kw induction heater Helical coil Material • Two copper tubes – OD: 0.69’’ (1.75 cm) – ID: 0.55’’ (1.40 cm) – Length: 5.50’’ (14.0 cm). Key Parameters Power: 35kW Temperature: 842°F (450°C) Time: 7sec

Process:

1. The two copper tubes were placed together in the coil.
2. Induction heat was applied for 8s.

Results/Benefits:

• Improved process control for uniform heating to a desired temperature
• Power on demand and rapid, consistent heat cycles
• Technology without pollution, which is both clean and safe
