Induction Annealing

What is induction annealing?

This process heats metals that have already undergone significant processing. Induction annealing reduces hardness, improves ductility and relieves internal stresses. Full-body annealing is a process where the complete workpiece is annealed. With seam annealing (more accurately known as seam normalizing), only the heat-affected zone produced by the welding process is treated.

Induction annealing and normalizing delivers fast, reliable and localized heat, precise temperature control, and easy in-line integration. Induction treats individual workpieces to exact specifications, with control systems continuously monitoring and recording the entire process. Where is it used? Induction annealing and normalizing is widely used in the tube and pipe industry. It also anneals wire, steel strips, knife blades and copper tubing. In fact, induction is ideal for virtually any annealing task. What equipment is available? The suitable for induction annealing equipments including DW-MF,DW-HF and DW-UHF induction heater.

Induction Annealing Wire For Forming

Induction Annealing Wire For Forming With High Frequency Heating Machine

Objective Annealing a zinc wire prior to forming a special high velocity air rifle pellet Material Zinc wire 0.18” (4.5mm)dia Temperature 572 ºF (300 ºC) Frequency 300 kHz Equipment •DW-UHF-6kW-III induction heating system, equipped with a remote workhead containing two 0.33μF capacitors for a total of 0.66μF • An induction heating coil designed and developed specifically for this application. Process A fourteen turn coil is used to heat 3.9” (100mm) of zinc wire. The wire is placed in the coil for 5 seconds to reach the desired condition just prior to the forming process. Results/Benefits Induction heating provides: • Reduces hardness of pellets to prevent damage to the forming dies • Reduced production time • High efficiency, low energy cost • Fast and controllable heat • Hands-free heating that involves no operator skill for manufacturing
