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 Brass Contact

Induction Annealing Brass Contact For Crimping With RF Heating System Objective To anneal a small area of an electrical contact for crimping Material Brass female spade electrical contact with single transverse loop at end 0.5”(12.7mm) long, 0.25” (6.3mm) wide and 0.03” (0.8mm) thick, 1000ºF (538ºC)heat paint Temperature 1000ºF (538ºC) Frequency 310 kHz Equipment • DW-UHF-10kW induction heating system, equipped with a remote workhead containing two 1.0μF capacitors for a total of 0.5 μF • An induction heating coil designed and developed specifically for this application. Process A one turn hairpin coil is used to heat the electrical contact to 1000ºF (538ºC) in 1.5 seconds. The contacts are in strips at 0.75” (19mm) centers and will run continuously at a rate of 50’ (15.24m) per minute. Results/Benefits Induction heating provides: • Hands-free heating that involves no operator skill for manufacturing • Pinpoint accuracy • Consistent results

Annealing Brass Tubing With Induction

Annealing Brass Tubing,Copper Tube-Pipe With Induction Heating System Objective Annealing brass and bronze tubing for bending in a mandrel bender to form handrails Material • Brass tubes 1.5” (38.1mm) and 2” (50.8mm) diameter with 0.065” (1.65mm) wall thickness • Bronze tubes 1.5” (38.1mm) and 2” (50.8mm) diameter with 0.100” (2.54mm) wall thickness Temperature 1000 ºF (538 ºC) Frequency 300 kHz Equipment • DW-UHF-6kW induction heating system, equipped with a remote workhead containing two 0.5μF capacitors for a total of 0.25μF • An induction heating coil designed and developed specifically for this application. Process A twelve turn helical coil is used to heat an 8” (20.3cm) area 3” (7.6cm) above the end of the tube. Each of the four tubes require a different heat cycle and time to reach the required temperature. Please see the chart below for each tube. 1.5” 1.5” 2” 2” Results/Benefits Induction heating provides: • High efficiency, low energy costs • Precise and controllable placement of heat • Hands-free heating that involves no operator skill for manufacturing • Even distribution of heating, eliminating fractures during bending
