Induction Annealing Aluminum PIpe

Induction Annealing Aluminum PIpe With High Frequency Induction Heating Machine

Objective Annealing aluminum fuel tank fill neck to 650 ยบF (343 ยบC)
Material Aluminum fill neck 2.5โ€ (63.5mm) diameter, 14โ€ (35.5cm) long
Temperature 650 ยบF (343 ยบC)
Frequency 75 kHz
Equipment โ€ขDW-HF-45kW induction heating system, equipped with aย remote workhead containing eight 1.0ฮผF capacitors for aย total of 2.0ฮผF
โ€ข An induction heating coil designed and developedย specifically for this application.
Process An eight turn helical is used to heat the tube for annealing. Toย anneal the full length of the tube, the tube is placed in the coilย and heated for 30 seconds then rotated and the bottom half isย heated for an additional 30. The tube is then bent while hot toย prevent cracking.
Results/Benefits Induction heating provides:
โ€ข High efficiency, low energy cost
โ€ข Fast, controllable and repeatable process
โ€ข Prevention of cracks
โ€ข Hands-free heating that involves no operator skill forย manufacturing
โ€ข Even distribution of heating
