Induction Heating Aluminum Pipe For End Forming With High Frequency Induction Heater
Objective Through heating the top 2โ (50.8mm) of aluminum oxygen tankย to form a rounded end with a hole for oxygen valve
Material Aluminum oxygen tank with open end 2.25โ (57.15mm)ย diameter, 0.188โ (4.8mm) wall thickness
Temperature 700 ยบF (371 ยบC)
Frequency 71 kHz
Equipment โข DW-HF-45kW induction heating system, equipped with aย remote workhead containing two 1.5ฮผF capacitors for aย total of 0.75ฮผF
โข An induction heating coil designed and developedย specifically for this application.
Process A five turn helical coil is used to heat the open end of theย oxygen tank. The tank is heated for 24 seconds to reach 700ยบF (371 ยบC).
Results/Benefits Induction heating provides:
โข Uniform through heating
โข Fast, energy-efficient heat
โข Fast, controllable and repeatable process
โข Hands-free heating that involves no operator skill forย manufacturing
