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