Note: End-forming top of aluminum oxygen tank
Objective:
Through heating the top 2 in (50.8 mm) of aluminum oxygen tank to form a rounded end with a hole for oxygen valve
End Product:
Oxygen tank
Equipment:
Ambrell 10 kW 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
Materials:
Aluminum oxygen tank with open end 2.25 in (57.15 mm) diameter, 0.188 in (4.8 mm) wall thickness
Temperature:
700 °F (371 °C)
Frequency:
171 kHz
Testing:
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 700 °F (371 °C).
