Note: Heating steel liners (engine head)
Objective:
Heat steel liners on the head of an engine to remove aluminum casing.
End Product:
Engine head
Equipment:
Ambrell 10 kW induction heating system, equipped with a remote workhead containing one 2.6μF capacitor.
An induction heating coil designed and developed specifically for this application.
Materials:
Steel, 80 mm ID x 190 mm (3.1 in x 7.5 in.)
Temperature:
650 °C (1202 °F)
Frequency:
81 kHz
Testing:
An internal 10 turn solenoid (bore) coil is used to heat the steel liner to 650 °C (1202 °F) in approximately two minutes. Pressure is applied to the outer aluminium skin to loosen it from the steel. A four position coil can be used to heat 4 liners simultaneously.
Benefits:
Precise direct heat to disengage the aluminium quickly and cleanly. The aluminium casing is recycled and reused thereby reducing scrap and cutting costs.
