Induction Heating Inner of Steel Liners


Induction Heating Inner of Steel Liners With High Frequency Induction Heating Machine

Objective Heat steel liners on the head of an engine to remove aluminium casing.
Material Steel, 80 mm ID x 190 mm (3.1 in x 7.5 in.)
Temperature 650 ºC (1202 ºF)
Frequency 60 kHz
Equipment DW-HF-25kW induction heating system, equipped with a remote workhead containing one 2.6μF capacitor.
An induction heating coil designed and developed specifically for this application.
Process An internal 10 turn solenoid (bore) coil is used to heat the steel liner to 650 ºC (1202 ºF) 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.
Results/Benefits Induction heating provides:
• Precise direct heat to disengage the aluminium quickly and cleanly. The aluminium casing is recycled and reused thereby reducing scrap and cutting costs.
