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 removeย aluminium casing.
Material Steel, 80 mm ID x 190 mm (3.1 in x 7.5 in.)
Temperature 650 ยบC (1202 ยบF)
Frequency 60ย kHz
Equipment DW-HF-25kW induction heating system, equipped with aย remote workhead containing one 2.6ฮผF capacitor.
An induction heating coil designed and developed specificallyย for this application.
Process An internal 10 turn solenoid (bore) coil is used to heat the steelย liner to 650 ยบC (1202 ยบF) in approximately two minutes.
Pressure is applied to the outer aluminium skin to loosen itย from the steel. A four position coil can be used to heat 4 linersย simultaneously.
Results/Benefits Induction heating provides:
โข Precise direct heat to disengage the aluminium quickly andย cleanly. The aluminium casing is recycled and reusedย thereby reducing scrap and cutting costs.
