High FrequencyĀ Induction Hot PlateĀ with a Tin Coating for Flow-MeltingĀ
Objective Heat a carbon steel plate coated with tin to 450 ĀŗF (232 ĀŗC) forĀ flow-melting
Material 7.9ā (200mm) x 4.7ā (120mm) steel plates with a tin layer ofĀ 100 to 1000nm thickness, temperature sensing paint, water forĀ quenching
Temperature 450 ĀŗF (232 ĀŗC)
Frequency 350 kHz
Equipment ā¢ DW-UHF-20kW induction heating system, equipped with aĀ remote workhead containing two 0.5Ī¼F capacitors for aĀ total of 0.25Ī¼F
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A nine turn āDog Boneā style coil is used for the flow-meltingĀ process. The tin coated carbon steel plate is placed in the coilĀ for 1.34 seconds to uniformly reflow the tin coating. The plateĀ is then quenched in cool water to retain sufficient free tin at theĀ surface.
Results/Benefits Induction heating provides:
ā¢ Uniform heating
ā¢ Rapid focused heat
