Induction Hot Plate

High Frequency Induction Hot Plate with a Tin Coating for Flow-Melting  Objective Heat a carbon steel plate coated with tin to 450 ºF (232 ºC) for flow-melting Material 7.9” (200mm) x 4.7” (120mm) steel plates with a tin layer of 100 to 1000nm thickness, temperature sensing paint, water for quenching Temperature 450 ºF (232 ºC) Frequency 350 kHz Equipment • DW-UHF-20kW induction heating system, equipped with a remote workhead containing two 0.5μF capacitors for a total of 0.25μF • An induction heating coil designed and developed specifically for this application. Process A nine turn “Dog Bone” style coil is used for the flow-melting process. The tin coated carbon steel plate is placed in the coil for 1.34 seconds to uniformly reflow the tin coating. The plate is then quenched in cool water to retain sufficient free tin at the surface. Results/Benefits Induction heating provides: • Uniform heating • Rapid focused heat
