Induction heating graphite susceptorĀ for glassĀ reflow for X-ray tubes
Objective Heat graphite susceptor for glass reflow in the manufacturingĀ of x-ray tubes
Material Glass disc 0.98 x 0.12 ā (25 x 3mm), graphite susceptor,Ā stainless steel holder, Glass bell jar 5.9ā (150mm) OD
Temperature 1742 ĀŗF (950Āŗ C)
Frequency 80 kHz
Equipment ā¢ DW-HF-25kW induction heating system, equipped with aĀ remote workhead containing eight 0.3 Ī¼F capacitors for aĀ total of 2.4 Ī¼F
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A two turn helical coil is used for heating. Six graphiteĀ susceptors are placed in the nitrogen atmosphere with glassĀ discs and a stainless steel holder. In 32 seconds the requiredĀ temperature of 1742 ĀŗF (950Āŗ C) is reached causing the glassĀ to reflow & the stainless steel holder to melt through the glass.
Results/Benefits Induction heating provides:
ā¢ Increased production, customer currently heating 4Ā susceptors
ā¢ 50% lower energy consummation
ā¢ Even distribution of heating
