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