Induction Heating a Steel Susceptor for Glass Cutting

A client needed to heat a steel susceptor in order to heat glass rods for a glass cutting application. They decided to take advantage of free parts testing from THE LAB at Ambrell. Given their requirements, Ambrell's team of application engineers determined that an Ambrell EASYHEAT^TM 1.2 kW, 150-400 kHz induction heating power supply with a custom-designed single position multiple-turn helical coil would be the optimal solution for this application.

Initial tests were conducted to optimize the power delivered to the part. A pyrometer was used to measure the temperature of the part until it reached the target temperature. It was observed that it took eight seconds to heat the sample to 2000 °F (1093 °C) and melt the glass. This met the client's objectives.

THE LAB confirmed the viability of this application. Induction offered fast, safe and repeatable heating that would work well for susceptor heating for glass cutting.
