Note: Heating a Steel Susceptor for Glass Cutting

Objective:

To heat a steel susceptor to heat glass rods for a glass cutting application.

End Product:

Glass rods

Equipment:

Ambrell EASYHEAT 1.2 kW, 150-400 kHz induction heating power supply with a workhead and coil specifically designed for this application.

Materials:

Steel susceptor

Temperature:

2000 °F (1093 °C)

Frequency:

309 kHz

Testing:

A custom-designed single-position multiple-turn helical coil was built to generate the required heating for the 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. It was observed that it took 8 seconds to heat the sample to temperature and melt the glass. 

Benefits:

  • Speed: Induction met the client’s time objective for this susceptor heating application.

  • Repeatability: The client can expect the same result in the same amount of time every single time, which is ideal for their manufacturing process.

  • Safety: Induction has no open flame and is conducive to an automated manufacturing process
