| ![]() UltraFlex performing susceptor heating of alumina powder and graphite flakes using induction heaterThe induction heating application setup was performed per request of a leading research laboratory.
The laboratory required that a mixture of 90% non-conductive alumina powder and 10% graphite flakes which act as a susceptor be heated to 150-200 °C (302°–392° UltraFlex test lab engineers identified UltraFlex induction heating equipment from the UltraHeat W series as most appropriate for this heating scenario. UltraHeat W are advanced, cost-effective 5-15 kW induction heaters utilizing the latest switching power supply technology. They feature adaptive digital phase control providing very efficient operation in a wide frequency range. Heating small graphite flakes required high-frequency equipment and hence UltraHeat W was a great choice for the job. A helical coil was designed and used by UltraFlex to heat the mixture which was placed in a 0.5-inch (1.27 cm) diameter non-conductive tube. A K-type thermocouple connected to a temperature controller was used to evaluate the temperature throughout the entire heating process. At output power of 4 kW, it took only 10 minutes for the mixture to reach the target temperature of 160 °C (320°F). The temperature was then successfully maintained for 30 minutes. All customer requirements in this induction heating scenario had been successfully met. In addition, the heating process had been completely energy-efficient, cutting down the customer's costs. The induction heating also would ensure consistent results and repeatability, with no dependency on the operator skills. Finally, this would have been a completely green heating process, with no smoke, waste heat, and noxious emissions.
