Induction Heating
(2010) Qadri Mayaleh; AbdelRahman Abbass; Samer Mayaleh
As we know the demand for better quality, safe and less energy consuming products is rising. Products using IH include electronic rice cookers , pans and industrial heating machines. Safe, efficient and quick heating appliances attract more customers.The induction hardening machines are utilized in the industries which modify machine parts and tools needed to achieve high ware resistance. This study describes the model of induction heating process design of inverter circuit and the results of induction surface hardening of heating coil. In the design of heating coil, the shape and the turn numbers of the coil are very important design factors because they decide the overall operating performance of induction heater including resonant frequency, Q factor, efficiency and power factor. The performance will be tested by experiments in some cases high frequency induction hardening machine.
