Design and implementation of high frequency inductor for simultaneous hardening

الملخص EN

This paper aimed at an investigating the design principles of coil and attempt manufacturing – high frequency induction heating coils which are important elements in heat treatment process and the cost of importing such coils are not readily available upon request.

A number of factors taken into consideration such as, dimension configuration of work- pieces, number of parts to be heated, temperature required, pattern of heat desired, applied frequency and level of power.

In this work a design of two coils of ( Ø 40 mm) and (Ø 60 mm) inner diameter.

The two coils are febracted from red copper.

This design improved that the greatest number of flux lines in a solenoid coil is toward the center of the coil, also prevent the cancellation of the field of magnetic coils.

The results show that the designed coils are of higher resistance (50 M Ω for Ø = 40 mm and 500 M Ω for Ø = 60 mm); also the coils resistances are (0.20Ω for Ø = 40 mm and 0.22 Ω for Ø = 60 mm)
