High Frequency Induction

The temperature field of mobile column is simulated, with the theory of high frequency induction heating and fourier heat conduction law , to analyze the change law of the temperature field with time, with different cladding parameters. The results show that the induction heating speed is mainly affected by power frequency of high frequency induction heating and cladding current. The higher frequency induction heating power is or the larger the cladding current is, the the faster the surface temperature of hydraulic prop is rising, the lower the inside-wall termperature and the less influenced the matrix is. The effect and the efficiency of cladding is comparatively superior when cladding frequency is 250KHz and current is 1160A.

High Frequency Induction

Quenching of steel 45 using high-frequency induction-heating (440000 Hz) with simultaneous shower water cooling was studied. The possibility of liquid-phase creation in the bulk (appr. 0.2 mm) in the material being treated in the absence of melting on the surface was clearly demonstrated by both numerical simulation of the temperature field in the material during hardening and experimental results
