| Abstract Scope |
Except effects of the modelling difference of the actual physical model and numerical model on the accuracy of calculation results , there are other parametric factors also play a role on the model accuracy. To more precisely calculate the magnetic field distribution and magnetic intensity, a numerical model of 250 mm × 280 mm cast billet is proposed to investigate the influence of load and mold copper resistivity on the magnetic intensity inside the mold under different current intensity and stirring frequency. The distribution of magnetic intensity along mold axis was output. There are little influence of the difference of no-load condition and casting condition on magnetic intensity. But with increase of stirring frequency, the degree of influence of load condition on magnetic intensity become increasingly evident. The magnetic intensity changed more obviously while changing copper resistivity of 20 °C and 160 °C. |
