| Abstract |
Compared with traditional blazing furnace, the Continuous Casting-Direct Rolling is an
advanced manufacturing steel technology, which can reduce energy waste, decrease pollution and
enhance efficiency. The characteristics of steels during induction heating are complex, the change
of material properties with temperature makes exact analysis methods very difficult to implement.
Therefore, a powerful computer aided numerical tool (i.e., finite difference analysis) is selected to
numerically model the induction heating process in this paper.
The mathematic model coupling with electromagnetic field and thermal field was established,
and it was solved by finite difference method (FDM), thus the slab temperature distribution and its
variation with time were obtained, and the characteristics in whole induction heating process were
studied. To validate the program feasible, the results were evaluated and compared with experiment
results, which showed that the simulation results are reliable and effective.
The skin effect in heating process from the two results was studied and demonstrated, the
temperature change caused by different parameters such as the induced power intensity and the
corner radian were also presented, which indicate that the slab temperature can be heated uniformly
through adjusting these parameters, thus the continuous casting slab can meet the rolling
requirement. |
