| Abstract: | Combining the actual deposition process of billet with computation of the surface contour coordinates of deposition billet, the prediction model of deposition billet shape was established. It was found that the simulation results were equal to experimental ones, and the method could be more reasonable in simulation of deposition billet shape. Using finite element method, dynamic solidification process of deposition billet was characterized, and the temperature field was obtained with mathematical simulation... |
