Finite Element Simulation in Induction Heating of Billets in the Semi-solid

Semi solid metal forming processes have a great industrial interest for the production of various components because they have advantages such as reduction of macro segregation, reduction of porosity, low forming efforts and possibility of near net shape forming, etc. For the forming operation to work properly, it is important to heat the billet uniformly for the uniformity of solid liquid distribution and globular grain. It is also required to heat the billet as soon as possible. To satisfy these requirements, induction heating has been generally used for a long time. The induction heating process is analyzed using the commercial finite element software, anasys with the theoretical analysis of FEM to induction heating. The effect of induction heating including the variation of frequency of the inductor, time of heating, current intensity coefficient of the coil, size of the billet and size of the coil on temperature is analyzed.
