Features of the Use of Induction Heating in «Semi-Solid Metal Forming»

It is important to get the homothermal temperature. Temperature variability over the cross-section affects the distribution of the liquid phase in the blanks. The induction heating the primal blank to the solid-liquid state with an accurate temperature field formation meets the criteria to a greater extent. However, there are a number of difficulties during the implementation of this type of heating, as it is necessary to choose the current frequency optimally and determine the design and operating modes of the induction heater. The mathematical modeling plays a significant part in the successful design of the induction heating system. The research presents the studies of blanks to a liquid-solid state. Power control modes and heating dynamics for blank are obtained. A method to increase the productivity of a single-inductor system is proposed. For doing this it is proposed to introduce smooth power control.
