Abstract

The development of a rapid uniform heating process for blanks is needed to perform hot stamping processes. To solve the problem of inhomogeneous temperature distribution in conventional induction heating systems, a heating block has been added to an induction system and investigated to determine if it can achieve rapid and uniform blank heating. To characterize the effects of incorporating the heating block, the temperature distributions of various coil geometry have been experimentally analyzed. The results show that the proposed induction heating system makes it possible to achieve rapid and uniform blank heating, which is used to conduct stable hot stamping. The mechanical properties of a hot stamped part confirm that the proposed heating method is a feasible alternative method for hot stamping products, and that it yields excellent results. This system for the reduction of heating time requires less installation space compared to a conventional electric furnace and achieves uniform heating, which results in improved product quality and reduced manufacturing costs.
