PURPOSE: A multi-purpose induction heating apparatus is provided to simplify a component structure by integrally casting and forming a preheat induction pipe and a postheat induction pipe. CONSTITUTION: A preheat induction pipe is integrally cast and formed in a preheat sense plate(1). A postheat induction pipe is integrally cast and formed in a postheat sense plate(2). The preheat sense plate and the postheat sense plate are divided and formed into a pair of symmetry structure. A coil unit(3) is closely arranged in the combining part of the preheat sense plate and the postheat sense plate. The postheat induction pipe and the postheat induction pipe are connected with an interlocked pipe.
