ABSTRACT:
A carburizing apparatus that can reduce cost and shorten the carburizing time is provided. A single coil for raising temperature, a plurality of coils for soaking, and a conveying mechanism that conveys a treatment object from a position of induction heating with the coil for raising temperature to positions of induction heating with the coils for soaking are provided inside a container for carburization treatment. The rated capacity of a power source for raising temperature that is connected to the coil for raising temperature is higher than the rated capacity of a power source for soaking connected to the coil for soaking.
