A heater for rod-like products of the utility model is an electric heater for lathy rod-like products which are used by matching with middle (high) frequency transformers. The heater for rod-like products is mainly composed of a rack body whose one side is a heating inductor. The heater for rod-like products is characterized in that a drive shaft with a dentiform wheel is also arranged on the rack body. The inductor is designed as internal-external ring forms. Rod-like products which are to be heated are arranged on the dentiform wheel in order, the ends needed to be heated of the rod-like products pass the ring form inductor, and therefore, continuously heating work for rod-like products is accomplished. The utility model has the effects of simple structure, high working efficiency, and low intensity of labor. The constancy of the heating time and the temperature effectively improves the quality of the products.
