The utility model provides a roller quenching inductor, which belongs to the induction heat treatment equipment field. The roller quenching inductor comprises a power frequency induction coil in which both the upper layer and the lower layer are controlled by an independent source, and an isolation layer is arranged between the upper layer induction coil and the lower layer induction coil. The utility model has the advantages that the quench hardening layer of the roller is deepened, the heat treatment quality at the through quenching layer position is ameliorated, the service life of the roller is prolonged, and the processing cost of the roller is reduced.
