A method and a device have high energy efficiency and high descaling performance, with which high-quality rolling stock can be produced. In a method in which the rolling stock is heated in an induction furnace and subsequently descaled, before the rolling stock is rolled in a rolling stand or rolling relay, the heated rolling stock is descaled by at least one rotating water jet from a rotary descaler; then at least one temperature of the descaled rolling stock is respectively recorded by a temperature measuring instrument and delivered to a controller; and the controller determines at least one control parameter with the aid of a control rule and by taking into account a setpoint temperature, and delivers it to a control component, at least one inductor of the induction furnace being driven so that the temperature of the descaled rolling stock corresponds as far as possible to the setpoint temperature.
