Method and device for preparing hot-rolling stock

摘要

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.

1. A method for preparing hot-rolling stock, the method comprising the steps of:
heating a rolling stock in an induction furnace; descaling the heated rolling stock; rolling the descaled rolling stock in a rolling stand or a rolling relay, wherein the heated rolling stock is descaled by at least one rotating water jet from a rotor of a rotary descaler; recording, by a temperature measuring device, at least one temperature of the descaled rolling stock, and delivering the at least one temperature to a controller; and determining, by the controller, at least one control parameter with the aid of a control rule and by taking into account a setpoint temperature, and providing the at least one control parameter 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.
