Title:
熔融プロセスを制御するための方法及び制御システム
Document Type and Number:
Japanese Patent JP2014519551
Kind Code:
A
Abstract:
A method of controlling a melting process in an electric arc furnace for melting a metallic material. By means of the present disclosure it is possible to minimize desired process properties such as the melting time or the total power consumption of the melting process. The method includes the steps of receiving or collecting measured data of at least one process variable, determining the current state of the process, performing an optimization of the melting process, determining a process input based on the result of the optimization, and controlling the melting process by means of the process input. A control system is also presented herein.
