METHOD FOR COOLING A COOLING ELEMENT OF AN ELECTRIC ARC FURNACE, ELECTRIC ARC FURNACE FOR MELTING DOWN METAL ARTICLES, AND CONTROL DEVICE FOR AN ELECTRIC ARC FURNACE

摘要

The invention relates to an electric arc furnace for melting down metal articles, to a control device (9) for an electric arc furnace and to a method for cooling a cooling element (1) present in the electric arc furnace, in particular a cooling panel, wherein the cooling element (1) is cooled by means of a first cooling device (2), wherein the cooling is carried out by means of a phase transition of a coolant (K1) flowing through the cooling element (1) from a liquid phase into a gaseous phase. The capacity of an electric arc furnace can be increased by connecting a second cooling device (3) for the cooling element (1) before or during a temperature increase such that coolant (K2) fed from the second cooling device (3) additionally flows through the cooling element (1).
