Document Type and Number:
Japanese Patent JP5683725
Kind Code:
B2
Abstract:
The present invention relates to a method and device for controlling a melting and refining process in an electric arc furnace for melting a metal, wherein the electric arc furnace comprises molten and solid metal and, a slag layer on the surface of the molten metal, wherein an electromagnetic stirrer is arranged for stirring the molten metal. The method comprises calculating/determining masses of the molten and solid metal at a point of time, wherein the calculation is based on initial values of the molten and solid metal, an arc power supplied to the electric arc furnace, and temperatures of the molten and solid metal (100), determining a stirring power based on the calculated/determined masses (200), and supplying the determined stirring power to the electromagnetic stirrer (300).
