The invention relates to a method for operating an electric arc furnace 00 having at least one electrode 104, the method comprising the following steps: introducing material that is to be melted in the form of an actual mass flow into the electric arc furnace and feeding electrical energy via at least one electrode into the electric arc furnace in order to melt the introduced material depending on a previously determined, necessary electrical energy input. The aim of the invention is to increase the production volume and the energy efficiency during operation of the electric arc furnace compared to such known methods. This aim is achieved, according to the invention, in that the necessary electrical energy input into the arc furnace is determined depending on the mass flow input into the furnace. 本发明涉及一种用于运行具有至少一个电极104的电弧炉00的方法，该方法具有以下步骤：将待熔化的材料以实际质量流量的形式输入到所述电弧炉中，并且经由所述至少一个电极将电能输入到所述电弧炉中，以便按照事先求取的所需的电能输入熔化所输入的材料。为了相对于这种已知的方法提高在电弧炉运行时的产量和能量效率，本发明建议，根据输入到炉中的质量流量来求取输入到所述电弧炉中的所需的电能输入。
