    • The invention relates to a method for controlling a metallurgical plant (12) in an open-loop and/or closed-loop manner. In order to enable simple, robust, and economical open-loop and/or closed-loop control of a metallurgical plant (12), the method according to the invention comprises the following steps: detecting a metal microstructure of a metal product after the performance of a processing step on the metal product by means of the plant (12) (step 24); producing at least one microstructure characterization characterizing the detected metal microstructure (step 25); comparing the produced microstructure characterization with at least one specified limit criterion (step 26); and performing a further processing step (27), which follows the processing step, on the metal product by means of the plant (12) only if the produced microstucture characterization meets the specified limit criterion.

    • The invention relates to a method for operating an arc furnace (1), wherein the arc furnace comprises a receiving vessel (2) for molten material (3) and also at least one electrode (4), wherein the electrode (4) is arranged on a carrier arm (5) and is held thereby, wherein a foamed slag former (C) is introduced into the receiving vessel (2) in order to form a layer of foamed slag (6) with a height (h) on the molten material (3). In order to determine the foamed slag height in an improved manner, and to thereby optimize the feed of the foamed slag former, the method comprises the following steps: a) determining a functional relationship (h = f (a)) between the oscillations of the electrode (4) or of the carrier arm (5) during operation of the arc furnace (1) and the height (h) of the foamed slag (6) by measurement; b) operating the arc furnace (1), the oscillations of the electrode (4) or of the carrier arm (5) being measured and, on the basis of these measured values, the height (h) of the foamed slag (6) being determined using the functional relationship (h = f (a)) determined in step a).
    • 本发明涉及一种用于操作电弧炉(1)的方法,其中电弧炉包括用于熔融材料的接收容器(2)和至少一个电极(4),其中电极(4)被布置 在承载臂(5)上并被保持在其中,其中将泡沫炉渣形成器(C)引入接收容器(2)中,以形成在熔融物上具有高度(h)的泡沫炉渣层(6) 材料(3)。 为了以改进的方式确定泡沫炉渣的高度,并且由此优化发泡炉渣成形器的进料,该方法包括以下步骤:a)确定振荡之间的函数关系(h = f(a)) 通过测量在电弧炉(1)的操作期间电极(4)或承载臂(5)和泡沫炉渣(6)的高度(h); b)操作电弧炉(1),测量电极(4)或载体臂(5)的振荡,并且基于这些测量值,发泡炉渣(6)的高度(h) 使用在步骤a)中确定的功能关系(h = f(a))来确定。
