Abstract: The invention relates to a device and to a method for sensing a conveying rate at which liquid material is filled into a metallurgical target vessel (6) from a pivotable starting vessel (4). For this purpose, means for determining an amount of liquid material with which the initial vessel (4) has been filled and means for sensing an amount of the liquid material which is discharged toward the target vessel (6) or filled into the target vessel (6) by pivoting of the starting vessel (4) are provided.

Abstract: The invention relates to a method for the granulation of a metallurgical slag, wherein liquid slag (1) is atomized by blowing air (2) onto it and the slag particles (3) granulated in this way are collected. In order to ensure a high quality of the granulate and operate in the most energy-efficient manner possible, the invention provides that the atomization is done by blowing heated air jet (2) free from the addition of water onto the liquid slag (1) and the slag is supplied to a working chamber (4), wherein the granulated slag particles (3) are collected in the floor region of the working chamber (4), wherein the air (5) escaping from the working chamber (4) is either supplied to a heat exchanger (6), which preheats the air jet blown onto the liquid slag (1), or directly recirculated in order to atomize the liquid slag (1).

Abstract: The invention relates to an electric arc furnace and a method for operating same. The electric arc furnace comprises a lower vessel and a lid 120 placed on said lower vessel. The lower vessel has a tapping device for tapping molten metal. At least one electrode protrudes through the lid into the interior of the electric arc furnace, said electrode being held by an electrode holding device. A supply voltage device 150 is provided for supplying an electric direct current or alternating current to the electrode 130. The aim of the invention is to allow a continuous operation of the electric arc furnace. This is achieved in that the electrode holding device has an electrode adjusting device for adjusting the electrode dependent on the wear of the electrode and an electrode nippling device for nippling the electrode during the operation of the electric arc furnace. According to the invention, both the electrode adjusting device as well s the electrode nippling device 144 operate when the supply voltage of the electrode is switched on.
