OPERATING METHOD FOR AN ARC FURNACE
A furnace vessel (1) of an arc furnace is loaded with metal (2) in a solid state of matter. Afterward, an energy supply device (3) of the arc furnace draws electrical energy from a supply network (4) and feeds the drawn electrical energy to electrodes (6) of the arc furnace via a furnace transformer...

| description | A furnace vessel (1) of an arc furnace is loaded with metal (2) in a solid state of matter. Afterward, an energy supply device (3) of the arc furnace draws electrical energy from a supply network (4) and feeds the drawn electrical energy to electrodes (6) of the arc furnace via a furnace transformer (5), with the result that arcs (12) form between the electrodes (6) and the metal (2) or the metal melt (13), the arcs causing the metal (2) to be melted to form the metal melt (13). Finally, the metal melt (13) is removed from the furnace vessel (1). The number of electrodes (6) is at least three. For at least two of the electrodes (6), the energy supply device (3) individually sets the operating frequency (fa, fb) of the relevant electrode (6a, 6b). The current (Ic) through the third electrode (6c) is defined by the current (Ia, Ib) through the first and the second electrodes (6a, 6b). With respect to electrodes (6) of a totality of electrodes (6) of the arc furnace, the fact of which of them is the first electrode {6a), which of them is the second electrode (6b) and which of them is the third electrode (6c) is assigned to the electrodes dynamically.
Un recipiente (1) de un horno de arco se carga con metal (2) en estado sólido de materia. A continuación, un dispositivo de alimentación (3) del horno de arco extrae energía eléctrica de una red de suministro (4) y alimenta la energía eléctrica extraída a los electrodos (6) del horno de arco a través de un transformador de horno (5), con el resultado de que se forman arcos (12) entre los electrodos (6) y el metal fundido (13). Por último, la masa fundida metálica (13) se retira del recipiente del horno (1). El número de electrodos (6) es de al menos tres. Para al menos dos de los electrodos (6), el dispositivo de alimentación (3) ajusta individualmente la frecuencia de funcionamiento (fa, fb) del electrodo correspondiente (6a, 6b). La corriente (1c) a través del tercer electrodo (6c) está definida por la corriente (1a, 1b) a través del primer y el segundo electrodos (6a, 6b). Con respecto a los electrodos (6) de una totalidad de electrodos 6) del horno de arco, el hecho de cuál de ellos es el primer electrodo (6a), cuál de ellos es el segundo electrodo (6b) y cuál de ellos es el tercer electrodo (6c) se asigna a los electrodos de forma dinámica. |
