Zusammenfassung:The invention relates to a method and a plant for producing ingots that have large cross-sections of different shapes and are more than 5 meters long, said method involving casting an ingot in a short, water-cooled ingot mold (4) and withdrawing the solidifying ingot (6) until the desired ingot length has been reached, whereupon the metal pool is heated using an electroslag remelting process with the help of consumable electrodes (18), or fresh molten metal is poured from a heated intermediate vessel (3) or a heatable cover (22), and the solidifying structure is influenced by using electromagnetic agitators (1, 11, 13) during the casting operation and upon completion of the casting operation until the ingot has completely solidified. Se describe un método y planta para producir lingotes elaboradores de metales, particularmente de acero que tienen áreas en sección transversal de al menos 0.10 m2, de manera preferente de una forma ronda o también cuadrada o rectangular, a través de la fundición de una masa fundida de metal o acero ya sea directamente del cucharón de fundición usando un recipiente intermedio forrado a prueba de fuego de una manera conocida por sí misma en una lingotera corta enfriada con agua abierta hacia abajo y el retiro del lingote en solidificación de la misma por medio de una herramienta de retiro que se puede mover hacia abajo.
