Abstract

UN HORNO DE ARCO VOLTAICO DE CORRIENTE CONTINUA (2) PARA METALURGIA QUE TIENE DOS O MAS ELECTRODOS (10) COLOCADOS EN EL RECIPIENTE DEL HORNO (5) QUE SE INTRODUCEN EN ESTE RECIPIENTE (5). PARA EVITAR LAS DESVIACIONES DEL ARCO VOLTAICO CAUSADAS POR LA FUERZA DE LOS CAMPOS MAGNETICOS GENERADOS POR LA CORRIENTE QUE LLEGA A LOS ELECTRODOS (10), SE SITUAN LOS DISPOSITIVOS DE ALIMENTACION ELECTRICA (14, 15) PARA LOS ELECTRODOS (10) AL LADO DEL ELECTRODO AL QUE ALIMENTAN, ESTANDO COLOCADOS LOS DISPOSITIVOS DE ALIMENTACION ELECTRICA (14, 15) DE CADA ELECTRODO (10) SEPARADOS DE LOS DISPOSITIVOS DE ALIMENTACION ELECTRICA (14, 15) DE LOS OTROS ELECTRODOS (10) EN DIRECCION DE LA CIRCUNFERENCIA DEL RECIPIENTE DEL HORNO (5).
