Abstract

EN UN HORNO POR ARCO VOLTAICO DE IGUAL INTENSIDAD QUE DISPONE DE UN ELECTRODO DE FONDO 2 SE ELIMINAN AMPLIAMENTE MOVIMIENTOS DE BAÑO PRODUCIDOS DE FORMA ELECTROMAGNETICA Y/O QUIMICA MEDIANTE UN ELECTROMAGNETICO 9 SITUADO POR DEBAJO DEL FONDO DEL RECIPIENTE 7. DE ESTA FORMA SE CONSIGUE UNA MAYOR ESTABILIDAD DEL ELECTRODO DEL FONDO 2. EL ELECTROMAGNETICO 9 SE INTEGRA PREFERIBLEMENTE EN LA ALIMENTACION ELECTRICA DEL HORNO Y SIRVE COMO COMPUERTA DE FILTRO.
