Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA REGULACION DE HORNOS DE ARCO ELECTRICO. EL DISPOSITIVO CONSTA DE UNA INSTALACION DE HORNO (18) CONSTITUIDA SUSTANCIALMENTE POR UN TRANSFORMADOR (3) CON ACCIONAMIENTO DE INTERRUPTOR ESCALONADO (23), MEDIANTE EL CUAL SE SUMINISTRA LA TENSION ENTRE LOS ELECTRODOS (19) Y EL BAÑO (20); DE UN EQUIPO DE MEDICION (10); Y DE UN PANEL DE MANDO CENTRAL (8) A TRAVES DEL CUAL SE ENTREGAN TODOS LOS VALORES NOMINALES PARA LA CORRIENTE DE LOS ELECTRODOS, LA TENSION DE LOS ELECTRODOS, LA POTENCIA DE LOS ELECTRODOS Y EL COEFICIENTE DE DESGASTE. EL PANEL DE MANDO (8) ESTA UNIDO DIRECTAMENTE CON LOS REGULADORES CORRESPONDIENTES, EN PARTICULAR CON LOS REGULADORES DE CORRIENTE (1, 2).
