Abstract

EN UN PROCEDIMIENTO DE ESTE TIPO SE HA PREVISTO LA ADICION DE CARBONO DE TAL MODO, QUE SE REALIZA TANTO AL MENOS UNA ENVOLTURA PARCIAL DEL ARCO ELECTRICO COMO TAMBIEN SE EVITA UNA AFLUENCIA SOBREDOSIFICADA DE CARBONO. PARA EL CONTROL DE LA CUOTA DE ADICION EN EL CARBONO SE REALIZA UN REGISTRO AUTOMATICO DE UNA EMISION DE RUIDO DEL HORNO DE ARCO ELECTRICO. LA AMPLITUD DEL RUIDO, AL MENOS EN UNA PARTE DE UN ESPECTRO DE FRECUENCIA, SE VALORA DE FORMA SELECTIVA DE FRECUENCIA. CUANDO SE SOBREPASA UN NIVEL DE RUIDO PREVIAMENTE DADO SE ELEVA LA CUOTA DE ADICION Y CUANDO NO SE SOBREPASA UN NIVEL DE RUIDO PREVIAMENTE DADO SE REDUCE LA CUOTA DE ADICION.
