Abstract
MODIFICACIONES EN EL PROCEDIMIENTO PARA MANTENER O ELEVAR LA TEMPERATURA DE UNA MASA METALICA FUNDIDA. LA ENERGIA SE APORTA A TRAVES DE QUEMADORES DE PLASMA CON ARCO ELECTRICO ARRASTRADO, ACCIONADOS CON CORRIENTE ALTERNA, REFRIGERADOS POR AGUA Y QUE TRABAJAN CON GAS INERTE RESPECTO A LA MASA METALICA FUNDIDA; LAS MARCHAS DE FOCO DE LOS ARCOS ELECTRICOS GENERADOS POR LOS QUEMADORES DE PLASMA INDIVIDUALES SOBREEL NIVEL DEL BAÑO DE LA MASA METALICA FUNDIDA TIENEN UNA DISTANCIAS DE SUS CENTROS AL EJE CENTRAL DEL RECIPIENTE DE ALOJAMIENTO QUE NO SOBREPASA 3/10 DEL RADO DE LA PARED INTERNA DEL RECIPIENTE DE ALOJAMIENTO A LA ALTURA DEL PERTINENTE NIVEL DEL BAÑO; LOS QUEMADORES DE PLASMA SE HACEN FUNCIONAR CON ARGON. SE UTILIZA EN METALURGIA.
