Abstract

UN HORNO DE ARCO ELECTRICO MEJORADO PARA FABRICAR ACERO. SE DESCRIBE UN HORNO DE ARCO ELECTRICO PARA LA FABRICACION DE ACERO EN EL QUE SE HACE PASAR UNA CORRIENTE ELECTRICA A TRAVES DE UN ELECTRODO DE GRAFITO PARA ESTABLECER UN ARCO ELECTRICO ENTRE LA PUNTA DE DICHO ELECTRODO Y EL METAL FUNDIDO, EN DONDE EL ELECTRODO DE GRAFITO TIENE UN REVESTIMIENTO QUE IMPIDE LA OXIDACION SOBRE EL MISMO, COMPRENDIENDO DICHO REVESTIMIENTO UNA CAPA BASE SUPERYACENTE Y UNIDA A LAS SUPERFICIES DE DICHO ELECTRODO DE GRAFITO, ESTANDO CONSTITUIDA DICHA CAPA BASE POR UN MATERIAL CERAMICO REFRACTARIO CONSTITUIDO POR PARTICULAS, SINTETIZADO, POROSO, DE BAJA RESISTENCIA Y ELASTICO, Y UNA CAPA DE RECUBRIMIENTO SUPERYACENTE Y UNIDA A DICHA CAPA BASE QUE COMPRENDE UNA SUSTANCIA VITREA Y RIGIDA QUE ES PLASTICA Y CAPAZ DE FLUIR A TEMPERATURAS SUPERIORES A APROXIMADAMENTE 750JC.
