Abstract

METODO PARA HACER FUNCIONAR UN HORNO DE ARCO ELECTRICO. CONSISTE EN ENCONTRAR PREVIAMENTE UNA CORRIENTE ELECTRICA I QUE SATISFAGA LA SIGUIENTE ECUACION: DPI/(PI-PL-QL)/DI F 0, EN LA QUE PI ES LA POTENCIA SECUNDARIA GENERADA EN EL TRANSFORMADOR DEL HORNO PL ES LA PERDIDA OHMICA TOTAL DEL DEVANADO SECUNDARIO DEL TRANSFORMADOR Y DE UN CIRCUITO ELECTRICO QUE CONECTA EL DEVANADO SECUNDARIO CON EL ELECTRODO DE ARCO, QL ES LA PERDIDA CALORIFICA DEL HORNO, E I ES LA CORRIENTE ELECTRICA QUE CIRCULA DESDE EL DEVANADO SECUNDARIO DEL TRANSFORMADOR HACIA EL TRANSFORMADOR; Y EN SUMINISTRAR A DICHO ELECTRODO DE ARCO LA CORRIENTE ELECTRICA, PREVIAMENTE CALCULADA, PROCEDENTE DEL DEVANADO SECUNDARIO DEL TRANSFORMADOR, AL OBJETO DE EXTENDER EL ARCO DESDE EL ELECTRODO DE ARCO Y FUNDIR LA MATERIA PRIMA CONTENIDA EN EL HORNO ELECTRICO. DE APLICACION EN HORNOS ELECTRICOS EN LOS QUE SE FUNDEN DIVERSAS MATERIAS PRIMAS.
