Abstract
SE PRESENTA UN PROCESO PARA LA FUNDICION DE LOS INGREDIENTES QUE FORMAN EL VIDRIO SOLIDO EN UN HORNO REGENERATIVO O RECUPERATIVO QUE TIENE UNA ZONA DE FUNDICION CORRIENTE ARRIBA Y UNA ZONA DE AFINO CORRIENTE ABAJO QUE CONSISTE EN: A) INTRODUCIR LOS INGREDIENTES QUE FORMAN EL VIDRIO SOLIDO EN LA ZONA DE FUNDICION CORRIENTE ARRIBA; Y B) CALENTARLOS DE MODO QUE SE FORME LA INTERFACETA ENTRE ELLOS Y EL VIDRIO FUNDIDO; Y C) PROPORCIONAR UN CALOR SUFICIENTE COMO PARA MANTENER AL VIDRIO FUNDIDO EN EL ESTADO DE FUNDIDO A TRAVES DE LA ZONA DE AFINO CORRIENTE ABAJO Y SUFICIENTE TAMBIEN COMO PARA FUNDIR LOS INGREDIENTES QUE FORMAN EL VIDRIO SOLIDO EN DONDE, AL MENOS UNA PARTE DEL CALOR ES PROPORCIONADO POR AL MENOS UN QUEMADOR QUE EL COMBUSTIBLE QUE UTILIZA ES OXIGENO QUE SE ENCUENTRA EN LA CUBIERTA DEL HORNO, CUYA POSICION ES TAL QUE LA PUNTA DE SU LLAMA SE DIRIGE A LA INTERFACETA DE LOS INGREDIENTES QUE FORMAN EL VIDRIO SOLIDO Y EL VIDRIO FUNDIDO EN UN ANGULO DE 25 (GRADOS) A 90 (GRADOS) DE TAL MODOQUE AUMENTA LA VELOCIDAD DE FUNDICION Y SE EVITA SUSTANCIALMENTE QUE LOS INGREDIENTES QUE FORMAN EL VIDRIO SOLIDO SE ESCAPEN DE LA ZONA DE FUNDICION CORRIENTE ARRIBA.
