Abstract

DONDE EL METODO COMPRENDE: a) SOSTENER UN DEPOSITO DE MOLDEO DE ACERO FUNDIDO SOBRE UNO O MAS SUPERFICIES DE MOLDEO DE COQUILLA; b) MOVER LA(S) SUPERFICIE(S) DE MOLDEO DE COQUILLA CON LA FINALIDAD DE PRODUCIR UNA LAMINA DE ACERO SOLIDIFICADA QUE SE SEPARE DEL DEPOSITO DE MOLDEO; c) GUIAR LA LAMINA SOLIDIFICADA SUCESIVAMENTE A TRAVES DE DOS CAMARAS, PURGADAS CON GAS INERTE PARA REDUCIR EL CONTENIDO INICIAL DE OXIGENO ENTRE 5% Y 10% ANTES DE INICIAR EL MOLDEO, A MEDIDA QUE SE ALEJA DEL DEPOSITO DE MOLDEO; d) SELLAR LOS DOS CAMARAS A FIN DE EVITAR EL INGRESO DE AIRE; y, e) INTRODUCIR AGUA EN UNA DE LAS CAMARAS, EN FORMA DE UN VAHO FINO POR MEDIO DE ROCIADORES NEBULIZADORES FINOS DIRIGIDOS SOBRE LA CARA SUPERIOR DE LA LAMINA, CON EL FIN DE ORIGINAR VAPOR DE AGUA DENTRO Y, DESDE ALLI, PRODUCIR UNA PRESION MUCHO MAYOR QUE LA ATMOSFERICA. LA LAMINA SALE DE UNA DE LAS CAMARAS A UNA TEMPERATURA ENTRE 1150°C Y 1300°C. LA LAMINA PASA DE UNA CAMARA A OTRA, POR MEDIO DE RODILLOS TOMADORES QUE REDUCEN EL GROSOR DE LA LAMINA HASTA EN UN 5%. LA LAMINA SOLIDIFICADA SE CONDUCE A UN LAMINADOR CALIENTE, UBICADO AL FINAL DE UNA DE LAS CAMARAS, EN DONDE SE ENROLLA EN CALIENTE A MEDIDA QUE SE PRODUCE. EL APARATO COMPRENDE: i) UN PAR DE RODILLOS MOLDEADORES; ii) UN MEDIO DE DESCARGA DE METAL; iii) UN MEDIO PARA ENFRIAR LOS RODILLOS; iv) UN MEDIO PARA GIRAR LOS RODILLOS; v) UN MEDIO PARA GUIAR LA LAMINA; vi) DOS CAMARAS; Y, vii) MECANISMOS ROCIADORES DE AGUA
