Abstract

PROCEDIMIENTO Y APARATO PARA IGUALAR LA TEMPERATURA A TRAVES DE LA SECCION TRANSVERSAL DE UNA MASA DE VIDRIO FUNDIDO QUE FLUYE A TRAVES DE UN HORNO DE AFINO. CONSISTE EN SUMERGIR ELECTRODOS EN EL VIDRIO FUNDIDO A LO LARGO DE LOS LADOS OPUESTOS DE SU TRAYECTO HACER PASAR CORRIENTE ELECTRICA PARA CONSEGUIR UN CALENTAMIENTO ENTRE LOS ELECTRODOS Y CONTROLAR POR SEPARADO LA MAGNITUD DE LA CORRIENTE ELECTRICA QUE PASA POR LOS ELECTRODOS. TODO ELLO SE REALIZA EN UN APARATO CON UNA ZONA DE ACONDICIONAMIENTO (11) DONDE EXISTE UN CONJUNTO DE TERMOPARES (71) Y UNA ZONA DE ALIMENTACION (13).
