Abstract

EL INVENTO SE REFIERE A UN HORNO DE MANTENIMIENTO DE LA TEMPERATURA PARA PRODUCTOS METALURGICOS, MAS ESPECIALMENTE PARA BARRAS, QUE COMPRENDE UNA PISTA DE RODAMIENTO DE RODILLOS (1) QUE SE EXTIENDE A TRAVES DE UN TUNEL AISLADO TERMICAMENTE QUE INCLUYE UNA REGION PASIVA DE MERO AISLAMIENTO TERMICO Y UNA REGION DE RECALENTADO ACTIVO. CON ARREGLO AL INVENTO, SE PROPORCIONAN QUEMADORES (21) EN LA REGION ACTIVA DEL TEJADO O BOVEDA DEL TUNEL EN HILERAS SUCESIVAS TRANSVERSALES A LA PISTA DE RODADURA DEL RODILLO. ADEMAS, CON ARREGLO AL INVENTO, SE FACILITA UNA REGION ACTIVA CON UN SISTEMA DE EVACUACION DE HUMO (38,39,41,42, O 43,44). EL INVENTO CONTEMPLA IGUALMENTE UNA CONSTRUCCION PARTICULAR DE LOS RODILLOS (2) PARA LA PISTA DE RODADURA DE LOS RODILLOS.
