Abstract
UN METODO DE PRECALENTAMIENTO DE TIRAS DE ACERO. EN UN TRATAMIENTO CALORIFICO CONTINUO UTILIZANDO UNA ZONA CALENTADORA QUE INCLUYE TUBOS RADIANTES QUE COMPRENDE UNA COMBINACION DE UNA PRIMERA Y UNA SEGUNDA ETAPAS DE PRECALENTAMIENTO. EN LA PRIMERA ETAPA DE PRECALENTAMIENTO, EL CALOR SENSIBLE CONTENIDO EN UN GAS RESIDUAL QUEMADO DE LA ZONA DE CALENTAMIENTO SE SOMETE A INTERCAMBIO DE CALOR CON UN GAS PARA RECUPERAR PARTE DEL CALOR SENSIBLE EN EL GAS QUE SE DIRIGE A UNA TIRA DE ACERO. EN LA SEGUNDA ETAPA DE PRECALENTAMIENTO, SE CALIENTA UN MEDIO CALENTADOR EN UN DISPOSITIVO CALENTADOR Y SE SUMINISTRA Y CIRCULA EN RODILLOS. LA TIRA DE ACERO SE ENROLLA SOBRE LOS RODILLOS PARA ENTRAR SOBRE ELLOS EN UNA ATMOSFERA NO OXIDANTE. DE ESTA MANERA, LA TIRA DE ACERO SE PRECALIENTA PROGRESIVAMENTE A TEMPERATURAS MAS ALTAS PARA CONSEGUIR EL PRECALENTAMIENTO A TEMPERATURA ELEVADA SIN CAUSAR MOVIMIENTO SERPENTINO DE LA TIRA DE ACERO, CON LO QUE SE COMPACTA LA INSTALACION CALENTADORA Y SE MEJORA EL RENDIMIENTODE LA PRODUCCION.
