Abstract

Los productos (1) pasan a partir de un extremo de carga (2) hacia un extremo de descarga (3); en el lado del extremo de descarga, el horno exhibe una zonade calentamiento (4) equipado con quemadores de aire/combustible (41), posiblemente dopado con oxígeno, y, en el extremo de carga, exhibe una zonade recuperacion de gases de combustion o zona de drenaje (5) en la cual son eliminados los gases de combustion. Por lo menos un cuerpo de combustibleen estado gaseoso es incorporado dentro de los gases de combustion y el oxígeno es introducido en direccion ascendente posiblemente de aquel quemador deaire/gases de combustion (41) el cual está situado en la parte más alejada en sentido ascendente cuando se refiere a la direccion de la trayectoria delos productos (1) de tal manera como para quemar el cuerpo de combustible gaseoso y de este modo elevar la temperatura en la zona de recuperacion (5).Posibilita el uso de producto de fabricacion de acero de caldeo antes de la laminacion.
