Abstract

Un aparato de calentamiento continua que comprende un horno de calentamiento (3) que tiene segmentos de combustión en los que las cantidades de combustión pueden ser controladas individualmente y que están dispuestas en serie, para calentar de forma continua una tira de material de una manera que se controla una velocidad de transporte para el material en forma de tira a fin de mantener una temperatura final a lograr del material en forma de tira a una temperatura diana predeterminada, y una máquina de remallado (2) que está dispuesta en serie con el horno de calentamiento (3), a través del cual pasa el material en forma de tira y que está adaptada para ajustar una longitud del material en forma de tira acumulado en el interior, y caracterizado por que el aparato de calentamiento continuo comprende un controlador (7) adaptado para controlar las cantidades de combustión en los segmentos de combustión (H1-H8), respectivamente, de acuerdo con un tiempo excedente como una capacidad de ajuste restante de la máquina de remallado en la longitud del material en forma de tira dividido por el transporte de velocidad para el material en forma de tira en el horno de calentamiento (3), en donde el controlador (7) está adaptado para controlar las cantidades de combustión en los segmentos de combustión (H1- H8), respectivamente, de modo que la temperatura interna de los segmentos de combustión (H1-H8) se mantienen a temperaturas preestablecidas predeterminadas, respectivamente, si el tiempo excedente es más largo que un tiempo preestablecido predeterminado, y para variar las cantidades de combustión en los segmentos de combustión (H1-H8), respectivamente, en un perfil predeterminado con respecto al tiempo excedente si el tiempo excedente es más corto que un tiempo preestablecido predeterminado.A continuous heating apparatus comprising a heating furnace (3) having combustion segments in which combustion quantities can be individually controlled and which are arranged in series, for continuously heating a strip of material in a manner that a conveying speed for the strip material is controlled to maintain a final target temperature of the strip material at a predetermined target temperature, and an overlocking machine (2) that is arranged in series with the oven heating apparatus (3), through which the strip-shaped material passes and which is adapted to adjust a length of the strip-shaped material accumulated therein, and characterized in that the continuous heating apparatus comprises a controller (7 ) adapted to control the combustion amounts in the combustion segments (H1-H8), respectively, in accordance with a surplus time as a setting capacity. remaining te of the overlocking machine in the length of the strip material divided by the transport speed for the strip material in the heating oven (3), where the controller (7) is adapted to control the combustion amounts in the combustion segments (H1-H8), respectively, so that the internal temperature of the combustion segments (H1-H8) are maintained at predetermined preset temperatures, respectively, if the exceeding time is longer than a predetermined preset time, and for varying the combustion amounts in the combustion segments (H1-H8), respectively, in a predetermined profile with respect to the overrun time if the overrun time is shorter than a predetermined preset time.
