Abstract (en)
[origin: FR2853959A1] Control of the homogeneity of the temperature of steel products (2) in a reheat furnace (1) equipped with lateral burners is carried out by making all or none of the lateral burners function and by regulating the functioning time and stoppage of each burner to obtain the desired temperature. One chooses as the lateral burners from burners with a spread flame (B1-B4), make these burners function at a regime close to the maximum regime or at the maximum regime and the order of ignition of the burners is chosen to favour the stirring and the circulation of the fume in order to reduce the hot point of the flame and to obtain an improved homogeneity of temperature in the walls of the furnace and the products. An independent claim is also included for a furnace for reheating steel products equipped with lateral burners using this method of control.
