Abstract (en)
[origin: WO2011072883A1] The invention relates to equipment and a method for preheating a continuously moving steel strip, in particular before feeding same into a continuous annealing or hot-dip galvanizing furnace. The preheating equipment involves the continuous movement of the steel strip in a preheating chamber including a preheating circuit consisting of at least one preheating tube, the inner surface of which is in contact with externally-recovered burnt gases (e.g. from the furnace). A portion of the outer surface of the preheating tube is arranged directly opposite a surface of the strip in order to provide a first preheating mode by irradiating heat onto the strip and the walls of the chamber, and a second preheating mode, mainly by means of convection, of a gas constituting a controlled atmosphere in the preheating chamber.
