<p>The invention is characterised in that a cold rolled strip (3) of aluminium is continuously transported along a transport path where a ramp of Direct Flame Impingement (DFI) burners (1) are located, for heating the strip, in that said ramp (1) is located perpendicular, or substantially perpendicular, to the direction of movement of the strip (3), in that the DFI burners (1) are mutually located such that the whole width of the strip (3) is heated to the same, or substantially the same, temperature, in that the velocity of the strip (3) passing the said ramp and the heating power of said burners (1) are adapted to heat treat the strip (3) such that annealing of the strip is carried out and in that the heat treated strip is wound to a coil (5).</p> |
