Abstract (en)
[origin: CA2796202A1] The invention relates to a method for pre-heating annealing material (4, 5) in a hood-type annealing system having annealing bases (1, 2) that accommodate the annealing material (4, 5) under a protective hood (7) in a protective-gas atmosphere, wherein the annealing material (4) to be subjected to a heat treatment in a protective hood (7) is pre-heated by means of a gaseous heat-transfer medium, which flows around the protective hoods (7) from the outside in a circuit and absorbs heat from annealing material (5) already heat-treated in a protective hood (7) and rejects heat to annealing material (4) to be pre-heated in another protective hood (7). In order to achieve advantageous use of the thermal energy, at least one further annealing base (3) having a protective hood (7) that can be heated from the outside by means of burners (15) is used to heat-treat the annealing material (4, 5, 6), and the hot exhaust gases from the heater of said protective hood (7) are mixed with the heated heat-transfer medium for pre-heating the annealing material (4).
