Abstract
A method is described for preheating annealing material (4, 5) in a hood-type annealing system, comprising annealing bases (1, 2) which accommodate the annealing material (4, 5) under a protective cover (7) in a protective gas atmosphere, with the annealing material (4) to be subjected to a heat treatment in a protective cover (7) being preheated with the help of a gaseous heat carrier which flows in a cycle around the protective covers (7) on the outside and absorbs heat from annealing material (5) which is already heat-treated in a protective cover (7) and emits it to the annealing material (4) to be preheated in the other protective cover (7). In order to achieve advantageous utilization of the thermal energy it is proposed that for the heat treatment of the annealing material (4, 5, 6) at least one further annealing base (3) is used which comprises a protective hood (7) which is heatable from the outside by a burner (15), and that the hot exhaust gases from the heating of the protective hood (7) are admixed into the heated heat carrier for preheating the annealing material (4).
