  • Method for preheating annealing products in a hood-type annealing system
    Patent number: 8790115
    Abstract: A method is described for preheating annealing goods in a hood-type annealing installation, comprising two annealing bases (1, 2) which accommodate the annealing goods (3, 4) under a protective cover (7, 8), with the annealing goods (3) to be subjected to a heat treatment under a protective cover (8) being preheated with the help of a gaseous heat carrier which is guided in a cycle between two protective covers (7, 8) and absorbs heat from annealing goods (4) which are heat-treated in a protective cover (7) and emits it to the annealing goods (3) to be preheated in the other protective cover (8). In order to avoid contaminations of the heat-treated annealing goods (4) it is proposed that the heat carrier flow guided in a cycle flows around the two protective covers (7, 8) on the outside, whereas a protective gas is circulated within the protective covers (7, 8).
