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