In order to release heat to the annealing gas , especially supplied from an energy source in the furnace chamber outside the hood -type furnace with a heat emitter positioned in the interior of the protective hood .

摘要

Annealing in a furnace for heat-treating the annealed product (102) (100), a furnace (100) includes a first furnace chamber (104) first annealing gas heating can be or can be cooled in in the (112) mono (102) and the thermal interaction with the annealing product (102) a first furnace chamber closable configured to heat treatment accommodates the (104), the first furnace chamber (104) be closed, I and a removable first protective hood (120). Furthermore, in order to exchange heat with the first annealing gas (112) within the first protective hood (120), the first furnace chamber is closed by a first protective hood (120) of (104) at least partially the first heat exchange apparatus in the interior (108) is provided. Heat exchange apparatus (108), even when the first annealing gas ventilator for driving the annealing gas (130) relatively, the furnace (100) are in which operating state the first annealing gas ventilator ( annealing gas driven are arranged so as to flow the heat exchange apparatus (100) by 130). .. .
