- the shielding gas may be, for example, neutral inert gas such as nitrogen and / or a reducing gas such as hydrogen or a carbon-containing gas or a mixture of gases.
- An important heat treatment process is the annealing for recrystallizing cold-rolled sheet, in particular fine and very fine sheet in the form of coils under protective gas in Bebelglühanlagen.
- a hood furnace usually has an incandescent base, which forms a furnace chamber with a protective hood. Depending on the requirements, a heating hood or cooling hood is placed over the protective cover during the heat treatment.
- a bell annealer usually consists of several glow sockets.
- the batch to be annealed is placed on the glow base and closed gas-tight with the protective cover.

- the cooling hood has air cooling, wherein a cooling air flow is generated in the intermediate space.
- the heating hood may have an electric heater or at least one fuel-powered burner.
- the annealing process takes place under protective gas in the form of hydrogen.
- the annealing process or an annealing cycle during recrystallization annealing is divided into at least two phases, specifically into at least one heating phase and one cooling phase.
- a heating hood is located on the glow base above the protective hood and heats the charge or the material to be annealed to the appropriate annealing temperature.
- the heating hood is pulled and placed a cooling hood on the glow base.
- the air cooling of the cooling hood initially causes a slow cooling of the batch or the annealing (slow cooling phase). This phase can take several hours, for example 4 to 6 hours.
- a rapid cooling device with an external fast cooler in the form of, for example, a water heat exchanger can be connected.
- a water heat exchanger instead of water and thermal oil or other suitable heat transfer fluid can be used.
- Fast cooling devices known from practice have a protective gas line with a fan, a water heat exchanger and the customary associated regulating and measuring devices.

- the cold inert gas atmosphere is conducted back into the furnace chamber in a closed circuit, where the protective gas atmosphere is circulated around the batch with the aid of a cylinder-internal gas circulation device and the charge heat dissipates to cool the charge.
- the batch is rapidly cooled during the rapid cooling phase by means of the rapid cooler.
- the rapid cooling phase lasts until a desired final temperature of the batch is reached. Thereafter, this cooling phase is terminated, the cooling hood pulled and the batch packaged.
- the glow socket is ready for the next glow of a new batch.
