What are the Types of Annealing Furnaces?

Annealing Furnaces

The continuous annealing furnaces unit integrates the cleaning, annealing, leveling, finishing, and other processes of cold-rolled strip steel. Whether the annealing temperature reaches the specified temperature, the stainless steel tube in the annealing area should be in the incandescent state, according to the process requirements. The bright annealing furnace should be closed, and the sealing ring in this place is particularly easy to wear.

Among them, softening and sagging did not appear. The continuous annealing furnace manufacturer is an important part of the continuous annealing unit.

Generally, pure hydrogen is used as the annealing atmosphere, and the purity of the atmosphere is 99. The continuous annealing furnace can be divided into preheating section, heating section, soaking section, slow cooling section, and fast Furnace sections such as cold section, aging section, and final cooling section.

If the other part of the atmosphere is an inert gas when the strip is driven by the furnace roller to run in various areas of the furnace, it should not contain too much oxygen and water vapor.

Annealing furnace

The tightness of the furnace body often causes drifting and deformation. It is isolated from the outside air, which seriously affects the stability of production; tunnel furnace manufacturers only have one exhaust port open (used to ignite the exhausted hydrogen), and the inspection method can be wiped with soapy water on the joints of the annealing furnace.

Among them, the place where gas is easy to escape is the place where the annealing furnace enters the tube and the place where the tube exits. Compared with the traditional bell furnace annealing process, it needs to be checked and replaced frequently. Bright annealing furnaces generally adopt solid solution heat treatment, that is, people Usually called “annealing”. It has the advantages of a short production cycle, compact layout, convenient production management, high labor productivity, and excellent product quality.

The annealing atmosphere is above 99%, and the temperature range is 1040~1120°C (Japanese standard). The purity of the oven can also be lower, which can be observed through the observation hole of the annealing furnace, and hydrogen is used as the protective gas. See if you are out of breath.
