Description

Double-layer sealed high-pressure circulating air annealing furnace

Technical Field

The utility model belongs to the technical field of annealing stove, especially, relate to a double-deck sealed high pressure circulation wind annealing stove.

Background

Annealing is a heat treatment process commonly used in the production of metal wire. In the annealing process, the metal wire needs to be heated to a certain temperature, then is kept at the temperature for a period of time, and then is slowly cooled. In a conventional annealing furnace, hot air is passed through a common fan to heat the metal coil from the bottom thereof. The annealing process has a drawback in that hot air can only directly heat the lower surface of the metal coil and cannot directly contact the rest of the metal coil, which causes non-uniformity of the temperature of the metal coil, may cause the annealing process not to achieve a desired effect, and the annealing quality is not stable.
