An annealing furnace is an apparatus for performing an annealing treatment. Annealing is a heat treatment process by heating a material to a temperature and maintaining the temperature for a period of time, and then slowly cooling to change the structure and properties of the material. The annealing furnace has the main functions of removing the stress in the material, improving the hardness and toughness of the material and improving the processing performance of the material. The annealing furnace heats and cools the material by controlling the temperature and time to change the structure and the performance of the material, thereby meeting the requirements of different processes and applications.
Heating elements (such as an electric heater, a burner and the like) are usually arranged in the annealing furnace, and can transfer heat to the furnace chamber of the annealing furnace, so that materials (metal workpieces) in the furnace chamber of the annealing furnace are heated, and along with the rise of the temperature, air in the furnace chamber of the annealing furnace can be heated to form high-temperature flue gas. And volatile matters (such as grease, moisture and the like) possibly remain on the surfaces of materials (metal workpieces) in the furnace chamber of the annealing furnace, and the volatile matters can escape in the heating process to form smoke.
An annealing furnace is a closed device, and flue gas generated by combustion or heating needs to be discharged outside the furnace to prevent the rise of pressure in the furnace or the accumulation of flue gas. Through the fume exhaust port (the air outlet 120), the high-temperature fume can be smoothly exhausted from the annealing furnace. Meanwhile, the high-temperature flue gas is discharged to bring heat energy generated in the annealing furnace due to combustion or a heating process, so that the temperature in the annealing furnace is regulated.

The heating efficiency of the metal workpiece (annealing piece) in the annealing furnace can be improved by improving the temperature of the fresh air; the heat transfer efficiency in the annealing furnace is improved, so that the metal workpiece is heated more uniformly; the energy consumption of the annealing furnace is reduced, and the energy utilization efficiency is improved; improving the mechanical property and structural characteristics of the metal and enhancing the annealing effect.
