Working Principle Of Vacuum Annealing Furnace

1.The Well-type annealing furnace extracts the air from the furnace through a vacuum pump system to create a low-oxygen, low-impurity vacuum environment, thereby preventing the metal from oxidizing or decarburizing during the heating process.

2.After the heating system is started, heating elements such as resistance wires or silicon carbide rods gradually heat the workpiece to the set temperature.

3.At high temperatures, metal grains rearrange or recrystallize, the internal stress of the material is released, and the toughness and ductility are significantly improved.

4.The temperature control system precisely adjusts the temperature inside the furnace to maintain a uniform temperature field, ensuring consistent heating of the entire batch of workpieces.

5.After annealing, the workpiece is cooled at a controlled rate through natural cooling or inert gas circulation cooling to avoid deformation caused by sudden cooling.
