Classification and Applications of Vacuum Furnaces

With the continuous advancement of technology, vacuum furnaces play an increasingly crucial role in various industrial fields. Depending on their design and intended applications, vacuum furnaces can be classified into several categories. This article will introduce some common classifications of vacuum furnaces and their applications in different industrial sectors.

Various types of vacuum furnaces

1. Classification by Heating Method

• Resistance Heating Vacuum Furnace: Utilizes resistance heating elements to generate heat within the material, suitable for processes such as metal heating and annealing.
• Induction Heating Vacuum Furnace: Applies the principle of induction heating, generating heat in the workpiece through an alternating electromagnetic field. It is suitable for high-frequency induction heating applications, such as melting and heat treatment.
• Radiation Heating Vacuum Furnace: Employs radiation heating by using electric heating elements to produce electromagnetic waves, suitable for applications requiring uniform surface heating.
