Comparison Between Conventional Heat Treatment Furnace and Vacuum Heat Treatment Furnace

1. Working principles

Conventional heat treatment furnace typically operates in the presence of air or other gases. Oxygen and other gases in the air may react with the material surface, forming oxides or other compounds.

Vacuum heat treatment furnace operates in a vacuum environment. This prevents reactions between the material and oxygen or other gases, thereby avoiding oxidation and contamination, and maintaining the purity of the material surface.


2. Treatment effects

Conventional heat treatment furnace may result in oxidation or discoloration of material surfaces, requiring subsequent cleaning and treatment.

Vacuum heat treatment furnace enables precise heating and treatment while maintaining cleanliness and structural integrity of the material surface, thus avoiding potential oxidation issues associated with conventional furnaces.


3. Applications

Conventional heat treatment furnace is suitable for general metal heating, quenching, tempering, and similar processes commonly used in industrial manufacturing.

Vacuum heat treatment furnace is primarily used for heat treating materials such as high-temperature alloys, precision parts, and optical glasses that are sensitive to oxygen and other gases. It is widely applied in aerospace, electronics, medical equipment, and other high-tech industries.
