Vacuum drying heat treatment furnaces are used to remove moisture from materials, particularly through vacuum-assisted drying during the heat treatment process. The vacuum environment enables the material to be dried more quickly and uniformly at lower temperatures. This process is typically used for drying high-value metals, alloys, and delicate components. Vacuum drying furnaces are employed to remove unwanted moisture before or after heat treatment and also help eliminate internal stresses. Drying in a vacuum environment minimizes the risk of oxidation and preserves the material's surface quality.
