Equipment for heating in a vacuum environment. The furnace chamber, sealed with a metallic or quartz glass enclosure, is connected to a high vacuum pump system via pipes. The vacuum degree in the furnace can reach up to 133×(10-2～10-4)Pa. The heating system inside the furnace can be directly heated by resistive heating elements (such as tungsten wires) when powered, or by high-frequency induction heating. The temperature can reach approximately 3000°C. Join us as we explore the features and capabilities of second-hand vacuum furnaces.
Vacuum hardening (tempering, annealing) is a process that involves heating and cooling materials or parts in a vacuum state according to a set of technical specifications to achieve the desired performance.
Vacuum brazing is a welding process in which a set of components is heated to a temperature above the melting point of the filler metal but below that of the base metal in a vacuum environment. This facilitates the wetting and flowing of the filler metal over the base metal to form a weld joint (the brazing temperature varies depending on the material).
Vacuum sintering is a method that involves heating metal powder products under a vacuum, allowing adjacent metal powder grains to sinter into components through adhesion and diffusion.
Vacuum Magnetizing is primarily used for magnetic treatment of metal materials.
The second-hand vacuum furnace is primarily used for ceramic firing, vacuum smelting, degassing of electrical vacuum components, annealing, brazing of metal parts, and ceramic-metal sealing. Depending on the furnace's application, the furnace chamber is equipped with different types of heating elements, such as resistors, inductive coils, electrodes, and electron guns. The furnace chamber for melting metals is fitted with crucibles, and some models also feature automatic pouring devices and mechanical loaders. The vacuum system is mainly composed of vacuum pumps, vacuum valves, and vacuum gauges. This is the introduction of the functional features of the second-hand vacuum furnace provided by the editor.
