Introduction of Vacuum Tungsten Furnace
The vacuum tungsten furnace is a high-temperature heat treatment device that utilizes tungsten filaments as heating elements, specifically designed for precise material processing in a vacuum environment. Due to its exceptionally high melting point and excellent thermal stability, tungsten can perform reliably at extreme temperatures, typically achieving operating temperatures of over 2000°C. During heating, the vacuum system maintains a low-pressure environment, effectively reducing oxidation and impurities, which enhances material purity and ensures consistent quality.
