Principle
Vacuum molybdenum wire sintering furnace adopts a vertical or bedroom structure, suitable for withdrawal, brazing, sintering, and degassing of metal materials under high vacuum and high temperature conditions. It is also suitable for dehydroxylation treatment of quartz materials. The furnace body is made of stainless steel or carbon steel, and the heating element is molybdenum wire. Under the protection of H2 gas, it can perform high-temperature sintering of tungsten and molybdenum products. The equipment consists of a furnace cover (door), bottom (head), furnace body, and electric control system. It is mainly used for sintering, annealing, and welding of special high-temperature materials.
Advantages
-
Vacuum environment reduces contamination: Vacuum sintering eliminates the presence of harmful substances like water, oxygen, nitrogen, and other impurities that can contaminate materials. This prevents adverse reactions such as decarburization, carburization, reduction, oxidation, and nitriding.
-
High vacuum pressure: The vacuum pressure can reach 1.3*10^-1 Pascal, which corresponds to 99.99987% argon purity. This ultra-high vacuum environment ensures minimal contamination and optimal sintering conditions.
-
Suitable for various materials: Vacuum molybdenum wire sintering furnaces can be used for a wide range of metal materials, including molybdenum, tungsten, and quartz. This versatility makes them ideal for various applications in industries such as electronics, aerospace, and metallurgy.
-
Precise temperature control: The furnace's advanced temperature control system allows for precise adjustment and maintenance of sintering temperatures, ensuring consistent and high-quality results.
-
Efficient and energy-saving: The vacuum environment and molybdenum wire heating elements contribute to efficient energy utilization, reducing operating costs and environmental impact.
