What is a vacuum annealing furnace
Vacuum furnace is widely used in ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new materials development, special materials, building materials and other categories of consumption and experiments. In powder metallurgy, vacuum sintering is mainly used for sintering active and refractory beryllium, thorium, titanium, zirconium, tantalum, niobium, etc. Sintered hard alloy, magnetic alloy, tool steel and stainless steel; And sintering compounds that tend to react with gases such as hydrogen, nitrogen and carbon monoxide.
Vacuum furnace is also known as anaerobic annealing furnace, vacuum atmosphere sintering furnace and other objects in a certain gas into the furnace to stop sintering method. The selection of suitable atmosphere for sintering by different materials is conducive to the sintering process, improving the density level of products and achieving good performance. Vacuum atmosphere furnace commonly used in vacuum, hydrogen, oxygen, nitrogen and inert gases (such as argon) atmosphere. For example, transparent alumina ceramics can be sintered with hydrogen atmosphere, transparent ferroelectric ceramics should be sintered with oxygen atmosphere, nitride ceramics such as aluminum nitride should be sintered with nitrogen atmosphere. Sometimes for the maintenance of sintering coordination must also operate in the maintenance atmosphere. If the molybdenum wire furnace is suitable for hydrogen, the tungsten wire furnace is suitable for working under vacuum conditions.
I. application of vacuum chamber furnace
The vacuum chamber furnace for silicon carbide heating elements, the double hull structure and 40 segments program temperature control system, the phase shift trigger, thyristor control, furnace using polycrystalline alumina fiber materials, vacuum chamber furnace widely applied in the metal materials under low vacuum, resilience and maintainability atmosphere heat treatment; It can also be used for heat treatment of special data.
Main characteristics of vacuum chamber furnace
Furnace door device has a water cooling system, gas after flowmeter by the breech, and how to wash the furnace inlet and the outlet has put out the mouth, can lead to hydrogen and argon, nitrogen, oxygen, carbon monoxide and other gases, vacuum, vacuum degree can reach 5 pa, &energy-saving balance, external temperature, low temperature field, elevating temperature rate quickly, the advantages of energy saving, universities, research institutes, industrial and mining enterprises do maintenance of sintering atmosphere, atmosphere with the ideal product.
