Vacuum tungsten filament sintering furnace it is a kind of ultra high temperature and high vacuum furnace for scientific research and industrial production. Suitable for high purity ceramic sintered transparent ceramic, tungsten electrode for sintering and degassing under high vacuum, vacuum sintering can also be applied to tungsten and molybdenum products. Mainly used for melting and sintering of high melting point metals, alloys, ceramics and other materials, can also be used on some metal light, degassing treatment, or for metal, ceramics etc. to determine its physical and chemical properties used in high temperature vacuum condition. Widely used in inorganic materials (such as ceramic seals, zirconia, alumina, Zinc Oxide two, etc.) and metal materials (such as hard alloy sintered in vacuum or protective atmosphere in preparation, can also be used to clean the required material for the heat treatment of sintering environment. At the same time for colleges and scientific research units in mass production and use.
Brief introduction of structure:
1. The furnace is a vertical vacuum furnace. It consists of a furnace cover, a furnace body, a furnace bottom and a vacuum unit. The inner layer of the furnace shell is stainless steel, the outer layer is carbon steel, and the two layer is cooled by circulating water. Furnace shell is provided with a pumping port, observation hole, thermocouple hole, protective atmosphere, import and export, export explosion. The heating element is heated by tungsten wire, and there is a heat shield device composed of multilayer tungsten sheet, molybdenum piece and stainless steel around the heating body. The bottom is composed of inner and outer plate welded, intermediate water. It can be lifted up and down, convenient for loading and unloading.
2, the heating body adopts three-phase cage type: tungsten mesh structure, heat stable and uniform, so that the temperature in the furnace of good uniformity, high production efficiency, strong durability, novel structure and long service life, small deformation and special energy saving etc.. The sintering sample is more beautiful and uniform
Fletcher. The tungsten wire mesh heating body in the vacuum tungsten filament furnace adopts the advanced manufacturing technology abroad, which can greatly reduce the energy consumption. The insulation layer design know-how, temperature uniformity, small deformation, long service life.
3, the heat shield: professional manufacture of multilayer metal plate processing equipment improved technology, the heat shield to be fixed, not easy to deformation, is helpful to improve the insulation performance and uniformity, but also effectively prevent heat radiation conduction, more conducive to the vacuum and cleanliness requirements have very high environment. At the same time, the high vacuum tungsten filament sintering furnace has been successfully accepted, accepted and affirmed by users.
