Vacuum atmosphere sintering furnace

Product Introduction:
Vacuum atmosphere furnace, also known as anaerobic annealing furnaceVacuum atmosphere sintering furnaceThe method of sintering an object in a furnace filled with a constant gas. Choosing the appropriate atmosphere for sintering different materials can help improve the sintering process, increase the degree of densification of the product, and obtain products with good performance. Vacuum atmosphere furnaces commonly use various atmospheres such as vacuum, hydrogen, oxygen, nitrogen, and inert gases (such as argon). For example, transparent alumina ceramics can be sintered under a hydrogen atmosphere, transparent ferroelectric ceramics should be sintered under an oxygen atmosphere, and nitride ceramics such as aluminum nitride should be sintered under a nitrogen atmosphere. Sometimes, in order to protect the sintering process, it is also necessary to operate in a protective atmosphere. Molybdenum wire furnaces are suitable for hydrogen supply, while tungsten wire furnaces should operate under vacuum conditions.
　　Purpose of Atmosphere Furnace:
The vacuum atmosphere furnace is specially manufactured for different process experiments, suitable for sintering electronic ceramics and high-temperature structural ceramics, precision annealing and microcrystallization of glass, precision annealing of crystals, preparation of ceramic glazes, powder metallurgy, sintering of nanomaterials, quenching of metal parts, and heat treatment required for rapid heating processes. It is an ideal experimental and production equipment for scientific research institutions, universities, and industrial and mining enterprises.
　　Vacuum atmosphere sintering furnacePrinciple:
Vacuum atmosphere furnace is a new type of heat treatment technology that combines vacuum technology and heat treatment technology. The vacuum environment in which vacuum heat treatment is carried out refers to an atmosphere environment below atmospheric pressure, including low vacuum, medium vacuum, high vacuum, and ultra-high vacuum. Vacuum heat treatment actually belongs to atmosphere controlled heat treatment. Vacuum heat treatment refers to the partial and partial heat treatment process carried out in a vacuum state. Vacuum heat treatment can achieve almost all the heat treatment processes that can be involved in conventional heat treatment, but the quality of heat treatment is greatly improved. Compared with conventional heat treatment, vacuum heat treatment can achieve non oxidation, non decarburization, and non carburization, remove phosphorus chips from the surface of the workpiece, and have functions such as degreasing and degassing, thus achieving the result of surface brightness purification.
　　Structure of vacuum atmosphere furnace:
Electrical part: The electrical part adopts an integrated structure with the atmosphere furnace body, and the entire electrical components are installed on the bottom side of the furnace body, with a compact structure and small space occupation. The temperature controller is installed on the side panel of the furnace body for intuitive observation and easy adjustment. The temperature controller has PID adjustment function, which can automatically track and set the PID value. The measurement division password can be set arbitrarily, and it also has compensation function, which can make the furnace temperature consistent with the displayed value.
2、 Furnace body: The furnace is built with mullite lightweight bricks, and the upper and lower parts of the furnace are covered with silicon carbide roof panels. The temperature inside the furnace is conducted by the heating element through the silicon carbide roof panels during the heating process (dark fire heating), resulting in a more uniform temperature. Sealing of furnace shell. To improve the service life of the sealing gasket of the atmosphere furnace, a circulating water cooling jacket is installed at the furnace door to reduce the temperature at the sealing area. The inlet is located at the bottom of the furnace, and after preheating in the heating chamber, it enters the furnace in multiple places. The exhaust is discharged through the rear of the furnace top. Ensure a uniform atmosphere inside the furnace and reduce the temperature difference inside the furnace. That is to say, whether it is the electrical part or the furnace body part, their structural performance is mutually reinforcing, has uniformity, and is also the basic guarantee for realizing the function of the box type atmosphere furnace!
