vacuum annealing furnace application and working mode

Vacuum annealing furnace does not need to add any gas protection, can ensure that the product does not oxidize, does not change color, really do not need follow-up treatment, the product is directly used.


Due to the special design of the outer tank heating and the placement of the inner tank, the inner tank and the outer tank control each other in terms of electric control, so as to ensure that the internal products are evenly heated and the hardness and elasticity of the products are the same.


Water circulation system: water circulation system is installed in the whole furnace outer tank to effectively protect the sealing ring and welding aging, and effectively extend the service life of the furnace body.


 vacuum annealing furnace application scope:


Beryllium copper, stamping parts, shielding cover, stainless steel, white copper, white copper, brass, red copper, metal shrapnel, Tin Phosphorus Bronze, riveting parts, rivets, silver contacts, silver copper composite sheet, copper contacts, bimetallic sheet, silver contacts and other fields, the color of the external surface of the product heat treatment is not oxidized.

vacuum annealing furnace working mode:


The vacuum annealing furnace is made of square or round furnace structure. The furnace is installed with refractory brick and aluminum silicate fiber composite insulation, or with full fiber insulation lining structure. The workpieces are placed in the furnace, and the workpieces are heated to the required annealing process temperature by electric heating, oil or gas heating. After a period of heat preservation, Natural cooling or controlled speed cooling. Because of the variety of annealing furnace series, there are different ways of operation. The trolley type annealing furnace has an independent loading trolley, which is more convenient for loading and unloading, and can load large and heavy-duty workpieces. The well type annealing furnace is suitable for vertical loading of workpieces such as shafts, rods and pipe fittings, and is not easy to deform during annealing.


vacuum annealing furnace classification:


1. The vacuum annealing furnace can be divided into three types: electric heating, oil heating and gas heating. They are electric annealing furnace, fuel oil annealing furnace and natural gas annealing furnace.


3. Different furnace structures of vacuum annealing furnace are divided into trolley type annealing furnace, well type annealing furnace, box type annealing furnace and bell type annealing furnace.


4. The vacuum annealing furnace can also be divided into vacuum annealing furnace, controlled atmosphere annealing furnace and vacuum annealing furnace heated in natural atmosphere.
