A box-type atmosphere furnace is a type of experimental furnace, specifically a box-type atmosphere protection experimental furnace, manufactured based on the basic structure of a muffle furnace.
High-Temperature Box-Type Atmosphere Furnace The differences between a box-type atmosphere furnace and a box furnace (muffle furnace) are as follows:
1. Handwheel: A handwheel is clearly visible on the furnace door of a box-type atmosphere furnace. This allows the furnace door to be tightly closed during heat treatment, preventing gas leakage.
2. Inlet and Outlet: Box-type atmosphere furnaces have inlet and outlet ports, allowing the passage of protective gas. Box furnaces, on the other hand, do not have inlet and outlet ports and cannot allow the passage of protective gas.
3. Sealing: The furnace door of a box furnace is sealed with asbestos rope, which is not a complete seal. When gas is introduced, a small amount of gas may leak out from the door gaps. Box-type atmosphere furnaces have better sealing performance; the furnace door has a high-temperature resistant sealing gasket, ensuring no leakage when gas is introduced.
4. Vacuum: Box-type atmosphere furnaces can create a partial vacuum, making them a good choice for heat-treated materials requiring only a small amount of vacuum. However, box furnaces cannot create a true vacuum.
The furnace chamber of a box-type atmosphere furnace is generally square, and the dimensions can be customized. The door opens at the front and pulls outwards. There is also a door stop inside the door for better insulation. This is a commonly used high-temperature furnace, suitable for most laboratories.
Various Atmosphere Furnaces: Box-type atmosphere furnaces are mainly used in laboratories of various universities and colleges, and industrial and mining enterprises for chemical analysis, physical determination, sintering and melting of metals and ceramics, heating, roasting, drying, and heat treatment of small steel parts, as well as heat treatment processes under vacuum or atmospheric conditions for electronic components, new materials, and powder materials; and pre-firing, sintering, and brazing processes for electronic ceramic products in metallurgy, machinery, light industry, commodity inspection, higher education institutions and research departments, and industrial and mining enterprises.
