An atmosphere furnace is a type of furnace that operates in a controlled atmosphere. This High-Temperature Furnace is used in various industries for heat treating, sintering, and other high-temperature processes that require a specific gas atmosphere to prevent oxidation or other chemical reactions that could damage the material being processed.
What is an Atmosphere Furnace?
An atmosphere furnace operates in a controlled atmosphere, generally consisting of gases like nitrogen, hydrogen, argon, etc. The furnace maintains a specific atmosphere to prevent oxidation or other chemical reactions that could damage the processed material.
This type of furnace is used for heat treating, sintering, and other high-
temperature processes in the aerospace, automotive, electronics, and metallurgy industries. They come in various sizes, from small laboratory models to large industrial models capable of handling large volumes of material.
History of Atmosphere Furnaces
Atmosphere furnace has existed for a long time, the ancient furnaces were used with wood or coal as the fuel source. However, it wasn’t until the 20th century that the technology advanced to the point where atmosphere furnaces could be used in industrial applications.
In the 1930s, protective atmospheres became more widespread in heat treatment, and atmosphere furnaces began to be used in the automotive industry. By the 1950s, atmosphere furnaces were being used in the aerospace industry, and the technology continued to advance with the introduction of computer controls in the 1970s and 1980s.
How Does Atmosphere Furnace Work?
These High-Temperature furnaces operate by creating a controlled atmosphere within the furnace to prevent oxidation or other chemical reactions that could damage the material being processed. The specific atmosphere created depends on the material being processed and the particular application’s requirements.
Depending on the specific application and requirements, atmosphere furnaces use various heating methods, including electric resistance heating, gas-fired heating, or induction heating.
Gases such as nitrogen, hydrogen, argon, or a combination of these gases are introduced into the furnace to create a controlled atmosphere. Depending on the application, the gases are carefully controlled to create the desired atmosphere, which can range from reducing to neutral to oxidizing.
The furnace is equipped with sensors and control systems that monitor and regulate the atmosphere and temperature within the furnace. These systems ensure that the furnace operates at the desired temperature and that the atmosphere is maintained at the appropriate level to prevent oxidation or other chemical reactions that could damage the processed material.
Industries that Benefit from Atmosphere Furnaces
Atmosphere furnaces are utilized in many different industries such as, electronics, and metallurgy. Here are some examples of how these industries benefit from atmosphere furnaces:
