What are the temperatures of vacuum atmosphere furnaces?

The temperature range of a vacuum atmosphere furnace is quite wide, which mainly depends on the specific model, design, and application field of the furnace. Generally speaking, the temperature of a vacuum atmosphere furnace can reach several hundred to several thousand degrees Celsius. The following is a detailed summary of the temperature range of the vacuum atmosphere furnace:
1、 Overview of temperature range
The temperature range of most vacuum atmosphere furnaces is between 200 ° C and 2000 ° C, but there are also some specially designed furnaces that can achieve higher temperatures.
The temperature range of vacuum tube atmosphere furnaces is particularly wide, generally reaching 500 ° C to 2000 ° C. Stoves of different models and application fields have different temperature ranges and can be selected according to specific needs.
2、 Example of specific temperature range
The temperature range of the high-temperature vacuum atmosphere furnace can be adjusted according to actual needs, usually up to 1000 ° C to 1800 ° C. In a vacuum atmosphere, the heating temperature can even reach above 1800 ° C.
For some special applications, such as sintering and production of high-temperature materials, a vacuum atmosphere furnace may require a furnace temperature of up to 2000 ° C.
Some vacuum atmosphere furnaces also have a commonly used temperature of 1400 ° C, and the temperature control accuracy can reach ± 1 ° C.
3、 Temperature control methods
The vacuum atmosphere furnace controls the temperature through various methods to ensure the accuracy and stability of experiments or production:
Thermocouples/Thermistors: These sensors are used to measure the temperature in the furnace and provide feedback to the temperature control system. They can come into direct contact or be placed near the material to be heated.
Optical temperature measurement: Using non-contact temperature measurement equipment such as infrared thermometers or radiation thermometers, the temperature is determined by capturing the infrared radiation on the surface of the furnace.
Programmable temperature controller: used to monitor and adjust the temperature of the furnace, ensuring temperature stability and accuracy.
Multi point temperature control: In large vacuum tube atmosphere furnaces, it may be necessary to measure and control temperature at different positions to achieve more uniform heating effects.
4、 Summary
In summary, the temperature range of vacuum atmosphere furnaces is wide and can be selected according to specific needs. Through advanced temperature control methods, vacuum atmosphere furnaces can ensure the accuracy and stability of experiments or production. When choosing a vacuum atmosphere furnace, in addition to considering the temperature range, it is also necessary to pay attention to factors such as the performance, parameters, brand reputation, and after-sales service of the furnace.
