The temperature range of high-temperature vacuum atmosphere tube furnace is usually between 1200 ℃ and 1700 ℃, and some equipment can reach up to 2200 ℃, with a temperature control accuracy of ± 1 ℃, which can meet the needs of high-temperature experiments and industrial production. The following analysis will be conducted from the dimensions of temperature range, temperature control accuracy, temperature uniformity, and heating rate:
1. Temperature range
The temperature range of high-temperature vacuum atmosphere tube furnace is wide, usually reaching between 1200 ℃ and 1700 ℃, and some high-end equipment can even raise the highest temperature to 2200 ℃. This temperature range can meet the needs of most high-temperature experiments and industrial production, such as high-temperature calcination and sintering of metal ceramics, cracking of polymer materials, etc.
2. Temperature control accuracy
The high-temperature vacuum atmosphere tube furnace has a high-precision temperature control system, and the temperature control accuracy can usually reach ± 1 ℃. This high-precision temperature control capability enables the equipment to maintain a stable temperature environment in experiments and industrial production, ensuring the accuracy and reproducibility of experimental results.
3. Temperature uniformity
In order to ensure uniform temperature distribution inside the furnace, the high-temperature vacuum atmosphere tube furnace adopts advanced furnace design and heating element layout. The temperature distribution inside the furnace is uniform, and the temperature difference can be controlled within a very small range (such as ± 5 ℃), thereby ensuring the consistency of the treatment effect.
4. Heating rate
The heating rate of the high-temperature vacuum atmosphere tube furnace can be adjusted according to experimental requirements, usually set within the range of 0-20 ℃/min. Some devices also have a rapid heating function, which can reach the set temperature in a short period of time and improve experimental efficiency. For example, some devices can raise the temperature from room temperature to 1000 ℃ within 30 minutes.
