Do you know how a vacuum tube furnace works in a high-temperature furnace?
The vacuum tube furnace is a vacuum environment， and combined with heat treatment technology, the vacuum tube furnace can complete the sintering of products. Because of the vacuum, the products placed in the furnace do not react with air and thus change their original properties. In addition, according to different criteria, vacuum tube furnaces can be divided into different types, and the scope of application of different types of vacuum tube furnaces also differs.
The working principle of vacuum tube type experimental furnace is to use a quartz tube or corundum tube as a sealed container, the choice of stainless steel sealing flange so that the quartz tube or corundum tube meets the conditions of sealing, at the same time can be very convenient to take and put the experimental materials.
When using the vacuum tube type experimental furnace, just put the experimental material into the quartz tube or corundum tube, through the stainless steel flange to seal the quartz tube or corundum tube, through the vacuum pump or flange on the reserved air inlet, extracting the quartz tube or corundum tube gas or pass into the specific atmosphere, in the quartz tube or corundum tube heating to meet the requirements of the experiment.
Vacuum tube type experimental furnace in the atmosphere, it is recommended that the first pre-pumping vacuum, and then into the corresponding atmosphere, such as conditions allow, it is best to repeat several times so that in the experiment, high-temperature furnace tube atmosphere purity will be higher.
