Can a tube furnace be vacuumed?

During normal use, a tube furnace usually involves inserting materials, plugging the furnace plug, and then starting to heat and process the materials. Can a tube furnace be vacuumed during use?

In fact, the tube furnace can be evacuated during use, and it can also pass through the atmosphere. A tube furnace is a high-temperature furnace with advantages such as simple and reliable sealing, clean sintering environment, and low pollution. It mainly consists of furnace body, furnace tube, stainless steel flange, vacuum pump, intake device, etc. The material of furnace tube is generally quartz furnace tube, corundum furnace tube, stainless steel furnace tube, etc.

When using a tube furnace for vacuum operation, attention should be paid to the operation sequence and details to ensure the efficiency of equipment use and experimental results. For example, after vacuuming, the vacuum valve should be closed first, and then the vacuum pump should be turned off to prevent air from flowing back into the furnace tube. In addition, the tube furnace can also be filled with inert gases such as nitrogen and argon to reduce oxygen concentration and prevent redox phenomena in the experimental materials.

The tube furnace has the following characteristics when vacuuming:
① Anaerobic environment: By vacuuming, oxygen and other gases in the furnace chamber can be removed, creating an anaerobic or low oxygen environment. This is crucial for heat treatment of some oxygen sensitive materials, as it can effectively prevent material oxidation, sintering, or surface changes.
② Avoiding atmosphere pollution: Vacuum tube furnaces can prevent the atmosphere inside the furnace from contaminating materials, especially for some processes that require strict atmosphere, such as semiconductor manufacturing or precision component preparation.
③ Improving heat treatment quality: Vacuum tube furnace can improve heat treatment quality, improve material properties, and reduce adverse effects during the heat treatment process by conducting heat treatment in a vacuum environment.
④ Flexibility: Vacuum tube furnaces can be suitable for various heat treatment processes, including annealing, quenching, sintering, etc., to meet the needs of different materials and processes.
⑤ Energy conservation and environmental protection: Vacuum tube furnaces can reduce energy consumption, improve energy utilization efficiency, reduce emissions during heat treatment, and meet the requirements of energy conservation and environmental protection.
