Vacuum pumping function of tubular atmosphere furnace
Vacuum system configuration:
A tubular atmosphere furnace is usually equipped with a vacuum system consisting of a vacuum pump, vacuum valve, vacuum pressure gauge, etc.
There are relief valves and inlet valves installed on the vacuum pipeline for pre vacuuming or introducing protective gas.
According to experimental requirements, different vacuum pumps can be selected, such as mechanical pumps, diffusion pumps, or molecular pumps, to achieve different degrees of vacuum. For example, mechanical pumps are suitable for a vacuum range of 10 ^ -1 Pa, while diffusion pumps or molecular pumps can achieve higher vacuum levels of 10 ^ -2 Pa to 10 ^ -3 Pa.

Vacuum operation:
Before the experiment, the gas inside the furnace can be evacuated using a vacuum pump to create a vacuum environment.
According to experimental requirements, inert gases (such as nitrogen, argon) or other specific atmospheres can be introduced after vacuuming to control the atmosphere conditions inside the furnace.
The operation of vacuum pumps and vacuum valves is usually carried out through a control panel, which has a user-friendly interface for operators to set parameters and monitor the experimental process.

The role of vacuum environment:
In a vacuum environment, adsorbed gases, residual gases in pores, and reaction gas products can be effectively eliminated, reducing the pollution of harmful components (such as water, oxygen, nitrogen, etc.) in the atmosphere to the product.
For atmosphere sensitive materials such as metal materials and semiconductor materials, a vacuum environment can prevent the materials from being oxidized, decarburized, etc. at high temperatures, ensuring the purity and performance of the materials.
The vacuum environment also helps to improve the properties of materials, such as increasing their density and improving the microstructure of alloys.

Other characteristics of tubular atmosphere furnace
Temperature control system:
Tube atmosphere furnaces usually use PID controllers for temperature control, which have multi-stage program setting functions.
Temperature control instruments can be set with heating time, holding time, and cooling program to meet the temperature change requirements of different experiments.
The temperature control accuracy is high, usually up to ± 1 degree, ensuring the accuracy of experimental results.

Furnace structure:
The furnace body of a tubular atmosphere furnace usually uses high-purity alumina polycrystalline fiber insulation material to reduce energy loss.
Furnace tubes are usually made of high-purity quartz tubes or stainless steel flanges, which have good high temperature resistance and corrosion resistance.
Some tubular atmosphere furnaces also adopt a split design, which is convenient for loading, retrieving, and replacing pipes.

Scope of application:
Tube atmosphere furnaces are suitable for material processing in many fields such as ceramics, metallurgy, electronics, glass, chemical engineering, machinery, refractory materials, and new material development.
Can be used for annealing, tempering, sintering of metal materials, sintering of ceramic materials, heat treatment of electronic materials, etc.
Meet the needs of various high-temperature treatment processes, such as sintering, melting, annealing, quenching, tempering, etc., and can also be used for special processes such as CVD experiments, vacuum annealing, and atmosphere reduction.
