Precautions for Selection of Vacuum Atmosphere Vertical Tube Furnace

As a commonly used heat treatment equipment in university laboratories and industrial and mining enterprise laboratories, the vacuum atmosphere vertical tube furnace achieves high-temperature treatment of samples without oxidation, reduction or specific atmosphere through the vacuum or controllable atmosphere environment inside the vertical furnace tube, combined with the vertical heating structure, avoiding the problem of uneven material deposition caused by gravity in the horizontal tube furnace. It can solve the problems of large footprint and uneven heat treatment in traditional tube furnaces. In the selection process of vacuum atmosphere vertical tube furnace, multiple factors need to be comprehensively considered to ensure that the selected equipment can meet the needs of experiments or production. Let’s take a detailed look at the precautions when choosing!

1. Clear usage requirements
Temperature range: Select a tube furnace with the corresponding upper temperature limit based on the highest temperature required for the experiment or production. For example, if a high temperature of 1600 ℃ is required, equipment with a maximum temperature not lower than this value should be selected.
Atmosphere requirements: Determine the required atmosphere type (such as vacuum, inert gas, reducing gas, etc.) and ensure that the selected tube furnace can provide or maintain that atmosphere.
Heating rate and temperature control accuracy: According to the process requirements, select a tube furnace with appropriate heating rate and temperature control accuracy to ensure the stability and repeatability of experiments or production.

2. Pay attention to device performance and configuration
Furnace structure and material: Vertical tube furnaces usually have the advantages of compact structure and small footprint. The material of the furnace body should have good high temperature resistance and corrosion resistance to extend the service life of the equipment.
Heating element: The heating element is one of the core components of the tube furnace, and its material and performance directly affect the uniformity and stability of the furnace temperature. Common heating elements include resistance wires, silicon molybdenum rods, etc., which should be selected according to actual needs.
Temperature control system: A good temperature control system can achieve multi-stage program heating, constant temperature control and other functions, improving the automation and accuracy of experiments or production.
Atmosphere control system: If experiments or production need to be conducted in a specific atmosphere, a tubular furnace equipped with an atmosphere control system should be selected. The system should be able to accurately control parameters such as flow rate, pressure, and purity of the atmosphere.
Vacuum system: For experiments or production that require a vacuum environment, a tube furnace equipped with a vacuum system should be selected. The performance of the vacuum system (such as maximum vacuum degree, pumping rate, etc.) should meet actual needs.

3. Consider safety and convenience
Safety protection measures: Tube furnaces should be equipped with safety protection measures such as overheating protection and leakage protection to ensure the safety of operators and equipment.
Convenience of operation: The operating interface of the device should be concise, clear, and easy to learn. At the same time, consideration should be given to the convenience of equipment maintenance, such as replacement of furnace tubes and repair of heating elements.

4. Evaluate cost-effectiveness and after-sales service
Cost effectiveness: On the premise of meeting usage needs, factors such as equipment price, performance, and service life should be comprehensively considered to choose products with high cost-effectiveness.
After sales service: Choose suppliers with good after-sales service to ensure timely and effective solutions when encountering problems during use.
