When choosing a tubular sintering furnace, the following key points should be noted to ensure that the selected equipment can meet the actual needs of experiments or production:

1. Clear usage requirements
Experimental or production objectives: Clarify the specific experimental or production activities that require a tube sintering furnace, such as material sintering, chemical reactions under atmosphere protection, etc.
Temperature range: Determine the required temperature range based on the requirements of the experiment or production material. The temperature range of a tubular sintering furnace usually ranges from several hundred degrees Celsius to several thousand degrees Celsius. For example, for high-temperature ceramic sintering, it may be necessary to choose a tubular furnace that can reach 1800 ℃ or above; For general metal heat treatment, a tube furnace at around 1200 ℃ may be sufficient.
Atmosphere control: Consider the strictness of the process on the atmosphere environment. If specific atmospheres (such as inert gases, reducing gases, or oxidizing atmospheres) are required for experiments or production, it should be ensured that the selected furnace has corresponding atmosphere control functions. If semiconductor material preparation is to be carried out, ultra-high vacuum (<10 ^ -3 Pa) or above may be required; However, for ordinary material processing, moderate vacuum (10 ^ -3~10 ^ -1 Pa) may be sufficient.

2. Furnace and heating elements
Furnace size: Determine the diameter and length of the furnace based on the size and quantity of the samples. If larger samples are frequently processed or multiple samples are processed simultaneously, a larger furnace space is required.
Heating element: The heating element is one of the core components of the tube sintering furnace, and its quality directly affects the heating efficiency and stability of the furnace. Common heating elements include resistance wires, silicon carbide rods, silicon molybdenum rods, etc. Resistance wire has low cost but is relatively suitable for lower temperatures; Silicon carbon rods can withstand higher temperatures; Molybdenum wire is suitable for special high temperature and atmospheric conditions.

3. Control system and degree of automation
Temperature control system: The accuracy and stability of the temperature control system are important for the reproducibility of experimental or production results. High precision temperature control systems typically have functions such as PID regulation and multi-stage program control, which can meet complex heating, constant temperature, and cooling requirements.
Automation level: If frequent operation of the same process is required, choosing a tubular sintering furnace with automation control function can improve work efficiency and accuracy. Furnaces with high levels of automation typically provide more suitable temperature control and more convenient operation.

4. Safety and stability
Safety protection: Ensure that the tubular sintering furnace has complete safety protection functions, such as over temperature protection, vacuum monitoring, pressure protection, overload protection, leakage protection, etc., to prevent accidents from occurring.
Stability: Reasonable furnace design (such as furnace height) can ensure stable operation of equipment, while also facilitating operation and maintenance.

5. Other considerations
Brand and after-sales: Brands are usually more guaranteed in terms of quality and performance. Good after-sales service can provide timely technical support and maintenance in case of equipment problems.
Budget and cost-effectiveness: Choose the appropriate model and configuration based on the budget. Evaluate the cost-effectiveness of different products within the budget range, taking into account factors such as consumables costs, energy consumption, and after-sales service during long-term use.
Extreme vacuum degree and leakage rate: This is related to the sealing of the furnace and the relationship between the vacuum chamber and the heating rate.
Vacuuming time: Whether the time to reach the vacuum degree is too long is also a consideration when purchasing equipment.
Communication interface and data management: Equipped with communication interface and data management software, it can record historical data and temperature rise curves paperless, correct temperature deviation errors, and achieve remote fault diagnosis and analysis functions.
