Introduce the precautions for using the vertical tube furnace
Here are some important things to note when using a vertical tube furnace:
1. Safety protection
- Operators should wear appropriate protective equipment, such as high-temperature resistant gloves, goggles, etc.
2. Equipment inspection
- Carefully check the appearance of the tube furnace before use to ensure that the furnace body is not damaged or cracked, the heating elements are normal, and the control system functions intact.
- Check the gas pipeline and valve to ensure that there are no leaks.
3. Sample preparation
- The samples to be processed should be pre-treated by drying and removing impurities in advance to prevent unexpected reactions in the furnace.
4. Sample loading specifications
- Be careful when loading the sample to avoid collision or scratching the sample with the inner wall of the furnace tube.
- Make sure that the sample is placed stably and will not fall or block the airflow during heating.
5. Atmosphere control
- If specific gases need to be introduced, the gas flow and type should be accurately set according to the experimental requirements.
- Ventilate first, then heat, stop heating at the end, and stop ventilation after cooling.
6. Temperature setting
- Set the heating temperature and heating rate strictly according to the experimental requirements and sample characteristics to avoid damage to the sample or furnace body due to excessive temperature.
7. Cooling process
- After heating, cooling should be carried out in accordance with the prescribed cooling method. Rapid cooling should not be forced to avoid damage to the furnace body and samples.
8. Power management
- Ensure that the power connection is stable to avoid sudden power outages or voltage fluctuations that affect the equipment and experiments.
9. Regular maintenance
- Regularly maintain the tube furnace, clean up the debris in the furnace, and check the performance of the heating elements and thermocouples.
10. Emergency handling
- Be familiar with the emergency stop button and emergency plan of the equipment, and take quick measures in the event of abnormal situations.
11. Training and operating qualifications
- Operators should undergo professional training, be familiar with the operating procedures and precautions of the equipment, and can use it independently only after they have the operating qualifications.
