What should be noted during the use of an atmosphere tube furnace?

In addition to the precautions mentioned earlier, special attention should be paid to the following aspects during the use of an atmosphere tube furnace:
1. Atmosphere control
Precise control: One of the core functions of an atmosphere tube furnace is the ability to precisely control the atmosphere environment inside the furnace. When in use, the composition and concentration of the atmosphere must be strictly adjusted according to experimental or production requirements to ensure the accuracy of experimental results or the stability of the production process.
Regular inspection: Regularly check the working status of the atmosphere control system, including the accuracy and reliability of components such as gas flow meters, pressure gauges, valves, etc., to prevent atmosphere control errors caused by equipment failures.
2. Temperature control
Stable and uniform: Ensure that the temperature distribution inside the furnace is uniform and stable, avoiding local overheating or undercooling. This can be achieved through reasonable arrangement of heating elements, optimization of furnace structure, and adoption of advanced temperature control algorithms.
Real time monitoring: Use a temperature monitoring system to monitor the temperature inside the furnace in real time, and adjust the heating power or take other measures as needed to maintain temperature stability.
3. Sample processing
Sample selection: Ensure that the sample meets the requirements for the use of the furnace tube, and avoid using flammable, explosive, volatile, or corrosive samples to prevent damage to the furnace tube or safety accidents.
Sample placement: Place the sample in a suitable position inside the furnace tube to ensure uniform heating of the sample. Meanwhile, it is important to avoid direct contact between the sample and the furnace tube to prevent unnecessary chemical reactions or affect the heating effect.
4. Security protection
Fire and explosion prevention: Atmosphere tube furnaces may generate high temperatures and flammable and explosive gases during use, therefore effective fire and explosion prevention measures must be taken. For example, setting up explosion-proof doors, installing combustible gas alarms, etc.
Electrical safety: Ensure correct wiring and good insulation of the electrical system to prevent fire or electric shock accidents caused by electrical faults. At the same time, pay attention to using power sources and cables that meet the requirements to avoid overloading operation.
5. Operating standards
Professional training: Operators should receive professional training to understand the performance, operating methods, and safety requirements of the equipment. Untrained or unauthorized personnel are not allowed to operate the equipment without authorization.
Compliance with regulations: Strictly follow the equipment operating procedures and safety guidelines, and do not arbitrarily change equipment settings or engage in illegal operations. During the operation, if any abnormal situation is found, the machine should be stopped immediately for inspection and reported to relevant personnel.
6. Maintenance and upkeep
Regular maintenance: Regularly maintain the atmosphere tube furnace, including cleaning the furnace tubes, inspecting heating elements, replacing seals, etc., to ensure the normal operation of the equipment and extend its service life.
Record management: Establish a comprehensive equipment usage record and management system, record the operation status, maintenance, and troubleshooting of equipment, and provide a basis for equipment maintenance and management.
In summary, it is necessary to pay attention to atmosphere control, temperature control, sample processing, safety protection, operating standards, and maintenance during the use of atmosphere tube furnaces. By strictly adhering to relevant regulations and requirements, the safe operation and efficient use of atmosphere tube furnaces can be ensured.
