Precautions for using atmosphere tube furnace

As a precision experimental equipment, the atmosphere tube furnace requires strict adherence to a series of operating standards and safety guidelines during use. The following are precautions for using an atmosphere tube furnace:
1. Preparation before operation
Read the instruction manual: Please carefully read the product manual before use to understand the performance, operating methods, and safety requirements of the equipment.
Check the equipment: Ensure that there are no flammable or explosive materials around the equipment, check if the power and gas supply are normal, and make necessary adjustments.
Environmental requirements: For atmosphere tube furnaces using liquefied gases, it is required that the ambient temperature of the gas cylinder should not exceed 45 ℃ and ensure good indoor ventilation.
2. Operation process
Place the sample: Open the electric furnace door and place the object to be heated in the appropriate position, ensuring that the sample is in solid form and meets the requirements for the use of the furnace tube.
Set parameters: Set the required heating temperature and time, pay attention to following the usage restrictions in the product manual, reasonably control the heating and cooling rate, and avoid adverse consequences caused by too fast or too slow.
Start heating: Close the electric furnace door and start the heating program. During the heating process, pay close attention to changes in furnace temperature, adjust the heating power in a timely manner or take other measures to ensure that the furnace temperature does not exceed the rated value.
3. Safety precautions
Preventing burns: When the atmosphere tube furnace is heated, the temperature of the furnace tube is extremely high. It is strictly prohibited to touch the furnace tube directly with hands to avoid burns. If maintenance or inspection of the furnace tube is required, it should be ensured that the furnace tube has been sufficiently cooled and appropriate protective measures should be taken.
Gas safety: Atmosphere tube furnaces may involve the use of various gases during operation, such as nitrogen, hydrogen, oxygen, etc. These gases should be used in accordance with relevant safety operating procedures, such as regularly checking gas pipelines for leaks to ensure stable gas supply. At the same time, exhaust emissions should comply with environmental protection requirements to avoid polluting the environment.
Avoid corrosion and blockage: It is forbidden to pour liquid or metal substances into the atmosphere tube furnace to prevent corrosion or blockage of the furnace tubes.
Prevent accidents: It is strictly prohibited to open the electric furnace door without turning off the power or in a high temperature state to avoid burns or other accidental injuries. When running continuously for a long time, please regularly check the safety performance of the equipment and related pipelines.
4. Other precautions
Professional training: Personnel operating atmosphere tube furnaces should possess certain professional knowledge and operational skills, and have undergone relevant training. For beginners or untrained personnel, they should operate under the guidance of experienced operators.
Energy saving and consumption reduction: After the experimental work is completed, if no one continues to use it, please promptly turn off unnecessary power and gas sources to save energy and reduce safety hazards.
Equipment maintenance: Regularly maintain and upkeep the atmosphere tube furnace, such as cleaning the furnace tubes, inspecting heating elements, etc., to ensure the normal operation of the equipment and extend its service life.
In short, the use of atmosphere tube furnaces requires strict adherence to operating standards and safety guidelines. By proper operation and maintenance, the safe operation of the atmosphere tube furnace can be ensured, providing accurate and reliable experimental results for scientific research work.
