Precautions for operating an intelligent box type atmosphere furnace

When operating an intelligent box type atmosphere furnace, it is necessary to pay attention to the following aspects to ensure the smooth progress of experiments or production processes and the safe use of equipment:
1. Equipment inspection and preparation
Equipment inspection: Before use, carefully inspect the furnace body, heating elements, thermocouples, atmosphere pipelines, and other components for integrity, damage, looseness, or leakage. At the same time, ensure that the power connection is normal, the grounding is reliable, and avoid circuit open circuits or leakage.
Complete accessories: Check if the box and accessories are complete, such as crucibles, furnace doors, seals, etc., to ensure that all components are in good condition.
2. Security protection
Personal protection: Operators should wear appropriate protective equipment, such as heat-resistant gloves, goggles, etc., to prevent harm to the body from high temperatures or corrosive gases.
Emergency measures: Understand and familiarize yourself with the location and operation of the emergency stop button in order to quickly cut off the power in case of an emergency and prevent the situation from escalating.
3. Sample placement and atmosphere control
Sample placement: When placing the sample, be careful not to touch the heating element and thermocouple to ensure that the sample is placed smoothly and evenly, without affecting the circulation of atmosphere and temperature uniformity in the furnace.
Atmosphere control: Confirm that the type, purity, and pressure of the atmosphere gas used meet the process requirements. Strictly follow the operating procedures for gas inlet, outlet, and flow regulation to prevent gas leakage. At the same time, pay attention to the uniformity and stability of the atmosphere to ensure the smooth progress of the experiment or production process.
4. Program settings and operation monitoring
Program settings: Carefully set the program parameters for heating, insulation, and cooling, including temperature, time, and rate, to ensure the accuracy of the program. For complex processes, multiple tests and optimization procedures may be required.
Operation monitoring: During the operation of the equipment, closely monitor the changes in parameters such as temperature, atmosphere pressure, flow rate, as well as the operating status of the equipment. If there are any abnormalities, they should be dealt with in a timely manner to prevent equipment damage or experimental failure. At the same time, regularly check the sealing condition of the equipment to prevent atmosphere leakage.
5. Cooling and cleaning maintenance
Cooling process: Follow the prescribed cooling method and rate for cooling, and do not forcefully cool quickly to avoid damaging equipment and affecting sample quality. After the temperature drops to a safe range, the furnace door can be opened to take out the sample.
Equipment cleaning: After each use, after the furnace body cools to a safe temperature, the impurities and residual substances in the furnace should be cleaned up in a timely manner to keep the furnace clean.
Regular maintenance: According to the requirements of the equipment maintenance manual, regularly maintain and upkeep the equipment. Including checking the performance of heating elements and thermocouples, replacing aging seals, etc. At the same time, pay attention to the anti-corrosion and rust prevention treatment of the equipment to extend its service life.
6. Other precautions
Electric furnace use: The electric furnace and controller must be used under conditions without conductive dust or explosive gases. Pay attention to the rated power and furnace temperature limits during use to avoid overloading operation.
Corrosive environment: Atmosphere furnaces should not be used in corrosive or volatile atmospheres such as acid, alkali, salt, etc., to avoid damage to equipment.
Personnel safety: Except for those conducting experiments, do not stay in the high-temperature furnace tube area to avoid burns or other safety accidents.
In summary, when operating an intelligent box type atmosphere furnace, attention should be paid to equipment inspection and preparation, safety protection, sample placement and atmosphere control, program setting and operation monitoring, cooling and cleaning maintenance, and other related matters. Only by fully understanding and adhering to these precautions can we ensure the smooth progress of experiments or production processes and the safe use of equipment.
