Precautions for operating a continuous feeding and discharging rotary tube furnace

When operating a continuous feeding and discharging rotary tube furnace, attention should be paid to safety, efficiency, and equipment protection issues in the following aspects:
1. Equipment inspection and preparation
Comprehensive inspection of equipment:
Before use, a comprehensive inspection should be conducted on the rotary tube furnace, including whether the power supply, temperature control system, furnace, rotating mechanism, gas path system, and other parts are intact, whether there is any damage or abnormal situation.
Check if the circuit connections are correct, if the power supply is stable, and ensure that the equipment is in good condition.
Cleaning the furnace:
Clean the interior of the furnace to ensure there are no impurities or residues, so as not to affect the heating effect or cause safety accidents.
Check the airtightness:
Before introducing gas, the airtightness of the furnace and pipelines should be checked to ensure that gas does not leak.
2. Sample and material preparation
Sample preparation:
Prepare the required samples and ensure that they meet the processing requirements. Special attention should be paid to the safety of flammable, explosive, volatile, or corrosive materials.
Material selection:
Avoid using materials that may cause corrosion to the furnace or pipelines.
3. Precautions for operation process
Set appropriate parameters:
Set an appropriate heating rate and constant temperature to ensure that it does not exceed the maximum tolerance range of the equipment, avoiding equipment damage or safety accidents.
According to the process requirements, set the parameters such as gas flow rate and pressure.
Monitoring and adjustment:
During the heating and processing process, the changes in parameters such as temperature and gas flow rate should be closely monitored.
If any abnormalities are found, they should be adjusted or stopped in a timely manner, and professional personnel should be notified for inspection and handling.
Avoid over temperature use:
It is strictly prohibited to operate beyond the maximum operating temperature of the equipment to avoid damaging the equipment or causing safety accidents.
Do not open the furnace door:
During the work process, it is strictly prohibited to open the furnace door or perform other dangerous operations without authorization to avoid accidents.
Wear protective equipment:
Operators should wear heat-resistant gloves, protective goggles, masks and other protective equipment to avoid burns or splashes.
4. Equipment maintenance and upkeep
Regular cleaning:
Regularly clean and maintain the rotary tube furnace, including cleaning the furnace chamber, replacing thermocouples, and inspecting the rotating mechanism.
Inspection and maintenance:
Regularly calibrate and maintain equipment to ensure its accuracy and reliability. Especially the inspection of key components and equipment, such as reaction chambers, furnace doors, cooling systems, etc.
Professional maintenance:
The maintenance and upkeep of the equipment should be carried out by professional personnel to ensure its safety and stability.
5. Other precautions
Safe environment:
Ensure that there are no flammable materials or gases around the working environment of the rotary tube furnace to prevent safety accidents caused by ignition during high-temperature operation.
Prohibit corrosive experiments:
It is strictly prohibited to use a rotary tube furnace for experiments with corrosive substances to avoid damage to the equipment.
Record and Summary:
During the experimental process, detailed records of experimental conditions, operating procedures, data results, and other information should be kept for subsequent analysis and summary.
By strictly following the above operating precautions, the safe and efficient operation of the continuous feeding and discharging rotary tube furnace can be ensured, and the service life of the equipment can be extended.
