Precautions for using rotary tube sintering furnace

Rotary tube sintering furnace is a professional equipment used for sintering and calcining granular powders in industries such as powder metallurgy, ceramics, refractory materials, lithium positive and negative electrode materials, and new energy. When using a rotary tube sintering furnace, the following precautions should be taken to ensure the safe operation of the equipment and sintering effect:
1.Preparation before operation
Check equipment:
Check if the circuit of the rotary tube sintering furnace is connected correctly to avoid short circuits or poor contacts.
Check whether the furnace and furnace tubes are clean, free of impurities or residues.
Check the sealing to ensure good sealing at connections such as furnace doors and flanges to prevent gas leakage.
preheat:
Before formal sintering, the equipment should be preheated to gradually increase the temperature and voltage, avoiding damage to the equipment caused by rapid heating.
Sample preparation:
Place the sample to be sintered in a suitable container and ensure its position is centered for uniform heating.
2.Operation process
Atmosphere control:
According to the sintering process requirements, introduce appropriate gases (such as nitrogen, argon, etc.) and adjust the flow rate and pressure.
It is strictly prohibited to close the exhaust valve when ventilating into the furnace tube to prevent danger caused by the increase in pressure inside the furnace tube.
Temperature control:
Set the appropriate sintering temperature and monitor temperature changes to ensure that the temperature remains stable within the set range.
Be careful not to use at excessive temperatures to avoid damage to the equipment or affecting the sintering effect.
Furnace tube rotation:
Activate the furnace tube rotation function to evenly heat the material inside the furnace.
Adjust the rotation speed according to the material characteristics and process requirements.
3.Safety precautions
Fire and explosion prevention:
Flammable and explosive materials or gases are strictly prohibited from being placed around the rotary tube sintering furnace to prevent fires or explosions during high-temperature operation.
It is strictly prohibited to use a rotary tube sintering furnace for experiments with corrosive substances to prevent equipment corrosion or the production of toxic gases.
Electrical safety:
Ensure the safety and reliability of the power supply circuit to avoid electric leakage or shock accidents.
Install a leakage protection switch to ensure that the power supply can be cut off in a timely manner in case of leakage.
Operating standards:
Operators should wear protective equipment (such as gloves, eye masks, masks, etc.) to prevent high temperatures or harmful gases from causing harm to the human body.
It is strictly prohibited to open the furnace door during the operation of the rotary tube sintering furnace to prevent injury from high-temperature gas or flame spraying.
Maintenance and upkeep:
Regularly clean the furnace and furnace tubes to keep the equipment clean and tidy.
Regularly inspect the sealing, electrical circuits, and critical components of the equipment to ensure that it is in good condition.
If any abnormal situation or malfunction is found in the equipment, it should be stopped immediately and professional technicians should be contacted for inspection and maintenance.
In short, when using a rotary tube sintering furnace, it is necessary to strictly follow the operating procedures and safety precautions to ensure the safe operation of the equipment and sintering effect.
