Vacuum rotary furnace

A vacuum rotary furnace is a device used for heating treatment in a vacuum or specific atmosphere, and is widely used in fields such as materials science, metallurgy, and chemical engineering. Its core feature is the ability to rotate and heat materials in a vacuum environment, ensuring uniform heating and efficient processing.

Working principle

Loading: Put the material into the furnace.
Vacuum pumping: Start the vacuum pump to achieve the desired vacuum level.
Heating: Start the heating system and raise the temperature according to the set program.
Rotation: Activate the rotation mechanism to evenly heat the material.
Cooling: After heating, cool down.
Material retrieval: Take out the processed material after cooling.

application area 

Materials Science: Used for powder metallurgy, ceramic sintering, crystal growth, etc.
Metallurgical industry: used for melting and heat treatment of metal alloys, rare earth materials, etc.
Chemical industry: used for catalyst preparation, polymer material processing, etc.
Electronics industry: used for heat treatment of semiconductor materials and electronic components.

advantage

Uniform heating: The rotary design ensures uniform heating of the material.
Efficient processing: Vacuum environment reduces oxidation and improves processing efficiency.
Precise control: Automated systems achieve precise parameter control.
Widely applicable: Suitable for various materials and processes.

The main structural components of a vacuum rotary furnace are as follows:

furnace body
Shell: usually made of stainless steel or carbon steel, with good sealing and high temperature resistance.
Inner liner: Made of high-temperature resistant materials such as ceramic fibers or stainless steel, used to carry materials.
vacuum system
Vacuum pump: used to extract gas from the furnace to achieve the required vacuum degree.
Vacuum gauge: monitors the vacuum level inside the furnace.
Valves and pipelines: Control gas flow and maintain a vacuum environment.
Heating system
Heating element: commonly used resistance wire, silicon carbide rod or molybdenum wire, providing uniform heating.
Insulation layer: reduces heat loss, usually using ceramic fibers or graphite.
slewing
Drive motor: Provides rotational power.
Rotary drum: carries materials and rotates with the motor to ensure uniform heating.
Bearings and seals: support the rotary drum and maintain sealing.
Cooling system
Water cooling jacket: used for cooling the furnace body and rotary drum.
Cooling fan: accelerates the cooling process.
control system
Temperature controller: Accurately control the temperature inside the furnace.
Speed controller: Adjust the speed of the rotary drum.
Vacuum controller: monitors and adjusts the vacuum level.
Data recording and monitoring system: Record and monitor operating parameters.
Feeding and discharging system
Feed inlet: used for material loading.
Discharge port: used for material extraction.
Sealing device: Ensure sealing during feeding and discharging.
security system
Pressure sensor: monitors the pressure inside the furnace.
Temperature sensor: monitors temperature to prevent overheating.
Alarm device: emits an alarm in abnormal situations.

These components together ensure the stable operation of vacuum rotary furnaces in high temperature and vacuum environments, and are widely used in fields such as material processing, metallurgy, and chemical engineering.
