In terms of functions, sintering furnaces can be divided into two categories: ordinary sintering furnaces and protective sintering furnaces. The main function of ordinary sintering furnaces is to heat the workpieces to be sintered to the sintering temperature and then cool them down to sinter the workpieces. On the other hand, protective sintering furnaces can add some protective gases into the furnace to protect the sintered workpieces from oxidation and decarburization.
In terms of structures, the sintering furnace can be divided into box furnaces, tube furnaces, and mesh belt furnaces. Box furnaces are usually made of high-temperature resistant materials, and the heating elements are usually placed around the furnace. The sintering chamber is placed in the middle to sinter the workpieces. Tube furnaces have a small cylindrical cavity that can be heated, and the workpieces are usually placed in the cavity to be sintered.
Mesh belt sintering furnaces are usually used in the production of small parts, electronic components, and other products. The mesh belt moves forward in the furnace, and the parts are placed on the mesh belt to be sintered. Mesh belt sintering furnaces can also be divided into gas mesh belt sintering furnaces and electric mesh belt sintering furnaces. The former uses flammable gas as fuel for sintering, and the latter uses electricity as fuel for sintering.
According to the heating method, the sintering furnace can be divided into resistance sintering furnaces, radiation sintering furnaces, and microwave sintering furnaces. Resistance sintering furnaces use resistance as the heating element to convert electric energy into heat energy, which is then transferred to the workpieces. Radiation sintering furnaces use radiation as the heating source to sinter the workpieces. The radiation can be visible light, infrared, and so on. Microwave sintering furnaces use microwave as the heating source, and the materials with polar molecules produce heat under the action of microwave. Therefore, the parts to be sintered quickly reach the sintering temperature.
It can be seen that the metal powder sintering furnace has different types, and their functions, structures, and heating methods are different. With the development of technology, more new sintering furnaces will be produced to meet the needs of customers.
Specifications and Maintenance of Metal Powder Sintering Furnaces
Temperature Range: The working temperature range of a metal powder sintering furnace is typically between °C to °C. The specific temperature range required will depend on the material being sintered and the desired final properties.
Heating Rate: The heating rate indicates how quickly the furnace can increase its internal temperature. This is an essential specification for processes that require precise temperature control or rapid heating. Metal powder sintering furnaces typically have heating rates ranging from 10-50°C/min.
Temperature Uniformity: Temperature uniformity refers to the consistency of the temperature distribution within the furnace. It is crucial for ensuring the even sintering of metal powder parts and avoiding defects. Temperature uniformity is typically measured as a deviation from the setpoint temperature and expressed as a percentage or a specific value over the entire furnace or within specific zones.
Furnace Atmosphere: The atmosphere inside the furnace is another crucial parameter for the sintering process. Some metal powders require specific gas environments, such as inert gases, reducing gases, or vacuum, to prevent oxidation and achieve the desired sintering results.
Capacity: The capacity of a metal powder sintering furnace refers to the volume or weight of parts it can accommodate in a single batch. It is an essential specification for production efficiency and scalability. The capacity of a sintering furnace is usually measured in liters for volume and kilograms for weight.
Power: The power of a sintering furnace indicates the heating capacity and energy consumption of the equipment. It is an important specification for understanding the heating performance and operating costs of the furnace. The power of a sintering furnace is usually measured in kilowatts (kW).
Regular maintenance of a metal powder sintering furnace is essential to ensure its optimal performance and longevity. Here are some key maintenance practices:
Cleaning: Regularly clean the interior and exterior of the furnace to remove any residue or contaminants that could affect the sintering process or damage the furnace. Use appropriate cleaning solutions and tools to avoid damaging sensitive components.
Inspecting: Periodically inspect all components of the furnace, including the heating elements, thermocouples, insulation, seals, and control systems, for signs of wear, damage, or malfunction. Pay special attention to critical components like the heating elements and insulation.
Calibrating: Calibrate the temperature and pressure sensors of the furnace on a regular basis to ensure accurate and consistent measurement. This helps maintain the quality of sintered parts and process control.
Lubricating: If the furnace has moving parts or mechanical components, such as door mechanisms, fans, or pumps, lubricate them regularly to reduce friction and wear. Use appropriate lubricants for high-temperature applications to avoid contamination or damage.
Safety Precautions: When performing maintenance tasks on the furnace, always follow safety procedures and guidelines. This includes proper use of personal protective equipment, compliance with lockout/tagout procedures, and awareness of potential hazards.
