Introduction ：
Vacuum sintering furnace is a specialized heat treatment equipment designed for high-temperature sintering of powder metallurgy products, ceramics, composite materials, etc., in a vacuum or inert gas protective environment. Its core function is to induce physical and chemical changes such as diffusion, fusion, and densification between material particles through high-temperature heating, forming an integral workpiece with specific structure and performance. Meanwhile, it prevents materials from being oxidized, contaminated, or reacting with other substances at high temperatures.
Main Advantage
1.It can provide a vacuum environment, effectively preventing materials from oxidation at high temperatures and ensuring product purity and performance.
2.It allows precise control of process parameters such as heating rate, holding time, and cooling rate, ensuring a stable sintering process and improving the consistency of product quality.
3.It is suitable for sintering various high-melting-point and oxidation-prone materials, expanding the range of material processing.
4.It can reduce impurity contamination, lower the gas content in materials, and enhance product performance.
5.It enables near-net-shape sintering of complex-shaped components, reducing subsequent processing procedures and lowering production costs.
Related Configuration
1.Heating Chamber
Heating Chamber : Circular/Square
Heating Element : Graphite / Tungsten
The heating chamber consists of a stainless steel frame, heat insulation layer, heating elements, insulation parts, and a furnace bed. According to customer requirements, heating elements are made of different materials for various scenarios, with a maximum operating temperature of up to 1800℃ and excellent furnace temperature uniformity.
2.Vacuum system
Well-known domestic and foreign vacuum pump brands, such as EVP, Leybold, etc., are matched according to customer needs.
3.Control system
The operation control of this equipment is performed by the Siemens S7-1200 programmable logic controller. Interlock protection control is adopted for the equipment’s vacuum pump, valves, heating power supply, cooling fan, and other components. The system can judge and alarm abnormalities occurring during equipment operation, enabling fully automatic control. The network system supports remote network control and data transmission functions. All low-voltage components use international brands such as Siemens, Schneider, and Phoenix, which are highly reliable in terms of quality, performance, and craftsmanship, reducing the failure rate of the control system.
lThe network system supports remote network control and data transmission functions.
lRemote fault diagnosis, remote process debugging, etc.
lSupports software upgrade and update.
4.Other System
Our temperature measurement system adopts a 9-point temperature monitoring method to accurately monitor the product temperature in real-time, ensuring that the furnace temperature uniformity is maintained within the range of ±3℃ to ±5℃.The pneumatic system can be automatically controlled via a touch screen, enabling pneumatic control of the entire gas circuit.The gas charging system can be set up once without the need for re-adjustment; its on-off operation is realized through solenoid valves, making it simple, convenient, and easy to regulate.A water cooling system is also equipped, mainly used to control the temperature of the furnace body, vacuum pump, and heating electrodes, ensuring the normal operation of the vacuum furnace.
