High temperature graphite vacuum furnace

High temperature graphite vacuum furnace is an excellent equipment in the field of material processing. Its core advantages are reflected in high temperature performance, vacuum environment, thermal conductivity, chemical stability, and intelligent control. The specific analysis is as follows:

1.Core advantages
Superior high-temperature performance
High temperature accessibility: The maximum temperature of the furnace can reach over 2000 ℃, and some equipment can even operate stably up to 2200 ℃. It is suitable for high-performance ceramics, refractory metals, carbon materials and other materials that require extremely high temperature treatment.
Good temperature uniformity: By reasonably arranging graphite heating elements and precision insulation structures, the temperature difference inside the furnace can be controlled within ± 5 ℃, ensuring uniform heating of materials and improving product quality consistency.
Vacuum environment ensures the purity of materials
Preventing oxidation: The oxygen content is extremely low in a vacuum environment, effectively avoiding the oxidation of metal materials (such as titanium alloys, nickel based alloys) and semiconductor materials at high temperatures, ensuring material purity and performance.
Removing impurities: Gas impurities and volatile substances (such as residual solvents) in materials at high temperatures will be extracted by a vacuum pump to improve material purity. For example, in carbon fiber production, a high-temperature graphite vacuum furnace can remove impurities from the fibers, improve fiber strength and modulus.
High thermal conductivity and fast response
Efficient heat transfer: Graphite is a good conductor of heat, with better thermal conductivity than most metals. It can quickly transfer heat to the material, shorten heating time, and improve production efficiency.
Uniform cooling: During the cooling process, graphite can also rapidly and uniformly cool the material, which is beneficial for controlling the material’s microstructure and properties.
Strong chemical stability
Corrosion resistance: Graphite has high resistance to corrosive media such as acids, alkalis, and salts, making it suitable for processing high-purity materials (such as semiconductors and magnetic materials) without introducing pollution or altering material composition.
Intelligence and automation control
Precise temperature control: Equipped with advanced sensors and control systems (such as PLC+touch screen), it can accurately control parameters such as temperature, vacuum degree, heating time, etc. It supports pre stored multiple process curves for easy access.
Data recording and analysis: Real time recording of temperature, vacuum degree and other data during the sintering process, supporting export and query, facilitating process optimization and quality control.

2. Technical features
Multi zone temperature control and uniform heating
The high-end model is equipped with a multi zone temperature control system, which ensures uniform temperature distribution inside the furnace by arranging graphite heating elements reasonably, making it suitable for complex heat treatment processes such as gradient material sintering.
Flexible atmosphere control
In addition to vacuum environment, protective gases such as argon and nitrogen can also be filled to create different atmosphere conditions and meet specific process requirements (such as anti oxidation treatment of metal materials).
Security protection mechanism
Equipped with safety devices such as overheating protection, thermocouple fracture protection, and water cooling system to prevent equipment from overheating damage or operational accidents, ensuring long-term stable operation.
Compact design and ease of operation
The equipment has a compact structure and beautiful appearance. Some models adopt a top electric door opening design, which is convenient for loading and unloading materials and improves operational efficiency.
