Laboratory Graphitization Furnace

Laboratory Graphitization Furnace Description:

The laboratory graphitization furnace adopts a compact integrated furnace design. The furnace body, power supply, vacuum system, control system, etc. are integrated into a compact frame, which is small in size and requires only a minimum operating space. Install the casters under the frame, allowing the entire system to move easily. It is specially designed and produced for universities, scientific research institutes, and industrial research laboratories.

The

High Temperature Furnace for Carbon Materials Application:

Graphitization treatment of new carbon materials, including lithium battery negative electrode artificial graphite, carbon fiber, graphene, high thermal conductivity graphite, carbon fiber composite materials (C/C composite materials, C/ceramic composite materials), and other materials.
Natural graphite purification
Advanced ceramic sintering

Why can we achieve an ultra-high temperature of 3200 ℃ for graphitization to the optimum grade for your application?

The laboratory graphitization furnace adopts a medium-frequency induction heating method. A graphite susceptor is heated by induction. The energy is then transmitted to the treated parts by radiation.

Use a graphite hot chamber that can withstand extremely high temperatures. The graphite insulation surrounds a high-purity and high-quality graphite susceptor.

The pyrometer measures and controls temperature as under Argon environment, the maximum temperature is 3200 ℃. Optionally add a sliding thermocouple to measure temperatures at the beginning of the process as the initial temperatures are not high enough to be detected by the pyrometer.

Special-designed induction coils for rapid and efficient heating and excellent thermal uniformity.

Flexible and highly efficient IGBT power supply

Laboratory Graphitization Furnace features:

• Compact integrated design, small footprint, equipped with casters for easy movement and positioning
• The furnace shell adopts double-layer stainless steel and electropolish the inner surface for a clean, shiny, and durable surface.
• The insulation layer is hard and soft composite graphite felt, which has a good insulation effect, small heat loss, and long service life.
• The induction coil uses high-purity oxygen-free copper and adopts an integral casting insulation process with high safety performance.
• The vacuum system mainly speeds up the replacement of inert gases, and high vacuum is optional
• Using the induction heating method, the maximum temperature can reach 3000°C under an inert atmosphere, with a high heating rate and energy saving.
• Using high-purity graphite as the crucible and graphite felt as the insulation material, the thermal field environment is pure and pollution-free. The temperature uniformity is high and the thermal field material is easy to replace.
• Use an optical pyrometer to measure and control temperature (1000℃-3200℃). Equip with a thermocouple (0-1600°C) for low-temperature, which can automatically switch between high and low temperatures to achieve full temperature control.
• The main components are well-known international brands, with high measurement and control accuracy.
• Fully automatic control (retaining manual control), human-machine interface operation, full data monitoring and storage, safety interlocking, automatic alarm
