The electric heating high-temperature vacuum heat treatment furnace has the following characteristics:

1. Double layer furnace shell structure and rapid temperature rise and fall: The furnace body adopts a double layer furnace shell design, with a fan installed in the middle, which can achieve rapid temperature rise and fall while maintaining a low external temperature of the furnace shell, improving operational safety.

2. High precision temperature control: Adopting multi zone temperature control and PID adjustment method, the temperature display accuracy is 1 ℃, the temperature field stability is ± 5 ℃, and the heating rate can be set arbitrarily within the range of 1-20 ℃ to meet the heat treatment needs of different materials.

3. Excellent insulation performance: The furnace is made of high-temperature refractory bricks and alumina polycrystalline fiber vacuum adsorption, which has good insulation effect, strong thermal shock resistance, and resistance to high temperature and rapid cooling and heating.

4. Atmosphere control: Inert gases such as argon and nitrogen can be introduced and pre evacuated to provide an oxygen free or specific atmosphere for material heat treatment.

5. Intelligent control system: Equipped with an artificial intelligence control system, it has PID regulation, fuzzy control, and self-tuning functions. It can program various heating programs, be easy to operate, programmable, PID self-tuning, automatic heating, insulation, and cooling without the need for duty.

6. Multiple safety protections: The furnace door and roof are sealed with high-temperature silicone rubber, and the furnace door is equipped with a water cooling system. The furnace body is equipped with an air inlet, an air outlet, and a vacuum extraction port, which have multiple protection functions such as overheating, overcurrent, disconnection, and power-off, ensuring the safe and reliable operation of the equipment.

Customized service: Customization can be made according to user needs, such as furnace size, heating power, temperature control accuracy, etc., to meet the personalized needs of different users.

7. Energy saving and efficient: Using energy-saving materials and design, the energy consumption is only one-third of that of traditional electric furnaces, which is environmentally friendly and energy-saving.

High degree of automation: Heating, cooling, and other operations of metal workpieces require multiple actions to be completed, and the automation control system can accurately and timely coordinate the actions according to the program to avoid misoperation.

8. High quality heating and insulation materials: using materials such as tantalum, tungsten, molybdenum, and graphite that are resistant to high temperatures, have low vapor pressure, good radiation effects, and low thermal conductivity, suitable for working in vacuum and high temperatures.

9. Water cooling device: The furnace shell, furnace cover, water-cooled electrode, intermediate vacuum insulation door and other components are all equipped with water cooling devices to ensure normal operation under vacuum and heating conditions, preventing component deformation or damage.
