1. Definition
High temperature vacuum furnaces are mainly used to simulate high-temperature environments and perform various heat treatment operations by precisely controlling the surface temperature of the sample. It is widely used in various fields such as aerospace, semiconductor manufacturing, medical devices, etc., providing precise heat treatment solutions for these fields.

2. Characteristics
Double layer furnace shell structure: The furnace body of the high-temperature vacuum furnace adopts a double-layer furnace shell structure, and a fan is installed between the double-layer furnace shells to quickly raise and lower the temperature while maintaining a low external temperature of the furnace shell, improving operational safety.
High precision temperature control: The high-temperature vacuum furnace adopts multi zone temperature control and PID regulation, which can achieve high-precision temperature control. The temperature display accuracy is 1 ℃, the temperature field stability is ± 5 ℃, and the heating rate can be set arbitrarily between 1-20 ℃, which can meet the heat treatment needs of different materials.
Excellent insulation performance: The furnace is made of high-quality high-temperature refractory bricks and alumina polycrystalline fiber vacuum adsorption, which has good insulation effect, thermal shock resistance, high temperature resistance, and resistance to rapid cooling and heating. At the same time, the use of stainless steel furnace material ensures that the surface of the furnace is not hot to the touch at high temperatures, further improving the safety of the equipment.
Atmosphere control: The high-temperature vacuum furnace can be filled with inert gases such as argon and nitrogen, and can be pre evacuated to provide an oxygen free or specific atmosphere for material heat treatment.
Intelligent control system: The temperature control system of the high-temperature vacuum furnace adopts artificial intelligence regulation technology, which has PID regulation, fuzzy control, self-tuning functions, and can be programmed with various heating programs. Easy to operate, programmable, PID self-tuning, automatic heating, automatic insulation, automatic cooling, no need for duty.
Safe and reliable: The door and top of the high-temperature vacuum furnace are sealed with high-temperature silicone rubber, and the door is equipped with a water cooling system. There are air inlets, air outlets, and vacuum extraction ports on the furnace body. In addition, the equipment also has multiple protection functions such as overheating, overcurrent, disconnection, and power-off, ensuring the safe and reliable operation of the equipment.
Customized service: High temperature vacuum furnaces can be customized according to user needs, such as furnace size, heating power, temperature control accuracy, etc., to meet the personalized needs of different users.
