Main furnace system features
1. The vacuum furnace body can be designed into a "bell" or "integrated" according to the needs of users, flexible and convenient operation.
2. Vacuum furnace with water-cooled double wall structure, furnace body size is the same type of standard ion nitriding furnace, is conducive to energy saving.
3. The furnace body configuration double heat shield (inner is made of stainless steel, the outer material is Aluminum Alloy), the temperature is more uniform, more significant energy saving.
4. The furnace cooling water cooling system using multiple advanced and practical to ensure more uniform temperature.
5. The cathode and the temperature measuring device adopts integrated design, temperature measurement is more real, more reliable and longer life.
6. The cathode plate insulating material supporting by casting mica excellent performance, high compressive strength, no worries breakdown.
7. Inflatable device with automatic control, reduce the labor intensity of operators.
8. Ion nitriding equipment by the general electric control system, vacuum furnace, carburizing gas distributing system, vacuum and maintaining system, composed of several vacuum measurement and control system .
9. Ion nitriding equipment according to the control system power types can be divided into DC power supply (LD) and pulse power supply (ldmc series. According to the different process control system of automation degree and function can be divided into basic type, double loop control, touch screen computer double closed loop control and touch screen computer process control model.

Q: What is the working principle of ion nitriding furnace?
A: Ion nitriding furnace is a device that uses glow discharge principle for nitriding treatment. In a vacuum furnace, an appropriate amount of nitrogen and other gases are introduced, and a high-voltage electric field is applied between the anode and cathode to ionize the gas and form plasma. The nitrogen ions in the plasma accelerate and bombard the surface of the workpiece under the action of an electric field, injecting nitrogen atoms into the surface of the workpiece, thereby achieving nitriding treatment and improving the hardness, wear resistance, corrosion resistance and other properties of the workpiece.
Q: What are the main components of an ion nitriding furnace?
A: It usually consists of furnace body, vacuum system, gas supply system, power supply system, temperature measurement and control system, and other parts.
Q: What are the main process parameters for ion nitriding?
A: The main process parameters include nitriding temperature, nitriding time, gas flow rate, gas pressure, power supply voltage, and current.
Q: How to choose appropriate process parameters based on the material and performance requirements of the workpiece?
A: For different workpiece materials, such as carbon steel, alloy steel, stainless steel, etc., their chemical composition and microstructure are different, and their response to nitriding process is also different.
