Operation and maintenance of nitriding furnaces

The main uses and principles of nitriding furnaces

A nitriding furnace is a device that uses nitrogen sources such as nitrogen or ammonia to nitride metal surfaces at high temperatures.
The principle of the nitriding furnace is to heat the nitrogen source to decompose it into active nitrogen atoms.
And then chemically react with the atoms on the metal surface to form a nitriding layer.
The main purpose of the nitriding furnace is to improve the hardness, wear resistance, corrosion resistance, and fatigue resistance of metal.

Explain the advantages and disadvantages of nitriding furnaces

The advantage of the nitriding furnace is that it can perform nitriding treatment at low temperatures without affecting the internal structure and performance of the metal.
The disadvantage of the nitriding furnace is that the thickness and uniformity of the nitriding layer are affected by factors such as nitriding temperature, time, atmosphere, and metal materials, and require precise control and adjustment.

It is also necessary to extend the nitriding furnace’s life and reduce operating costs.
The importance of operation and maintenance of the nitriding furnace is to avoid failure.
And damage to the nitriding furnace and ensure the safe and stable operation of the nitriding furnace.
The purpose of the operation and maintenance of the nitriding furnace is to optimize its performance.
Parameters of the nitriding furnace and improve its working efficiency and energy-saving effect of the nitriding furnace.

Nitriding furnace operation

Inspection items and preparations before operation of nitriding furnace

Check whether the power supply, gas source, water source, temperature controller, pressure gauge, flow meter, valve, furnace, furnace cover, furnace frame, and other components of the nitriding furnace are intact and working properly.
Clean the furnace and furnace cover of the nitriding furnace to remove dust and impurities to prevent affecting the nitriding effect.
Adjust the temperature, atmosphere, pressure, flow, and other parameters of the nitriding furnace.
Select the appropriate nitriding process according to different metal materials and nitriding requirements.
Place the metal parts to be nitrided into the furnace rack, maintaining a certain spacing and arrangement to avoid contact and influence between the metal parts.

Nitriding furnace operating procedures and precautions

Start the nitriding furnace, close the furnace lid, turn on the nitrogen source, and heat the furnace to reach the preset nitriding temperature.
Observe the temperature, pressure, flow, and other parameters of the nitriding furnace, and adjust and control them in time.
And maintain the stable operation of the nitriding furnace.
According to the requirements of the nitriding process, the nitriding time is generally controlled from a few minutes to a few hours.
After nitriding is completed, turn off the nitrogen source and lower the temperature of the furnace.
After it cools to room temperature, open the furnace cover and take out the nitrided metal parts.

Precautions:

The operation of the nitriding furnace should be carried out by professionals and abide by the operating procedures and safety regulations.
During the operation of the nitriding furnace, attention should be paid to observing the working status of the nitriding furnace.
Abnormal situations should be discovered and handled promptly.
After the operation of the nitriding furnace, the operating data of the nitriding furnace should be recorded.
The working effect of the nitriding furnace should be checked, and the performance and quality of the nitriding furnace should be evaluated.

Nitriding furnace maintenance

Routine maintenance and upkeep of nitriding furnace

Regularly clean the furnace and furnace cover of the nitriding furnace to remove the residue of the nitriding layer and the dust and impurities in the nitriding furnace.
Regularly check the power supply, gas source, water source, temperature controller, pressure gauge, flow meter, valve, furnace, furnace cover, furnace frame, and other components of the nitriding furnace, and promptly replace or repair any damage or failure.
Lubricate the moving parts of the nitriding furnace, such as the hinges of the furnace cover, the bearings of the furnace frame, etc., to reduce friction and wear.

Regular inspection and cleaning of nitriding furnace

At regular intervals, conduct a comprehensive inspection and cleaning of the nitriding furnace.
Detect the performance and parameters of the nitriding furnace, and evaluate the working status and effect of the nitriding furnace.
Use special cleaning agents and tools to thoroughly clean the furnace, and furnace cover.
Furnace frame, and other parts of the nitriding furnace to remove the residue of the nitriding layer and the dirt and oil stains on the nitriding furnace.
Use special testing instruments and methods to accurately measure and calibrate the temperature, pressure, and flow.
and other parameters of the nitriding furnace to ensure the accuracy and reliability of the nitriding furnace.

Nitrogen removal treatment and update of nitriding furnace

After the nitriding furnace has been used for a certain period, the nitriding furnace needs to be denitrified, that is.
The nitrogen in the nitriding furnace is discharged to prevent the accumulation and leakage of nitrogen.
The method of nitrogen removal treatment is to use inert gas (such as argon, helium, etc.) or air.
Which is injected from the entrance of the nitriding furnace and discharged from the exit.
Of the nitriding furnace until the nitrogen concentration in the nitriding furnace is reduced to a safe level, within the range.
After the nitrogen removal treatment, the nitriding furnace needs to be updated, that is.
The fresh nitrogen source is re-injected to restore the nitriding capability and effect of the nitriding furnace.
