Product Description

LDMC-75A Vacuum High Pressure Gas Nitriding Furnace Used for  Tool Steel Die Steel with low temperature

Ion plasma nitriding furnace as a chemical heat treatment method to strengthen metal surface, is widely used in cast iron, carbon steel, alloy steel, stainless steel and titanium alloy. 
After the ion nitriding treatment, the hardness of the material surface can be significantly improved, so that it has high wear resistance, fatigue strength, corrosion resistance and burn protection.

Product Description

Nitriding furnace introduce:

Glow ionic nitriding furnace includes ionic triding and lon-carbonitriding .glow ionic nitriding furnace can significantly enhances the surface hardness of steel parts,resistance to damage,fatigue and corrosion;because it has the advantages for energy saving, save gas, high efficiency, good quality, no pollution, etc. It has been applied widely in power, machine tools, petrochemical machinery, textile machinery, mold and other industries.


Nitriding furnace features:
The main features of the pulse power glow ion nitriding furnace furnace system are as follows:
1. The vacuum furnace body adopts a "bell-type" design, which is flexible and convenient to operate and has good temperature uniformity.
2. The vacuum furnace body adopts a water-cooled double-wall structure, and the size of the bell jar is larger than that of the standard ion nitriding furnace of the same model, which is conducive to environmental protection and energy saving.
3. The furnace body is equipped with double-layer stainless steel heat shield, the furnace temperature is more uniform, and the performance of maintaining the nitriding layer (depth, hardness and structure shape) of the nitriding layer is better.
4. The cooling system of the furnace body adopts a multi-channel water cooling control system, which greatly improves the uniformity of the temperature in the furnace body.
5. With the integrated cathode and temperature measuring device, the real-time temperature in the furnace body is more real, the accuracy of temperature measurement is higher, and it also has better protection for the furnace body.
6. The use of high-quality fused cast mica has better anti-static strength for the supporting insulation of the cathode disc.
7. The stainless steel corrugated suction connection hose is not easy to age, and it is not easy to cause air leakage and other problems due to aging.
8. The furnace body is designed with an observation window, so that the working conditions of the furnace body can be observed at any time.

CHARACTERISTICS:
Increase of superficial hardness;
Improved resistance to wear and tear;
Improved resistance to stress;

FAQ

1. what is the different about Nitriding furnace and Vaccum furnace?
Ion nitriding, also known as glow nitriding, is carried out using the principle of glow discharge. Ion nitriding is to use the metal workpiece as the cathode furnace body as the anode in a low-vacuum furnace filled with nitrogen gas. After being energized, the nitrogen and hydrogen atoms in the medium are ionized under the high-voltage DC electric field, forming a plasma region between the cathodes. to adsorption and diffusion, nitrogen penetrates into the surface of the workpiece.
Under the action of a strong electric field in the plasma area, the positive ions of nitrogen and hydrogen bombard the surface of the workpiece at a high speed. The high kinetic energy of ions is converted into thermal energy, heating the surface of the workpiece to the required temperature. Due to the bombardment of ions, atomic sputtering is generated on the surface of the workpiece, which is purified. At the same time, due to adsorption and diffusion, nitrogen penetrates into the surface of the
workpiece.

The gas nitridingsystem workpiece is placed in the furnace, and the NH3 gas is directly injected into the nitride furnace at 500 to 550ºC, which is maintained for 20 to 100 hours, so that NH3 gas is decomposed into atomic (N) gas and (H) gas for nitriding. The main purpose is to produce a wear-resistant and corrosion-resistant compound layer on the surface of the steel.

2. Precautions for ion nitriding
The cleaning workpiece is nitridized with gas, but it is best to dry or cool and then put it into the furnace to save arcing time. The workpiece should be evenly loaded into the furnace. The interval between the workpiece and the cathode and anode must be more than 30mm, so as to avoid the excessive current density between the two poles and the local temperature of the workpiece being too high. Do a good job of anti-seepage. Any hole less than 2mm must be shielded, and the sample must be placed in a position that can be consistent with the temperature of the workpiece.

3.what kind of work piece can be use with Nitriding furnace ?
4Cr5MoSiV1(H13),3Cr3Mo3W2V,5Cr4W5Mo2V ,20 steel,40 steel,20Cr,20CrMnTi,40Cr/38CrMoAl,42CrMo, 50CrV,,1Cr18Ni9Ti,40 steel,alloy structural steel, bearing steel, spring steel, die steel, tool steel and other materials.

4. what's the max temperature nitriding furnace working for ?
Normal steel working temperature around 520-550 degree,if the Titanium alloy heating temperature must be around 750-800 degrees,this is customized type,you can inquire our sales technical manage.
