●products information

1. Vanadium nitrogen is a addictive agent for iron and steel
2.VN can replace ferro-vanadium for steel-making.
3.Vanadium nitride could improve the strength, tenacity, ductility, thermal fatigue resistance and weldability.
4.For reaching the same steel strength, adding vanadium nitride could save vanadium up to 30-40% and reduce costs.


●comparison with Ferro- Vanadium

1.Vanadium is import ingredient in high-strength steel, and always exists in stable nitrogen and carbon compounds.

2. Nitrogen could improve the seperation of vanadium and make best use of vanadium.

3. Vanadium nitride alloy becomes import way of strengthing the iron and steel

4. VN could reduce the volume of iron and steel in construction field and lighten the weight of cars.

5. vanadium nitride could help upgrade the Ⅱscrew steel to Ⅲ screw steel.

6. vanadium nitrogen alloy could save energy and reduce cost.

7. The strength of iron and steel could improve 6Mpa with every more 10ppm nitrogen added in the iron mixed with vanadium.

8. the traditional method of increasing nitrogen is expensive, complicated, low absorption and unstable.

9. The technology of vanadium nitrogen alloy could improve the absorption rate of vanadium, lower cost for steelmaking.

How to use vanadium nitrogen

During steelmaking, the procedure of adding vanadium nitrogen is the same with the way of adding ferro-vanadium.
1. As for converter steelmaking, if without vacuum treatment, please add deoxidizer (e.g. Al Si Fe),Ferromanganese and vanadium nitrogen alloy to the molten steel in the steel ladle in turn during steel Tapping period.



2. In order to gain maximum return, vanadium nitrogen should be added in to the steel ladle directly during 1/3 steel Tapping period and should be finished before 3/4 steel tapping period.



3. After steel tapping period, blow argon to stir and to make sure that the vanadium nitrogen is fully melted.
