Characteristics of Ferro vanadium Nitride

1. Basic characteristics of ferro vanadium nitride: the main components of ferro vanadium nitride are vanadium, nitrogen and iron, containing two kinds of metals, and it is a true vanadium-nitrogen alloy. The ferro vanadium nitride produced by our company has high density, high absorption rate, stable product performance, and remarkable economic benefits. The product composition is stable between V66-72%N12-17%, and the product density can reach more than 5.2G/CM3. The ratio of nitrogen can reach 4.13, which is closer to the ideal ratio of vanadium and nitrogen of 3.64 compared with 5.5 of vanadium nitride. It has been proved by the application of many large domestic iron and steel enterprises that the addition of 0.5-0.7KG per ton of steel can save 12.5% of vanadium Resources, compared with adding ferro vanadium, the amount of vanadium added can be reduced by 50%.

2. The main application of ferro vanadium nitride: ferro vanadium nitride can greatly increase the strength of steel and improve the toughness of steel through grain refinement and precipitation strengthening; steel bars added with ferro vanadium nitride have low cost, Stable performance, small strength fluctuation, cold bending, excellent welding performance, basically no aging and other characteristics; adding ferro vanadium nitride does not need to change the current production process of Class II rebar in domestic iron and steel enterprises, and has no special requirements for temperature control and controlled rolling, especially It is suitable for my country's iron and steel enterprises to quickly realize the upgrading of rebar products from grade II to grade III, grade IV and even grade V rebar under the existing production equipment and process conditions.

 

Ferro vanadium nitride is also widely used in thin slab continuous casting and rolling high-strength strip steel, non-quenched and tempered steel, high-strength H-beam, high-speed tool steel, high-strength pipeline steel and other products, and the strength of steel is improved through microalloying , an economical and effective way to improve and enhance the toughness and other comprehensive properties of steel.
