Ferrovanadium nitride is a new type of vanadium-nitrogen alloy additive. From a performance point of view, ferrovanadium nitride is far superior to ferrovanadium and vanadium nitride. It is mainly used in high-strength spiral steel bars and high-strength pipeline steel. , high-strength steel (H-beam, I-beam, channel steel, angle steel), thin slab continuous casting and rolling high-strength steel strip, non-quenched and tempered steel, high-speed tool steel and other products.
The main components of ferrovanadium nitride are vanadium, nitrogen, and iron. It contains two metals and is a true vanadium-nitrogen alloy. Ferrovanadium nitride has high density, high absorption rate, stable performance, and significant economic benefits. The vanadium-to-nitrogen ratio can reach 4.13, which is closer to the ideal vanadium-to-nitrogen ratio of 3.64 than the 5.5 of vanadium nitride. It has been proven by application that adding a ton of steel The amount is 0.5-0.7KG, which can save 12.5% of vanadium resources. Compared with adding ferrovanadium, the amount of vanadium added can be reduced by 50%.
Ferrovanadium nitride can greatly increase the strength of steel and improve the toughness of steel through grain refinement and precipitation strengthening. Steel bars added with ferrovanadium nitride have the characteristics of low cost, stable performance, small strength fluctuation, cold bending, It has the characteristics of excellent welding performance and basically no aging. Ferrovanadium 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 steel, high-speed tool steel, high-strength pipeline steel and other products.
