Vanadium nitrogen alloy is a new alloy additive which can replace ferrovanadium in the production of microalloyed steel.The addition of vanadium nitride to steel can improve the comprehensive mechanical properties of steel, such as strength, toughness, ductility and thermal fatigue resistance, and make the steel have good weldability.At the same strength, the addition of vanadium nitrogen alloy reduced the amount of vanadium addition by 30-40%, thus reducing the cost.
Vanadium nitrogen alloy is composed of vanadium pentoxide, carbon powder, surfactant made of raw materials, such as billet, under atmospheric pressure, nitrogen atmosphere protection, through 1500 ~ 1800 ℃ high temperature condition, reaction of vanadium nitride alloy.The key process equipment is the continuous atmosphere push plate high temperature furnace, which USES the silicon molybdenum rod and other electric heating elements to obtain the heat source
Vanadium – nitrogen alloys are used in structural steels, tool steels, pipe steels, rebar and cast iron.Vanadium-nitrogen alloy can be used in high-strength low-alloy steel to carry out effective vanadium and nitrogen micro-alloying at the same time, promote the precipitation of carbon, vanadium and nitrogen compounds in steel, and play a more effective role in sedimentation strengthening and grain refining
- It can strengthen and refine grain more effectively than ferrovanadium.
- Vanadium addition amount can be saved, vanadium nitrogen alloy can save 20-40% vanadium compared with ferrovanadium under the same strength condition.
- The yield of vanadium and nitrogen is stable, reducing the performance fluctuation of steel.
- Easy to use and low consumption.Adopt high strength moisture-proof packing, can directly into the furnace.
