The composite vanadium nitrogen can be used in structural steel, tool steel, pipe steel, reinforcement and cast iron. Vanadium nitrogen alloy can be used in high-strength low alloy steel for effective vanadium and nitrogen microalloying at the same time, to promote the precipitation of carbon, vanadium and nitrogen compounds in steel, and play the role of settling strengthening and grain crystallization more effectively.

Characteristics: it is more effective than ferrovanadium in strengthening and refining grai

In the same strength condition, vanadium nitrogen alloy can save 20-40% vanadium compared with iron vanadium.

The yield of vanadium and nitrogen is stable, reducing the fluctuation of steel performance.

Easy to use and less wastage. High - strength moisture - proof packaging, can be directly into the furnace.

Composite vanadium nitrogen is made of vanadium pentoxide, toner, active agent and other raw materials, under the protection of atmospheric pressure, nitrogen atmosphere, after 1500 ~ 1800℃ high temperature state, reaction to form vanadium nitrogen alloy. Its key process equipment is the continuous atmosphere push plate high temperature furnace, using silicon molybdenum bar and other heating elements to obtain the heat source.

There are two kinds of crystal structure of vanadium nitrite: one is V3N, hexagonal crystal structure, extremely hard, microhardness is about 1900HV, melting point can not be measured; VN, density 6.13. Relative molecular weight 64.95. Planar center-cubic crystal structure, microhardness about 1520HV, melting point 2360 degrees. They all have high wear resistance.
