Description
Technical field
The invention belongs to field of metallurgy, prepares vanadium nitride with vanadic anhydride and iron oxide more particularly, to one kind and closes
The method of gold.
Background technology
Vanadium nitride, alias VN alloy, it is that only China and country of two, the U.S. can at present than the metallurgical technology of higher-end
With production, and the enterprise that can produce and few.
VN alloy is a kind of novel alloy additive, can substitute the production that vanadium iron is used for micro alloyed steel.Vanadium nitride
The comprehensive mechanical performances such as intensity, toughness, ductility and the thermal fatigue resistance of steel can be improved by making an addition in steel, and it is good to have steel
Solderability.In the case where reaching same intensity, addition vanadium nitride can save vanadium addition 30-40%, and then reduce cost.
By taking construction industry as an example, using the new three-level reinforcing bar of VN alloy technology production, because its intensity improves, not only strengthen
The security of building, shock resistance, but also can than saved using two level reinforcing bar 10%~15% steel.Only this one
, China can lack with about 7,500,000 tons of reinforcing bar every year, accordingly exploit about 12,400,000 tons of iron ore concentrate less, save 6,600,000 tons of coal,
Related 3,300,000 tons of auxiliary material is saved, while substantially reduce the number the discharge of the waste gas such as carbon dioxide and sulfur dioxide, receives resource
Save the double benefit with environmental protection.VN alloy can be used for structural steel, tool steel, pipe line steel, in reinforcing bar and cast iron.Vanadium nitrogen
Alloyapplication can carry out effective vanadium, nitrogen microalloying simultaneously in Aldecor, promote carbon, vanadium, nitrification in steel
The precipitation of thing, more effectively play sedimentation reinforcing and Grain refinement.VN alloy feature：VN alloy has more than vanadium iron
It is effective to strengthen and Grain refinement, can save vanadium addition using VN alloy, under the conditions of same intensity VN alloy with
Vanadium iron compares the vanadium that can save 20-40%.Vanadium, nitrogen recovery rate stabilization are more beneficial for using VN alloy, reduces the performance ripple of steel
It is dynamic.Particularly convenient using VN alloy, loss is few.Packed using high strength moistureproof, can directly enter stove.
