Abstract

The invention discloses a by-product high-purity vanadium-nitrogen alloy production process and relates to the technical field of alloy production. In the present invention, ammonium metavanadate and carbon black are firstly mixed and pre-reduced into a base material by microwave calcination, then calcium silicate whiskers are added, combined with an ultrasonic step, the nitrogen fixation ability of the base material is improved, and the nitrogen content of the vanadium-nitrogen alloy is increased, and then Calcination under the coupling of electric field, pressure and microwave multi-fields makes the vanadium nitrogen alloy grow orderly, inhibits the formation of grains, and improves the compactness of the vanadium nitrogen alloy; in addition, the waste gas generated during the production process is sprayed and absorbed by ammonium sulfate to meet the emission standard , and the ammonium sulfate spray solution is enriched by resin adsorption, and then evaporated and crystallized to effectively improve the purity of ammonium sulfate. The vanadium-nitrogen alloy prepared by the invention has higher nitrogen content, and the produced by-products have higher purity.

Description

technical field

[0001] The invention relates to the technical field of alloy production, in particular to a production process of high-purity vanadium-nitrogen alloy by-product. Background technique

[0002] Vanadium-nitrogen alloy is a new alloying additive that can replace ferrovanadium in the production of microalloyed steel. The new grade 3 and above vanadium-containing steel bars produced by using vanadium-nitrogen alloy (vanadium nitride) technology, because of their increased strength, not only enhances the safety and earthquake resistance of buildings, but also saves 10 ~15% steel. At the same time, vanadium-nitrogen alloy has more effective strengthening and grain-refining effect than steel, and saves the amount of vanadium added. Under the same strength condition, vanadium-nitrogen alloy can save 20-40% of steel compared with ferrovanadium.

[0003] At present, vanadium pentoxide and vanadium trioxide are used as raw materials at home and abroad, and the heat uti...
