What are the uses of fervanadium?
FeV is a rare metal with a wide range of applications. It is understood that vanadium is mainly used in alloys to change the properties of steel. At the same time, ferrovanadium has been commercially used in the United States, Canada, Europe, Japan, Australia and other countries. Its commercial uses are mainly used for wind power energy storage, photovoltaic energy storage and grid peak regulation. FeV80 is widely used in traditional fields such as bleaching, painting, and papermaking, and processed titanium is used in aerospace, military and other fields. Experts predict that with the rapid development of new energy and the improvement of performance requirements for steel, the future application prospects of these two materials will be very broad.
Iron Vanadium is known as "modern industrial monosodium glutamate" and is widely used in steel, chemical industry, aerospace and other fields. 85% of it is used in the steel industry. Adding Vanadium Iron to steel can improve the steel's wear resistance, strength, hardness, ductility and other properties. Adding 0.1% Industrial Ferrovanadium can increase the strength of steel by 10%-20%, reduce the structural weight by 15%-25%, and reduce the cost by 8%-10%.
Although ferrovanadium has many advantages, it easily causes environmental pollution during the production process. A large amount of toxic and harmful waste gas and waste water are emitted during the FeV alloy refining process. The exhaust gas contains hydrogen chloride, sulfur dioxide and sulfuric acid, which have devastating effects on vegetation and crops; the wastewater contains hexavalent chromium, cadmium, arsenic and other pollutants, which are very harmful to humans and animals and can easily form acid rain. Currently, production is shifting to underdeveloped countries and regions.
In addition, Vanadium Iron Alloy is also known as a "strategic metal". Ferrovanadium and its alloys have excellent properties such as corrosion resistance, high strength, high and low temperature strength, non-magnetic properties, good human adaptability, shape memory and superconductivity. Due to its light weight and high strength, it has been widely used in aerospace and other fields. In recent years, its application has gradually expanded to civilian industrial fields such as shipbuilding, petrochemical equipment, offshore platforms, power equipment, medical care, and consumer goods.
There are two methods for extracting iron vanadium from magnetite: the fire method is to extract iron vanadium indirectly from concentrate or vanadium slag, and the wet method is to extract iron vanadium directly from concentrate. At present, my country mainly adopts the method of indirect extraction of fervanadium. Pyrogenic vanadium extraction process: The ore dressing product vanadium concentrate is smelted directly in a blast furnace or electric furnace, so that most of the vanadium in the ore enters the molten iron, and then the water containing vanadium is sent to the converter for oxygen blowing to enrich the vanadium in the slag. Become vanadium slag. Vanadium peroxide is obtained from vanadium slag through roasting, leaching and filtration. A great advantage of this method is the high recovery rate of vanadium.
I hope that the above detailed introduction can give everyone a better understanding of Iron Vanadium Alloy. Generally speaking, this industrial raw material not only has a wide range of uses, but also has a relatively high commercial value. However, due to the complexity of the refining process, its price in the market is relatively high.
