Adding a few percent of vanadium to the steel can increase the elasticity and strength of the steel, improve the wear and tear resistance, both high temperature and cold resistance, no wonder in the automotive, aviation, railway, electronic technology, defense industry and other sectors, the trace of vanadium can be seen everywhere. In addition, vanadium oxides have become one of the best catalysts in the chemical industry, known as "chemical bread". Mainly used in the manufacture of high speed cutting steel and other alloy steel and catalyst. Vanadium steel can be made by mixing it with steel. Vanadium steel is more compact than ordinary steel structures, and has higher toughness, elasticity and mechanical strength. Armor-piercing rounds made of vanadium steel, capable of penetrating steel plates 40 centimeters thick. However, in the steel industry, it is not the pure metal vanadium added to steel to make vanadium steel, but the direct use of vanadium-containing iron ore smelting into vanadium steel.
Vanadium has many excellent physical and chemical properties, so vanadium is very widely used, known as metal "vitamin". The initial vanadium is mostly used in steel, by refining the structure and grain of steel, improve the grain coarsening temperature, thereby increasing the strength, toughness and wear resistance of steel. Later, people gradually discovered the excellent improvement of vanadium in titanium alloys, and applied to the aerospace field, so that the aerospace industry has made breakthrough progress. With the rapid development of science and technology level, human requirements for new materials are increasing day by day. Vanadium is more and more widely used in non-steel fields, and its scope covers aerospace, chemistry, batteries, pigments, glass, optics, medicine and many other fields.
Vanadium is mainly used as an alloy additive in the steel industry, and the development of the steel industry is crucial to predicting the demand for vanadium. China's steel production is about 600 million tons, and the average consumption intensity of vanadium per ton is increased by 10g, which is equivalent to about 11,000 tons of vanadium pentoxide. In the United States, carbon steel and high-strength low-alloy steel are the steel with the largest amount of vanadium in the steel industry, accounting for more than 60% of the vanadium consumption in the steel industry, followed by high-alloy steel.
