Inside the factory, the molten iron containing vanadium must first be smelted into semi-steel with high carbon content that can meet the requirements of the next step of steelmaking, and then the substances in the molten iron must be selectively oxidized to a maximum extent and immersed in it. Among the vanadium slag, the obtained development will then be used as the basic raw material for extracting oxide-free vanadium in the next step. There are many methods to extract vanadium slag, but some methods have been eliminated by people, such as atomization to extract vanadium. Currently, there are four main methods to extract vanadium slag using molten iron: vanadium extraction with molten iron ladle and shaking ladle extraction. Vanadium extraction, air bottom blowing converter extraction and oxygen extraction.

In the conversion and extraction of vanadium, the conversion and extraction of vanadium is the process of oxidation reaction with various elements contained in the molten iron through the interaction between oxygen-colored sulfur and the metal surface. During the oxidation reaction, these elements Its speed often depends on some chemical components and kinetic conditions and thermodynamic conditions of the molten iron itself. The vanadium extraction in the converter borrows the principle of selective oxidation, which uses high-speed oxygen to stir the vanadium slag in the converter, thereby turning the material inside into a more stable counter-oxide, which can be used to make Taking vanadium slag is a physical and chemical reaction process. During the reaction process, operators can control the temperature of the overall reaction by adding coolant to the mesh, thereby achieving the purpose of removing impurities and purifying vanadium slag, and the reaction capacity often depends on the iron content. The affinity of each chemical substance in the water for the chemical substance oxygen. After the reaction is completed, the liquid iron element will stay inside the container, which is the semi-steel we want, and the solid vanadium slag will be placed inside the jar.
Vanadium Ferroalloys
Generally speaking, the lower the content of phosphorus, silicon oxide, and calcium oxide contained in vanadium slag, the higher the grade of vanadium slag will be.
