Details Of Powdered Ferrovanadium

Powder ferrovanadium is a kind of ferrovanadium alloy, which is widely used in iron and steel metallurgy industry because of its low cost, convenient processing and obvious effect. The vanadium contained in it has a strong deoxidation and reduction effect, which can significantly improve the tensile strength, hardness and toughness of steel, and also enhance the wear resistance, corrosion resistance and mechanical properties of steel.

The dissolution of powdered ferrovanadium is generally carried out by metallurgical method. Commonly used oxidants are sodium hydroxide, basic sodium carbonate and ammonium chloride. In the process of dissolution, the following points should be noted:
1. Selection of suitable dissolving agent: generally, a dissolving agent with good uniformity, strong dissolving ability for ferrovanadium and low volatility is selected for dissolution.
2. Control the dissolution temperature: the dissolution temperature is generally between 70℃ and 100℃, and too high temperature will lead to the failure of the ferrovanadium catalyst.
3. Control the dosage and adding time of oxidant: The control of oxidant quantity directly affects the reaction balance. Excessive oxidant will lead to the oxidation of metal elements such as iron and vanadium, and finally affect the quality of products.
4. Pay attention to safety: during the dissolution process, pay attention to keep the operating environment well ventilated to avoid the explosion danger caused by exothermic reaction.
