Vanadium nitrogen alloy is a kind of vanadium alloy products, composed of vanadium and nitrogen two elements, with high temperature strength, corrosion resistance and good processing properties, in iron and steel metallurgy and alloy materials and other fields have been widely used. The production process of vanadium nitrogen alloy generally includes raw material feeding, melting, tempering, centrifugation, pouring and other links
Vanadium nitrogen alloy has an important application in the field of steel, its main role is to improve the hardness of steel. The addition of vanadium nitrogen alloy to steel can reduce the grain size on the surface of steel, thereby increasing its hardness and strength. The alloy can also improve the electrical conductivity of steel, which is used in fields such as manufacturing electrical equipment and cables.
Vanadium nitrogen alloy is also widely used in electronic manufacturing, such as electronic components, semiconductor devices and so on. For example, it can be used to make capacitors to improve their electrical conductivity and stability. In the semiconductor industry, vanadium-nitrogen alloys are also commonly used to make conductor materials to improve their electrical conductivity.
Vanadium-nitrogen alloys are also widely used in aerospace. Due to its high strength and high corrosion resistance, it is extremely important in the manufacture of aerospace devices. For example, vanadium-nitrogen alloys can be used to manufacture aircraft engine impellers and superalloy materials.
Vanadium-nitrogen alloy has more effective grain strengthening and refining than iron vanadium. Moreover, the amount of vanadium added can be saved, and the vanadium nitrogen alloy can save 20-40% vanadium compared with iron vanadium under the same strength condition. Stable vanadium and nitrogen yield can reduce the performance fluctuation of steel. Easy to use, less loss. High strength moisture-proof packaging, can be directly into the furnace.
The main raw materials for the production of vanadium nitrogen alloy include iron, vanadium and nitrogen. The content of vanadium in ores is very small, so it needs to be extracted from ferrovanadite or vanadilmenite. In general, vanadium-containing oxides in ores need to be reduced to obtain metal vanadium. Nitrogen is generally extracted from the air.
In the production of vanadium nitrogen alloy, the purpose of mixing the charge is to make the composition of the final alloy meet the requirements and achieve the best effect. In the charge mixing, it is necessary to carry out accurate metering and mixing, especially the mixing ratio of iron vanadium and vanadium compound needs to be accurate.
In the production of vanadium nitrogen alloy, the main furnace types used are electric furnace, converter furnace, intermediate frequency furnace and so on. The electric furnace and intermediate frequency furnace are suitable for small batch and high quality production, while the converter is suitable for large batch production.
The smelting process is the core of the production of vanadium nitrogen alloy, including preheating, charge addition, furnace temperature control, smelting and pouring. In the smelting process, it is necessary to control the furnace temperature, operation mode and charge ratio and other parameters to ensure that the composition and quality of the final alloy meet the expected requirements.
After the smelting of vanadium nitrogen alloy, it is necessary to carry out follow-up treatment such as pouring and quenching. The casting process requires strict control of parameters such as temperature and speed to avoid loss or deformation of alloy quality. The quenching process can improve the hardness and strength of the alloy, but it is also easy to cause the brittleness of the alloy to increase, so it is necessary to choose the appropriate quenching method according to the specific situation.
